PHARMACOGNOSTICAL, PRELIMINARY PHYTOCHEMICAL SCREENING AND ANTIBACTERIAL ACTIVITY OF METHANOL EXTRACT OF MURRAYA KOENIGII

 

 

RESULT AND DISCUSSION -
The yield of extract in methanol was found to be 17.1% on dry weight .ash parameter, Extractive values were evaluated. The preliminary phytochemical screening of Extract showed the presence of Carbohydrate, Glycoside, Alkaloids and Proteins are detected.

Antibacterial screening data showed that methanol extract has exhibit antibacterial activity.

CONCLUSION
Methanol extract showed that presence of alkaloids, carbohydrate, Proteins, volatile oils and glycosides.

From antibacterial screening it was found that methanol extract showed  Best antibacterial activity in the concentration 100 µg/ml .the methanol extract showed the zone of inhibition 6.2 mm .this is an indicated the methanol extract of murrayakpenigii shows they inhibit growth of microorganism.
