摘要
继从西藏产茅膏菜(Drosera peltata Smith Var.lunata)中分离得到一个新茚满酮化合物,又分离得到4个单体化合物,经UV,IR,~1H-NMR,^(13)C-NMR,MS 及理化方法等确定了其结构。其中3个为酚(酉安)类化合物,分别为对-羟基苯甲酸(P-Hydroxybenzoic acid,Ⅸ),原儿茶酸(Protocatechuic acid.Ⅹ),没食子酸(Gallic acid,Ⅺ)。另1个为β-谷甾醇(β-Sitos-terol,Ⅻ)。
Four crystalline compo-
unds were isolated from Drosera peltata
Smith var.lunata(Buch-Ham)C.B.Clarke
collected in Tibet.On the basis of spec-
trospic(UV,IR,~1HNMR,^(13)CNMR,MS)
and chemical data,their structures were
identified as p-Hydroxybenzoic acid(Ⅸ),
Protocatechuic acid(Ⅹ),Gallic acid(Ⅺ)
and β-Sitosterol(Ⅻ).Ⅸ,Ⅹ,Ⅺ were
phenolic acid compounds.
