A new kaempferol glycoside, kaempferol-3-O-beta-D-glucopyranoside-7-O-alpha-L-arabinofuranoside (1), was isolated from the EtOH extract of Pyrrosiapetiolosa together with six known flavonoids already reported from the same plant. Structural elucidation was performed by means of physico-chemical methods including MS, and 1D and 2D NMR spectroscopy.
从石韦乙醇提取物中分离得到一种新的山柰酚苷，即山柰酚-3-O-β-D-吡喃葡萄糖苷-7-O-α-L-阿拉伯呋喃糖苷（1），同时还分离出该植物中已报道的六种已知黄酮类化合物。通过质谱、一维和二维核磁共振光谱等物理化学方法进行结构解析。
