Nowadays, traditional plant study has grown in importance as their use has been increased. Tectona grandis (teak) is one of several plants that have been studied for its phytochemical and pharmacological properties. This plant includes a number of secondary metabolites, which may explain its diverse pharmacological properties. Although teak leaf compounds have been examined in the past, there is still little information on the diversity of teak leaf compounds. As a result, we are employing several methodologies to determine the total flavonoids content, phenolic content, water extractable matter, ethanol extractable matter, total ash content, and other component analysis of teak leaves. We found that the average of total flavonoid content in the teak leaves is about 3.93 {\textpm} 0.008\%w/w, while the average total phenolic concentration in teak leaves is about 4.3{\textpm}0.15\%w/w. The Gas Chromatography- Mass Spectrometry GC-MS study of the methanol extract of T. grandis leaves also found twenty-three active chemical compounds (phytochemical components)

The antioxidant activity of Annona squamosa (A. squamosa) leaf was carried out using methanol extract and fractionated extract namely n-hexane, ethyl acetate and residue. The antioxidant activity of methanol extract and fractionated was performed using the 1-diphenyl-2-Pycrilhydrazil (DPPH) method. The antioxidant activity test of methanol extract and fractionated n-hexane, ethyl acetate and residue yielded IC50 of 6.87, 169.99, 31.55 and 44.75 ppm. The ethyl acetate fraction extract with IC50 31.55 ppm was performed by column chromatography using silica gel G60 as the stationary phase and n-hexane: ethyl acetate as the mobile phase. The results of column chromatography obtained 181 fractions and were combined based on the stain pattern into 4 subfractions. Antioxidant test of each subfraction showed that the ASE 3 subfraction had the strongest antioxidant activity. Furthermore, the subfraction was analyzed using Gas Chromatography Mass Spectrometry (GC-MS). According, GC-MS data analysis showed that the third subfraction contained 19 phytochemical compounds, where 3 compounds having the highest concentration, namely 4,4{\textquoteright}-((p-Phenylene)diisopropylidene) diphenol, dodecanoic acid, methyl ester and phthalic acid, isobutyl 2-methylpent-3-yl ester.

Background: Cichorium intybus commonly called as chicory or coffee weed was traditionally used for the treatment of various ailments associated with liver, kidney and heart. The aim of the present study was phytochemical screening, in-vitro evaluation of antioxidant potential, element analysis of wild and cultivated chicory and GC-MS analysis of methanolic leaf extract of wild chicory grown in Kashmir Himalaya. Method: To achieve this goal, the qualitative and quantitative analysis was done to determine the antioxidant potential. Element analysis was done using AAS and metabolite fingerprinting was done using GC-MS to ascertain the presence of active phytoconstituents in chicory leaves. Results: The qualitative screening of leaf extracts from wild and cultivated chicory indicates the presence of important bioactive constituents. The leaf extract of wild chicory constituted the higher amount of total phenol and flavonoid contents and also showed strong radical scavenging activities of DPPH, SOD and hydrogen peroxide radical as indicated by lower values of IC50 compared to cultivated chicory. Furthermore, both extracts of wild chicory showed the highest total antioxidant potential for the reduction of Fe3+ to Fe2+ when compared with cultivated chicory. The results from the elemental analysis shows that leaf extract of wild chicory exhibits higher concentration of elements as compared to cultivated one, thus can be used as a potential bio-fortified crop. The GC-MS analysis determines the presence of 78 different compounds in the methanolic leaf extract of wild chicory. The major phytochemical constituents were phytol (7.96\%) and stigmat-5-en-3-ol (6.45\%). Conclusion: The findings of the present study suggested the therapeutic potential of chicory leaves; particularly wild chicory proves to be a potent source of natural antioxidant against free radical associated damages. Metabolite profiling study revealed important metabolites having potent pharmacological actions.

Context and Aim: Exacum lawii (Gentianaceae) is bitter folk medicinal herb. The study deals with molecular investigation by DNA fingerprinting profile of Exacum lawii, quality control and phytochemical standardization of Exacum lawii. Methods: The DNA fingerprinting profile was performed by RAPD technique using 3 pairs of primers. The quality control standardization was done as per the WHO guidelines and official methods of AOAC. Phytochemical standardization employed quantitative estimations of phytoconstituents by spectrophotometric and identification using GCMS technique. The quantification of Swertiamerin and Ursolic acid in Exacum lawii was carried by HPLC. Results: Macroscopical and microscopical examination confirmed the diagnostic morphological and histological features. The content of vitamins, minerals and fatty acids were estimated. Physicochemical parameters obtained within the provided limits as per WHO. The phytochemical screening of ethanolic extract and its fraction revealed the presence of alkaloids, flavonoids, phenols, tannins, terpenoids, glycosides and steroids Total phenolics (57.4mg/g tannic acid equivalent), total tannins (15.3 mg/gm), total flavonoids (51.4 mg/gm rutin equivalent), total flavonols (5.4 mg/gm) and carbohydrates (12.6 mg/gm D-fructose equivalent) content were estimated using spectroscopic techniques. The GC-MS data revealed 20 compounds. Swertiamerin and Ursolic acid content was 119.59 mg/gm and 5.34 mg/gm respectively. Conclusion: Present study provides the referential information to develop a monograph for quality control standardization of Exacum lawii.
