(Euphor- biaceae) is a deciduous tree or shrub, which grows
wild in the forest of the piedmont through Taiwan. The plant
is used in Tai- wan-folk medicine for the treatment of
inscecticide and antifla- mmatory. From the methanolic extracts
of the roots of this plant, friede- lin, oleanolic acid,
olean-12-en-3β,28-diol, β-amyrin acetate, 6β-
hydroxystigmast-4-en-3-one, stigmast-4-en-3-one ＆ stigmast-
4,22-dien-3-one, 5α-stigmast-3,6-dione, phytosterols (campes-
terol, 11.44%; stigmasterol, 52.00﹪; β-sitosterol, 36.56%),
phytosterol-3-O-β-D-glucosides (campesterol-3-O-β-D-glucoside
, 14.91%; stigmasterol-3-O-β-D-glucoside, 47.54%; β-sito-
sterol- 3-O-β-D-glucoside,37.55% ) and D-sucrose were
obtained by column chromatography. The structure ofthese
compounds were identified by spectrometric and chemical
methods. All the above compound, except friedlin, were firstly
isolated from the genus of Melanolepis in the literature.
