A total of 993 individual trees having ≥5 cm dbh (671 trees ha -1 ) of 99 species belonging to 73 genera and 36 families were recorded from the forests of Chunati. The forest has diverse floristic resources that seemed from the Shannon Wiener's diversity index (3.353), Margalef's richness index (14.201) and Simpson's dominance index (0.090). Total basal area of tree species was 12.47 m 2 ha -1 , where Dipterocarpus turbinatus showed highest basal area (2.62 m 2 ha -1 ) followed by Acacia auriculiformis (1.39 m 2 ha -1 ). Importance Value Index (IVI) was found maximum (40.11) for Acacia auriculiformis followed by Tectona grandis (16.46) plantation species. On the other hand, importance value Index was highest for Dipterocarpus t...

For this organic fractions namelyethanol, chloroform and n-hexane have been investigated for antimicrobial, anti-diarrheal, anti-inflammatory and membrane stabilization, α-glycosidase inhibitory and antipyretic activities. Results suggest that in the antimicrobial sensitivity study, ethanol and chloroform fractions produced inhibition zones with the ranges of 12 to 20 mm and 7 to 21 mm, respectively; where they strongly inhibited the growth of Shigella sonnei, Escherichia coli, Shigella dysenteriae and Microsporum sp. Crude fractions also revealed the presence of antidiarrheal, antiinflammatory and membrane stabilization, anti-amylase as well as antipyretic activities. In conclusion, it should be mentioned that D. auricularia may have one of the good sources for phytotherapy.
