白冇樹[Melanolepis multiglandulosa],為大戟科( Euphorbiaceae )
蟲屎屬( Melanolepis )之植物,是落葉性灌木,本植物為單屬種。文獻
上記載白冇樹植物的根部有袪風、利水、消炎之功效,主治下消、跌打傷
。樹皮及葉微熱之,在菲律賓外敷為發汗劑。本研究由白冇樹根部的甲醇
萃取液中,分離得到下列幾個化合物 oleano- lic 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 混晶
, 5α-stigmast-3,6-dione, phytosterols ( campesterol, 11.44%;
stigmasterol, 52.00﹪; β-sitosterol, 36.56% ), phytosterol-3-O-
β-D-glucosides (campesterol-3-O-β-D-gluco- side, 14.91%;
stigmasterol-3-O-β-D-glucoside,47.54%; β-sito- sterol- 3-O-β-
D-glucoside,37.55% ), D-sucrose, friedelin 等化合物,並經由光
譜分析及化學方法確定其結構。以上化合物除 friedelin外,均為白冇樹
成分首次報導。

Melanolepis multiglandulosa (Reinw.) Reichb. f. et Zoll.
(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.
