Objective: The increasing prevalence of drug-resistant pathogens has gained the attention of pharmaceutical and scientific communities toward potential antimicrobial agents from plant-derived sources. The present work deals with the extraction, screening, and characterization of antimicrobial compounds from Alstonia scholaris against various pathogenic micro-organisms. Methods:The components of crude extracts obtained after soxhlet extraction of plants were characterized through thin layer chromatography (TLC) and gas chromatography-mass spectrometry (GC-MS). The antimicrobial effect was checked at different concentration against Bacillus subtilis MTCC 121, Staphylococcus aureus MTCC 96, Escherichia coli MTCC 43, Klebsiella pneumonia MTCC 432, Pseudomonas aeruginosa MTCC 424, and Streptococcus pyogenes MTCC 497. Results and Conclusion:A. scholaris extract showed a significant antibacterial effect against selective pathogens. The bioactive compounds were separated and identified by TLC and GC-MS, respectively.

“…Khyade and Vaikos, 2009 reported the presence of alkaloids, flavonoids, reducing sugars, simple phenolics, steroids, saponins and tannins in the leaves of the same plant 13 . Standardization of herbal drugs is a topic of great concern because of the great variability derived from heterogeneous sources.…”

Alstonia scholaris (L.) R. Br. is a plant of family Apocynaceae and has a great medicinal importance. It is widely used by tribal people to treat various diseases and ailments. The present communication deals with the organoleptic and preliminary physico-phytochemical studies of the stem bark of the plant. The organoleptic study was done according to the W.H.O. guidelines for medicinal plants. The physicochemical parameters viz. loss on drying, ash values and extractive values were calculated. Soxhlet extraction of the powdered plant material was done with 80% ethanol and then partitioned with petroleum ether, ethyl acetate and n-butanol subsequently. The percentage yields of different solvent fractions were calculated and then they were subjected to preliminary phytochemical screening which indicated the presence of alkaloids, carbohydrates, tannins, terpenoids, saponins, flavonoids, steroids and fixed oils and fats.

Nature has gifted our planet with abundance of medicinal plants wealth that are cherished with several useful pharmacological properties. Each and every plant has some medicinal property in one or the other way, only we have to know and explore their uses in particular doses and conditions. There are lots of herbs, which are not much studied scientifically though they are used for some ornamental or other purposes like Alstonia scholaris or Saptaparna. The herb has plenty of medicinal values that boost up brain mechanism and can be used in brain disorders. They are anti inflammatory, anti oxidant and free radical scavenging, immune-stimulating and anti choline esterase. In the present review, the researches related with nootropic effect of Alstonia scholaris has been enlightened.
