Abstract

Phytochemical investigation of Platytaenia multicaule resulted in the isolation of two new ceramides, N-triacontylpentadecanamide and 1,3,4-trihydroxy-2,dodecanoylamino-(24E)-unacotenene, along with two known compounds, beta-sitosterol and beta-sitosterol glycoside. The structure elucidation of the isolated compounds was based primarily on 1D and 2D NMR analyses, including COSY, NOESY, HMQC, and HMBC correlations.

摘要

对多茎扁囊苔草进行植物化学研究，从中分离出两种新的神经酰胺，即N-三十烷基十五酰胺和1,3,4-三羟基-2-十二烷酰氨基-（24E）-十九碳烯，以及两种已知化合物，β-谷甾醇和β-谷甾醇糖苷。所分离化合物的结构解析主要基于一维和二维核磁共振分析，包括COSY、NOESY、HMQC和HMBC相关分析。
