  • Quality control methods for fruit extracts of Kigelia africana using high performance thin layer chromatography
    Kunjan B. Bodiwala, Nancy Banker, Rahul Lalwani, Mamta B. Shah, and Anuradha K. Gajjar

    Informa UK Limited
    Kigelia africana is a tree native to Africa but also found in eastern and southern parts of India with reported anti-bacterial, anti-inflammatory, and immunomodulatory activities. Verbascoside, caffeic acid and ferulic acid are important markers for the quality control of the plant. Two different HPTLC methods were developed and validated; method - 1 for estimation of verbascoside and caffeic acid while method - 2 for estimation of caffeic acid and ferulic acid. Developed methods were applied to the methanolic fruit extract to determine the quantities of markers. Both methods were found to be linear, specific, precise, accurate, sensitive and robust. Results indicated that both methods can be used for quantitative determination of verbascoside, caffeic acid and ferulic acid in fruit extract. The developed methods may be utilised as a part of the quality control and standardisation for the raw material and extracts of Kigelia africana and can also aid to chromatographic fingerprinting of the plant.

    Bentham Science Publishers Ltd.
    Abstract: Aesculus L. is a genus of 12 to 19 woody species, representing one of the most acclaimed examples of inter-continental incoherence of the plants native to temperate regions of the Northern Hemisphere. It is traditionally valued in Ayurveda and the Chinese system of medicine for its various species that possess antitumor, cardioprotective, anti-inflammatory and neuroprotective activities. Current studies on this genus have revealed the presence of specific saponins with a multispectrum of pharmacological actions and therapeutic applications. A repertoire of literature related to the biological, taxonomical, phytochemical and ethnopharmacological aspects of Aesculus genus and its uses in different indigenous populations was explored. An inventory of all the species of this genus that were found to be useful as per ethnopharmacological literature was prepared. The ethnobotany, phytochemistry and pharmacology of the individual species are outlined in this review. The extensive information cited here has adduced the likely areas where the important species of this genus can illustrate significant therapeutic intervention in the management of chronic disorders including diabetes, hypercholesterolemia and cancer. The wide range of its pharmacological actions is attributed to the distinct phytochemicals occurring in the species, especially the triterpenoidal saponins like aescin. This review amplifies the recent studies on phytochemical and pharmacological aspects, which alludes that these species have noteworthy therapeutic potential.

    Abstract A validated UHPLC-PDA with an ESI-MS/MS method has been developed for simultaneous estimation of six bioactive alkaloids (magnoflorine, berbamine, columbamine, jatrorrhizine, palmatine and berberine) in the different extracts of the roots of Berberis aristata DC (Family:Berberdiaceae). It is an important medicinal herb native to Northern Himalaya and commonly known as ‘daruharidra’, ‘daruhaldi’, ‘Indian barberry’ or ‘tree turmeric’. An insight into the research literature uncovered reports on isoquinoline alkaloids like magnoflorine, berbamine, columbamine, jatrorrhizine, palmatine, and berberine as major bioactives in B. aristata roots, possessing different pharmacological and therapeutic effects. In the present study, these aforementioned alkaloids were separated on Phenomenex Luna®, 5 µm-C8 analytical column. The HPLC-MS analysis was performed at a flow rate of 0.90 mL min−1. Each alkaloid that is resolved was characterized by precursor ions and fragment ions with electrospray ionization (ESI) source in both positive and negative ionization using scan mode. The limit of detections (LODs) were 0.087, 0.727, 0.035, 0.124, 0.782 and 0.794 μg mL−1 for magnoflorine, berbamine, columbamine, jatrorrhizine, palmatine and berberine, respectively. The proposed UHPLC-PDA method was fully validated according to international (ICH) guidelines and was found to be selective, sensitive and highly accurate for the concomitant estimation of the aforementioned symbolic bio-markers of B. aristata roots.

    Basera Ishita A., Verma Preeti D., Bhatt Vijay P., and Shah Mamta B.

    Open Science Publishers LLP
    Hippophae salicifolia D. Don, belonging to Elaeagnaceae family, exhibits dioecy and is extensively used for multipurpose due to its medicinal and nutraceutical potential. Although several research works have been carried out on the plant, no information is available regarding the impact of its dioecious nature on its phytochemicals and subsequent pharmacological properties. The present study is aimed at development of a high performance thin layer chromatography (HPTLC) method that is specific and reliable for the estimation of a marker compound gallic acid in both female and male counterparts of this dioecious plant, thus evaluating gender impact on chemical profile of the plant. For each sample, an ethyl acetate fraction of the hydrolyzed hydroalcoholic extract of H. salicifolia was prepared and applied on pre-coated plates of silica gel G 60F254. After developing the plate in the solvent system, toluene:ethyl acetate:formic acid (5:4:1, v/v/v), the identification and estimation was carried out by densitometric scanning at 270 nm. The presence of gallic acid was confirmed by UV overlay of the spot resolving in test tracks with that of reference standard. The results suggested quantitative variation of the marker compound in female and male plants, indicating a clear gender bias. The proposed validated HPTLC method is simple, yet specific and accurate and would contribute to the quality assessment of H. salicifolia.

    Walter de Gruyter GmbH
    Abstract Objectives Based on the ethno-medicinal use of Bombax ceiba leaf, in the treatment of diabetes, the present study is aimed at evaluation of antidiabetic potential of leaf extract and its major constituent mangiferin. Methods Efficacy of hydroalcoholic extract of Bombax ceiba leaf (BCL, 200 and 400 mg/kg body wt.) and mangiferin (MF, 20 mg/kg body wt) was studied in streptozotocin (STZ)-induced diabetic rats and associated complications visually, retinopathy, cardiopathy and nephropathy. After 20 days, serum glucose, lipid profiles, glycol-hemoglobin % (HbA1c%), liver enzymes activity and glycogen content, and histopathology of the pancreas were corroborated. The study was coxswained for development of validated RP-HPLC method for the estimation of MF in BCL. Results The results demonstrated significant reductions in the levels of glucose (p<0.001), glycated hemoglobin (HbA1c%, p<0.001), cholesterol, triglycerides and low-density lipoproteins, and concurrent elevation of high density lipoproteins level in the groups administered BCL and MF relative to the controls. It significantly reversed most of the altered metabolic and oxidative stress parameters and histopathological changes. Mangiferin content in BCL was found to be 0.04%w/w. Conclusions The anti-diabetic effects of BCL may be attributed to its ability to enhance insulin release, antioxidant and hypolipidemic potential.

    Frontiers Media SA
    Historically, plants have been sought after as bio-factories for the production of diverse chemical compounds that offer a multitude of possibilities to cure diseases. To combat the current pandemic coronavirus disease 2019 (COVID-19), plant-based natural compounds are explored for their potential to inhibit the SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2), the cause of COVID-19. The present study is aimed at the investigation of antiviral action of several groups of phytoconstituents against SARS-CoV-2 using a molecular docking approach to inhibit Main Protease (Mpro) (PDB code: 6LU7) and spike (S) glycoprotein receptor binding domain (RBD) to ACE2 (PDB code: 6M0J) of SARS-CoV-2. For binding affinity evaluation, the docking scores were calculated using the Extra Precision (XP) protocol of the Glide docking module of Maestro. CovDock was also used to investigate covalent docking. The OPLS3e force field was used in simulations. The docking score was calculated by preferring the conformation of the ligand that has the lowest binding free energy (best pose). The results are indicative of better potential of solanine, acetoside, and rutin, as Mpro and spike glycoprotein RBD dual inhibitors. Acetoside and curcumin were found to inhibit Mpro covalently. Curcumin also possessed all the physicochemical and pharmacokinetic parameters in the range. Thus, phytochemicals like solanine, acetoside, rutin, and curcumin hold potential to be developed as treatment options against COVID-19.

    Oxford University Press (OUP)
    Abstract In this study, a simple and rapid LC with tandem MS method was developed and validated for the simultaneous determination of kaempferol and quercetin in Thespesia populnea extract. The compounds were eluted using a Gemini C18 column (50 × 2.0 mm, 3 μm), with the mobile phase consisting of acetonitrile–0.3% formic acid in water at the flow rate of 0.400 mL/min. The assay exhibited a linear dynamic range of 25–2500 ng/mL for both kaempferol and quercetin. The values for intra- and interday precision and accuracy were well within the generally accepted criteria for analytical methods (<15%). Selectivity, linearity, LOD, LOQ, accuracy, and precision were evaluated for both analytes. The proposed method is accurate and sensitive and can be used for the routine quantification of kaempferol and quercetin in the herbal extract and in polyherbal formulations.

    Akademiai Kiado Zrt.
    Oldenlandia corymbosa Linn. (Rubiaceae) is an important herb traditionally used as a febrifuge and liver tonic. In this study, a high-performance thin-layer chromatography (HPTLC) method has been established for the quantification of four bioactive markers, oleanolic acid (OA), ursolic acid (UA), lupeol (LU), and stigmasterol (ST), in the whole plant of O. corymbosa. Separation was achieved on silica gel 60 F254 HPTLC plates using hexane-ethyl acetate-methanol (8.2:1.8:0.5, v/v) for oleanolic acid and ursolic acid; and toluene-methanol (9.4:0.6, v/v) for lupeol and stigmasterol as the mobile phases. The quantitation of the four markers was carried out using the densitometric scanning at 540 nm after derivatization using sulfuric acid reagent. The linear regression analysis data for the calibration plots showed a good linear relationship (r2 = 0.9831–0.9979) in the concentration range of 1200–4200 ng for oleanolic acid, 400–1400 ng for ursolic acid, 100–500 ng for lupeol, and 500–2500 ng per spot for stigmasterol with respect to area. The method was validated for linearity, inter-day precision, intra-day precision, repeatability, accuracy, specificity, limit of detection, and limit of quantification. The average recoveries for oleanolic acid, ursolic acid, lupeol, and stigmasterol were 98.77 to 99.12%, indicating the good reproducibility. Stigmasterol 1.19 ± 0.04% w/w was present at high concentration, and oleanolic acid 0.012 ± 0.006% w/w was present at low concentration in the whole plant powder. The proposed HPTLC method was found to be simple, precise, sensitive, accurate, reproducible, and robust.

    EManuscript Technologies
    Context: Bryonia laciniosa Linn. (Cucurbitaceae) seed is used in traditional medicine for a number of ailments including metabolic disorders. Aim: This study evaluated the anti-diabetic action of the ethanol extract of B. laciniosa seeds and saponin fraction of it through its effect on hyperglycemia, dyslipidaemia and oxidative stress in neonatally streptozotocin (n-STZ)-induced diabetic rats (n-STZ diabetic rats). Materials and Methods: Ethanol extract (250 and 500 mg/kg; p.o.), saponin fraction (100 and 200 mg/kg; p.o.) and standard drug glibenclamide (3 mg/kg; p.o.) were administered to diabetic rats when the rats were 6 weeks old and continued for 10 consecutive weeks. Effects of ethanol extract and saponin fraction on various biochemical parameters were studied in diabetic rats. Results: The treatment with ethanol extract and saponin fraction for 10 weeks decrease in the levels of glucose, triglycerides, cholesterol, high-density lipoprotein, low-density lipoprotein, very low-density lipoprotein, serum urea, serum creatinine and diminished activities of aspartate transaminase, and alanine transaminase. The anti-hyperglycemic nature of B. laciniosa is probably brought about by the extra- the pancreatic mechanism as evidenced from unchanged levels of plasma insulin. B. laciniosa modulated effect of diabetes on the liver malondialdehyde, reduced glutathione (GSH), superoxide dismutase (SOD), and catalase (CAT) activity. Administration of ethanol extract and saponin fraction to diabetic rats showed a significant reversal of disturbed antioxidant status. Significant increase in SOD, CAT, and levels of GSH was observed in treated n-STZ diabetic rats. Conclusion: The present study reveals the efficacy of B. laciniosa seed extract and its saponin fraction in the amelioration of n-STZ diabetic rats.
