Pemisahan Dan Isolasi Terpenoid Dari Serbuk Gergaji Dan Kulit Shorea Leprosula Miq Sebagai Antirayap

Abstract

Terpenoids separation and isolation from the bark and saw dust of Shorea leprosula Miq have been carried out using hexane and dichloromethane as a solvent. The hexane crude extract of the bark showed most active in terms of antitermite activity. The mortality of the termte range from 72.0-91.3 for the concentration of extract range from 5.0-45.0%. The colomn fractination from hexane crude extract of the bark by hexane-dicloromethane gradient yield sevent fraction, and only two fraction showed the activity with 57.3% and 62.7% mortality resppectivelly. While from the % termite attact, A fraction showed better activity than B fraction. Qualitative analysis with specific reactions showed that the A fraction presumed to be a sesquiterpenoids lactone with the ketone functional group
