    Results in Chemistry, 2026
    The present study aimed to compare three extraction methods for the quantity and identification of phytochemicals from Pogostemon benghalensis leaf extract using FTIR and GC–MS, and to evaluate their antibacterial and pancreatic lipase (PL) enzyme activity. Ultrasonication-assisted extraction (UAE) was found to be the most efficient method for extracting phenols (47.40 mg GAE/g) and flavonoids (31.78 mg RTE/g), suggesting further research on UAE techniques for phenol content. GC–MS analysis identified key bioactive compounds such as eugenol, hexadecenoic acid, and cis-vaccenic acid in all extraction methods. UAE yielded 50 compounds, microwave-assisted extraction (MAE) 39 compounds, and Soxhlet-assisted extraction (SAE) yielded 35 compounds. The UAE extract showed significant antibacterial activity and 57 % PL enzyme inhibition at 100 mg/ml, comparable to the standard drug orlistat. The extract also exhibited dose-dependent inhibition of alpha-amylase and alpha-glucosidase, indicating its potential as an alternative to synthetic drugs. This study provides a comparative analysis of extraction methods for P. benghalensis constituents and their anti-obesity effect in vitro . • Ultrasonication-, microwave- and solvent-extraction were adopted for P. benghalensis leaf. • UAE was the most effective method for high- yield of secondary metabolites. • FTIR and GC–MS revealed the functional groups and compounds in the leaf extract. • UAE-extract showed highest pancreatic lipase enzyme inhibition at 100 mg/mL. • UAE-extract revealed dose-dependent inhibition of α-amylase and α-glucosidase.

    Micropropagation of Medicinal Plants Volume 2, 2024
    The Oxalidaceae family is known for small herbs, shrubs and small trees with economic and medicinal properties in folklore medicines. The genus Oxalis is distributed worldwide and is famous for tuberous and ornamental cultivars. The present study established reproducible in vitro protocols for mass multiplication of Oxalis corniculata L. via. micropropagation and indirect organogenesis using different explants. Murashige and Skoog (MS) medium augmented with various cytokinins, auxins and gibberellic acid and combinations with respect to the different protocols. In micropropagation, shoot tip and node explants cultured on a medium with 6-benzyl adenine (BA) 3.0 mg/L, 6-furfuryladenine (Kn) 1.0 mg/L and naphthalene acetic acid (NAA) 0.5 mg/L produced the highest average of 35.1 and 28.5 shoots after 25 days of culture, respectively. Gibberellic acid (GA3 ) treatment was satisfactory in shoot elongation, and rooting of shoots was best on indole-3-butyric acid (IBA) 3.0 mg/L than indole-3-acetic acid (IAA) and NAA. In indirect organogenesis, internode, leaf and petiole explants produced green, compact nodular calli at varying frequencies on medium fortified with auxins. The maximum frequencies of shoot regeneration and shoot numbers were observed on a medium containing BA 1.0 mg/L and IBA 0.5 mg/L. Further, the shoot elongation was achieved with BA and GA3 , and rooting was best achieved on IBA 3.0 mg/L with Kn 0.5 mg/L. All the plantlets were successfully hardened and acclimatized under the greenhouse condition with maximum survival of 95%. The current protocols established via meristem and callus mediated cultures would help in bioprospecting of this less explored medicinal plant.

    Agriculture and Natural Resources, 2019
    An efficient in vitro micropropagation protocol from shoot tip explants was established for Tinospora cordifolia (Willd.) Miers. Young and mature shoot tip (YST and MST, respectively) explants from two different-aged plant sources (15 d and 3 yr) were treated simultaneously to develop and compare their efficacy in the micropropagation protocol. Among the cytokinins and synergetic treatments, 6-benzyladenine (BA; 2.0 mg/L) and kinetin (KN; 1.0 mg/L) responded better in bud break and shoot development, at both individual concentrations and in combination. Addition of the auxin indole-3-acetic acid (IAA; 0.5 mg/L) to the optimal cytokinin concentrations of BA (2.0 mg/L) with KN (1.0 mg/L), enhanced multiple shoot induction and shoot growth. Further supplementation of gibberellic acid (0.1 mg/L) and an antioxidant (ascorbic acid at 100 mg/L) significantly enhanced the shoot bud induction, shoot number and shoot length. Assessment of different basal media using the best plant growth hormone complex confirmed that the Murashige and Skoog (MS) medium best supported shoot bud break and shoot development in both the shoot tip explants. The best rooting response was from half-strength MS medium fortified with indole-3butyric acid (0.5 mg/L), resulting in approximately 80% of the plantlets successfully acclimatized both at in vitro and in vivo conditions. In conclusion, the YST explants responded better than the MST explants in all aspects of growth and development and proved that the age of explants was an important determinant for efficient micropropagation in T. cordifolia.
  • Somatic embryogenesis from stem thin cell layers of Dendrobium aqueum

    Biologia Plantarum, 2018
    An efficient in vitro regeneration protocol through somatic embryogenesis was established from stem transverse thin cell layers (tTCLs) of Dendrobium aqueum Lindley, an imperiled orchid. This study outlines the induction and successive maturation stages of D. aqueum somatic embryos (SEs). The tTCLs (~ 0.5 mm thick) cultured on halfstrength Murashige and Skoog (MS) medium containing cytokinins and auxins, either individually or in combination, produced embryogenic callus (EC). Treatment with 0.5 mg dm-3 zeatin induced EC in 41.42 % of tTCLs. As many as 42.66 globular SEs per tTCL were formed in the presence of 1.5 mg dm-3N6-(2-isopentyl) adenine (2iP) but only on 10.33 % of explants. The combined treatment of 2iP (1.5 mg dm-3) and 0.5 mg dm-3 6-benzyladenine resulted in 34 globular SEs on 14.7 % of tTCLs whereas the combination of 2iP and 1.0 mg dm-3 indole-3-butyric acid (IBA) induced 7.4 globular SEs on 52.33 % of tTCLs. Supplementation of activated charcoal, amino acids, and antioxidants alleviated browning at all the concentrations tested, but the EC response declined. The addition of 0.5 mg dm-3 polyvinylpyrrolidone to 1.5 mg dm-3 2iP and 1.0 mg dm-3 IBA produced 24 SEs on 19.89 % of tTCLs suggesting that the EC and SEs can be effectively induced by individual cytokinins whereas the synergistic treatments with other compounds can only enhance the induction of EC. Histological observations of EC showed the formation of globular SEs from sub-epidermal regions. Successive developmental stages of globular SEs and the intermediate stage of protocorm like bodies until the formation of plantlets were observed. The plantlets obtained through SEs showed no morphological variations, and inter simple sequence repeat profiles also confirmed the genetic fidelity of in vitro-derived progeny with high monomorphism (97.78 %). In conclusion, the use of stem tTCLs is an effective method to produce SEs through indirect somatic embryogenesis in D. aqueum.
