Phytochemical analysis of the methanolic extract from the mangrove species Avicennia marina plant species inhabited in coastal water Perumal Govindhan Natural Product Research, 2026 The mangrove, a vital ecosystem, faces significant threats from climate change, human actions, and pollution. This study aims to evaluate the presence and distribution of trace metals (Cu, Cd, Ni, Pb, and Zn) in Avicennia marina leaves and sediments, shedding light on A. marina's antioxidant capabilities amidst metal pollution. Samples were gathered from Pichavaram coastal areas. Various pollution indices such as contamination factor (CF), pollution load index (PLI), and bio concentration factor (BCF) were utilised to gauge pollution levels. Analysis via LC/MS,1H & 13C-NMR, and GC/MS revealed 52 compounds in the methanolic extract of A. marina notably; the extract contains pentanoic acid, decanoic acid, diethyl hydroxylamine, pyrrolidine, 4-chlorophenyl, octadecylisocyanate, thiazolidinones, and arabinopyranoside. These compounds exhibit diverse biological properties, such as antioxidative, anticancer, antimicrobial, anti-inflammatory, antiallergic, antiaging, and antiartherosclerotic effects, making them promising herbal medicines with minimal adverse effects and maximum efficacy, thereby improving the quality of life during treatment.
Phytochemical screening, elemental analysis and physicochemical properties of the oil from Bauhinia variegata seeds Perumal Govindhan Natural Product Research, 2026 Plants have served as the foundation of traditional medicine since the earliest civilisations. In light of this, it is crucial to study the phytochemical and physicochemical properties of Bauhinia variegata seed oil to discover novel secondary metabolites. Seed extracts were obtained through successive Soxhlet extraction using methanol and petroleum ether. The particle size of 0.25 mm achieved the highest bio-oil yield at 24.8%. The bio-oil was characterised using various techniques, including FTIR, GC-MS, and 1H & 13C NMR. Elemental analysis revealed the presence of Pd (0.03 ± 0.01 ppm), Cd (0.003 ± 0.007 ppm), Cr (0.02 ± 0.05 ppm), Zn (0.02 ± 0.008 ppm), Mg (0.04 ± 0.01 ppm) and Na (0.45 ± 0.05 ppm). The bio-oil was further analysed for basic properties, and phytochemical compounds, revealing the presence of alkaloids, glycosides, carbohydrates, phenolics, tannins, saponins, flavonoids and terpenoids. The study highlights the biomedical, biodiesel and industrial applications of bio-oil.
Characterisation analysis of bio oil generation using Hibiscus cannabinus seeds Govindhan P Natural Product Research, 2025 Bio-oil from Hibiscus cannabinus seeds was extracted with four solvents: acetone, benzene, isopropanol, and hexane. Solvent extraction techniques have less oil residue than other methods. The primary factors that influence the extraction processes such as extraction time, particle size, seed ageing, and solvent suitability were optimised to enhance the bio-oil yield. The extracted bio-oil was tested by GC-MS, FTIR, and 1H-NMR. Physicochemical properties (free fatty acid, specific gravity, acid value, calorific value, saponification number, iodine number, etc.) of hibiscus cannabinus oil were also analysed on a dry weight basis. The hexane solvent gave the highest yield (25.37%) followed by acetone (21.32%), Benzene (16.98%), and Isopropanol (14.20%) over 3.5 h. It is also predicted that the cost of Hibiscus cannabinus seed bio-oil per litre is Rs. 230 which is moderately economical Hibiscus cannabinus oil has a calorific value of 39,895 kJ/kg, making it a better fuel choice.
Environmentally friendly swift and perfect extraction procedures for analysing the phytochemistry and proximate nutritional biochemistry of biomaterial processed from Avicennia marina leaves Thamizharasan S, Govindhan P, Gurunathan K, Sathishkannan G, Edison Chandraseelan R Natural Product Research, 2025 Conventional extraction methods have mislaid their best possible performance because of the slow extraction process using demand in inexperienced and innovative technologies. Concerning this view, several eco-friendly novel techniques alienate to develop by us for the entire extraction of nutrients and phytocompounds from plant sources. The specific organic, inorganic chemical compounds have been explored using ultra sonication and GC-MS assisted techniques. The results are evident to facilitate the ultrasonic and GC-MS supported extraction descent that is less solvent consumed, green analytical methods suitable for complete speedy bioactive compounds drawing out. This study has revealed the occurrence of nutrients, phytochemicals, with biological value, and also the GC-MS analysis exposed 20 peaks through 20 individual chemical compounds, and all the compounds are deliberated as energetic medicinal bioactive compounds. Likewise the FE-SEM is used to find out the topographical characteristics of biomaterial and the FTIR analysis.
