ABSTRACT
OBJECTIVE:
To study the chemical constituents from the stems of Piper betle.METHODS:
Various chromatographic techniques were used to isolate and purify the constituents. The structures of these compounds were elucidated on the basis of spectral analysis.RESULTS:
Nine compounds were isolated from the petroleum ester and ethyl acetate soluble fractions of the 70% acetone extract and their structures were identified as 6beta-hydroxystigmast-4-en-3-one (1), beta-sitosterol (2), stigmasterol (3), oleanolic acid (4), 23-hydroxyursan-12-en-28-oic acid (5), beta-sitosterol-3-O-beta-D-glucoside-6'-O-palmitate (6), beta-daucosterol (7), (2S) -4'-hydroxy- 2,3-dihydroflavonone-7-O-beta-D-glucoside (8) and alpha-ethyl glucoside (9).CONCLUSION:
Among these compounds, 1, 3 -9 are isolated from this plant for the first time.
