The ether-soluble neutral constituents of the dried roots of Trichosanthes japonica REGEL, Trichosanthes kirilowii MAXIM. and Trichosanthes cucumeroides MAXIM. were examined. Mixed glycerides, Δ7-stigmastenol (IV), α-spinasterol (V), steryl (mixture of Δ7-stigmastenol and α-spinasterol)-β-D-glucopyranoside (VI, VII) and steryl (mixture of Δ7-stigmastenol and α-spinasterol)-6'-fatty acyl (mixture of palmitic acid and (Z, Z)-9, 12-octadecadienoic acid)-β-D-glucopyranoside (VIII, IX, X, XI) were identified.
Aus der Rinde von Albizzia zygia (Mimosaceae) wurden Lupen‐20(30)‐3β‐ol (1), 14α‐Stigmast‐5‐en‐3β‐ol (3) und5α‐Stigmast‐7,22‐dien‐3β‐ol (5) isoliert, die Blätter enthalten zusätzlich 1‐Glykosid und vier weitere, mit SbCl3‐Reagens anfärbbare Substanzen.
合欢树(含羞草科)的树皮变成羽扇豆-20(30)-3β-ol(1)、14α-柱头-5-en-3β-ol(3)和5α-柱头-7,22-二烯-3β- Ol (5) 分离后,叶子中还含有 1-糖苷和其他四种可以用 SbCl3 试剂染色的物质。
Co-occurrence of chondrillasterol and spinasterol in two cucurbitaceae seeds as shown by 13C NMR
Abstract 13 C NMR spectroscopy of the sterols isolated from seeds of bottle gourd ( Lagenaria leucantha var. gourda ) and water melon ( Citrullus battich ) has demonstrated the co-occurrence of the C-24 epimers spinasterol and chondrillasterol.
摘要 从葫芦 ( Lagenaria leucantha var. gourda ) 和西瓜 ( Citrullus battich ) 种子中分离出的甾醇的 13 C NMR 光谱证明了 C-24 差向异构体菠菜甾醇和软骨甾醇的共存。
