New Triterpene Constituents, Foliasalacins A<sub>1</sub>&mdash;A<sub>4</sub>, B<sub>1</sub>&mdash;B<sub>3</sub>, and C, from the Leaves of <i>Salacia chinensis</i>
Four dammarane-type, three lupane-type, and an oleanane-type triterpenes named foliasalacins A(1) (1), A(2) (2), A(3) (3), A(4) (4), B(1) (5), B(2) (6), B(3) (7), and C (8) were isolated from the leaves of Salacia chinensis LINN. collected in Thailand. The structures of newtriterpene constituents (1-8) were characterized on the basis of chemical and physiochemical evidence.

gymnosporic acid, 3β-hydroxy-(20 R )-lupan-29-oic acid, wallichianic acid, 3β-hydroxy-(20 S )-lupan-29-oic acid and a new diol wallichianol, (20 S )-lupane-3β,29-diol have been isolated fromGymnosporiawallichiana , in addition to β-amyrin, friedelin, 3β-hydroxy-29-norlupan-20-one and dulcitol.
摘要 两种新的差向异构三萜酸、裸孢子酸、3β-羟基-(20 R )-lupan-29-oic酸、wallichianic酸、3β-羟基-(20 S)-lupan-29-oic酸和一种新的二醇wallichianol, (20 S )-lupane-3β,29-diol 已从 Gymnosporia wallichiana 中分离出来,此外还有 β-amyrin、 Friedelin、3β-hydroxy-29-norlupan-20-one 和 dulcitol。
