The medicinal plant Gymnema sylvestre found in the Indian subcontinent and Srilanka is known for its anti-diabetic, diuretic, anti-obesity, anti-cancer, antimicrobial, anti-inflammatory properties. The current study is focused on the phyto compound extraction efficiency of different solvents like ethanol, methanol, ethyl acetate, hexane, benzene and chloroform by gas chromatography{\textendash}mass spectrometry analysis of Gymenma sylvestre. From the results, it is concluded that G. sylvestre leaves extracts contains more than 38 phyto compounds with natural antioxidants potential. Further analysis of the extract will help in identifying the effective compounds which can be of potent use in the pharmacological field.

Introduction: Madang gatal (Schima wallichii) Choisy is one of typical Indonesian plants that used traditionally as insomnia and hypertension drug. Background: The environment is highly polluted by free radicals which may contribute to the aging process of tissue and cause chronic diseases. The aims of the research were to study the phytochemical constituents and free radical scavenging activity of Schima wallichii stem bark. Materials and Methods: Extraction of S.wallichii stem bark was carried out by maceration method using methanol and then the methanol extract was partitioned using n-hexane, ethyl acetate and butanol successively. The methanol extract was then screened to determine the presence of different classes of secondary metabolites. The ethyl acetate fraction was subjected to silica column chromatography followed by exclusion chromatography on sephadex LH-20 to yield two partially purified isolates, SA and SE4. FTIR and GC-MS analyses indicated SA asa mixture of pentadecanoic acid, 14-methyl-, methyl esterand patchouli alcohol, while SE4 was made up predominantly of pentadecanoic acid, 14-methyl-, 13-hydroxy methyl ester. Free radical scavenging activity was performed by using2,2-diphenyl-1-picrylhydrazyl (DPPH) radical oxidation method. Results: The phytochemical screening indicated the presence of alkaloids, flavonoids, tannins, saponins, terpenes and quinones. All tested samples, methanol, n-hexane, ethyl acetate and butanol extracts showed strong antioxidant activity with IC50 values of 8.58, 17.36, 8.17 and 8.79 μg/mL, respectively. The isolates showed strong antioxidant activity with SE4 exhibiting an IC50 value of about 5.5 times stronger than quercetin used as a standard antioxidant.

Background: Asparagus racemosus is a climber shrub used in Indian medicine for centuries. It has been used as galactogogue and nerve tonic in folk medicine. The recent research on A. racemosus has revealed its disease fighting properties such as anti-bacterial, immunomodulatory, cardio protective, anti-stress, etc. Phytochemicals present in the plants are associated with their therapeutic capabilities. Hence, phytochemical screening of a therapeutic plant is essential. Materials and Methods: A preliminary qualitative screening of phytoconstituents present in the ethanol and aqueous extract of the plant was done. high-performance thin layer chromatography (HPTLC) was used to create a phytochemical fingerprint of the plant extract. Further, a series of antioxidant assays, i.e., 2,2-diphenyl-1- picrylhydrazyl (DDPH) radical, Nitric oxide (NO) radical, Superoxide (SO) radical and 2,2{\textquoteright}-azinobis( 3-ethylbenzothiazoline-6-sulphonic acid) (ABTS) radical scavenging assays were done. Results: The phytochemical screening and the HPTLC fingerprint showed the presence of phenolic compounds, flavonoids, glycosides, triterpenoids, saponins etc. They also showed free radical scavenging property and hence can be used as potential primary antioxidant. Conclusion: A preliminary screening created a phytochemical profile of A. racemosus extracts. These phytoconstituents may be linked to the various known therapeutic applications of the plant. This may aid in further extensive studies for identifying and isolating compounds with potential therapeutic value in A. racemosus.
