The phytochemical investigation of the whole plant of Polygonatum multiflorum resulted in the isolation of two new steroidal glycosides, polmultoside A (4) and polmultoside B (5), along with three known glycosides protobioside (1), protodeltonin (2) and huangjiangsu A (3). The structures of the isolated compounds have been elucidated by extensive 1D (H, C) and 2D (COSY, HSQC, HMBC) NMR spectral data analysis, as well as high-resolution mass determinations.
对黄精全草进行植物化学研究，分离得到两个新的甾体糖苷，即多花黄精苷A（4）和多花黄精苷B（5），以及三个已知糖苷原知母皂苷元（1）、原偏诺皂苷元（2）和黄精素A（3）。通过广泛的一维（H、C）和二维（COSY、HSQC、HMBC）核磁共振光谱数据分析以及高分辨率质谱测定，阐明了所分离化合物的结构。
