STUDY ON THE CHEMICAL COMPONENTS AND BIOACTIVITIES OF ELSHOLTZIA CILIATA IN VIETNAM

Abstract

   Thirty four compounds were identificated in both n-hexane (EH) and ethyl acetata(EE) extracts of Elsholtzia ciliata, including fatty acids (both saturated fatty acids andunsaturated fatty acid), terpenoids and steroids by GC-MS. The total phenolic andflavonoid contents in EH and EE extract were investigated, the results showed thattotal phenolic index were 79,20 and 48,98 mg galic acid /100g dry sample; totalflavonoid index were 23,15 mg và 10,42 mg catechin/100g dry sample. The halfmaximal inhibitory concentration (IC50) of both n-hexane (EH) and ethyl acetata (EE)extracts were over 256 ppm while Acarbose (reference) with IC50 of 176,86 ppm.
