Background: Strobilanthes kunthianus T Anders (Neela kurinji) is well known for its medicinal properties and reported to possess many biological activities. However, so far there is no phytoconstituents are isolated and reported in S. kunthianus. Objective: The present study aimed to isolate and characterize the chemical constituents present in various parts of S. kunthianus. Methods: The successive petroleum ether root and stem extracts, chloroform stem extract, macerated and crude methanol flower extracts were subjected to column chromatography for the isolation of constituents. All the isolated compounds were characterized based on their physical and spectral data analysis. Results: Ten compounds were isolated and being reported for the first time from S. kunthianus. Except lupeol (1 and 2), betulin (3), α-amyrin (5) and β-sitosterol (7), other five compounds including of 3,5-bis-(dimethylcarbamoyl)methyl)-4-(11- cyclohexylundecyl)-4-heptyl-N1,N1,N7,N7 tetramethylheptanediamide (4), 4-amino-tetrahydro- 2H-pyran-3,5-diol (6), 2-(2-hydroxyethyl)-3-methyl-4-((E)-3,6-dimethylundec-4-enyl)cyclohexyl propionate (8), flavone glycoside (9) and decahydro-1,1,4a,8-tetramethylphenanthren- 2(1H,3H,4bH)-one (10), isolated from S. kunthianus were novel. Conclusion: The novel compounds need to be further investigated for ascertain pharmacological activities which will be useful for further drug development.

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.
