  日期：2018.5

  New steroidal glycoside 1 was isolated by fractionating total extracted substances from Allium porrum. Its structure was determined as (25R)-5_-spirostane-3β,6β-diol-2,12-dione 3-O-β-D-glucopyranosyl-(1→3)-β-D-glucopyranosyl-(1→2)-[β-D-xylopyranosyl-(1→3)]-β-D-glucopyranosyl-(1→4)-β-Dgalactopyranoside} using chemical transformations, physical constants, and spectral data.

  Four triterpenoid prosapogenins tentatively named CP1, CP3, CP4 and CP5 were isolated from the alkaline hydrolysate of the crude saponin obtained from the root of Clematis chinensis OSBECK. On the basis of chemical and physicochemical evidence, they were characterized as follows : CP1 (I), hederagenin 3-O-α-L-arabinopyranoside ; CP3 (II), oleanolic acid 3-O-β-D-xylopyranosyl-(1→3)-α-L-rhamnopyranosyl-(1→2)-α-L-arabinopyranoside ; CP4 (VI), oleanolic acid 3-O-β-D-xylopyranosyl-(1→3)-α-L-rhamnopyranosyl-(1→2)-α-L-arabinopyranoside ; CP5 (VIII), hederagenin 3-O-β-D-xylopyranosyl-(1→3)-α-L-rhamnopyranosyl-(1→2)-α-L-arabinopyranoside.

  从紫葳根获得的粗皂苷的碱性水解液中，初步鉴定出四种三萜类前皂苷，分别命名为CP1、CP3、CP4和CP5。根据化学和物理化学证据，对其进行了如下表征：CP1 (I)，海都有糖苷3-O-α-L-阿拉伯呋糖苷；CP3 (II)，愈创木酸3-O-β-D-木糖苷-(1→3)-α-L-鼠李糖苷-(1→2)-α-L-阿拉伯呋糖苷；CP4 (VI)，愈创木酸3-O-β-D-木糖苷-(1→3)-α-L-鼠李糖苷-(1→2)-α-L-阿拉伯呋糖苷；CP5 (VIII)，海都有糖苷3-O-β-D-木糖苷-(1→3)-α-L-鼠李糖苷-(1→2)-α-L-阿拉伯呋糖苷。

  A new flavone glycoside (A) m.p. 265-268 ºC, m.f. C33H40O21, [M]+ 742 (FABMS), has been isolated from stem of Taraxacum oficinale (L.) Weber. It was characterized as 3,5,7,3,4-pentahydroxy 8-C methyl flavone 7-O-b-D-xylopyranosyl (1®4)O-b-D glucopyranosyl 3-O-a-L-rhamnopyranoside alongwith known compound ladanein B by various chemical degradations and spectral analysis.
