千金子中非萜类化学成分的研究

Non-terpenoid Constituents from the Seeds of Euphorbia lathyris

摘要:

从大戟科植物续随子(Euphorbia lathyris L.)的干燥成熟种子千金子中分离得到6个非萜类化合物。通过光谱分析，分别鉴定为金色酰胺醇酯(1)、蔓荆子黄酮(2)、青蒿亭(3)、胡萝卜苷(4)、对羟基苯甲酸(5)、秦皮乙素(6)。其中化合物1~5均为首次从千金子中分离得到。

Abstract:

A newly recorded species of Orchidaceae from China, Bulbophyllum dayanum Rchb. f. is reported. It is distinguished from the others of section Sestochilos (Breda) Benth. & Hook. f. by its inflorescence with 2~5 flowers, sepals and petals with ciliate fringe of silky hairs at edges. Dendrobium menglaense X. H. Jin & H. Li is reduced to D. chrysocrepis Parish & Rchb. f. ex Hook. f. as a synonym, and characterized by solitary flowers with spoon-like lip which are borne on the flattened stem. Images and descriptions of the two species are provided.
