Four new flavonoid glycosides, curcucomosides A–D (1–4), three known flavonoid glycosides, 5–7, and four known diarylheptanoids, 8–11, were isolated from the ethanol extract of the aerial parts of Curcuma comosa. The structures of the new compounds were established as rhamnazin 3-O-α-l-arabinopyranoside (1), rhamnocitrin 3-O-α-l-arabinopyranoside (2), rhamnazin 3-O-α-l-rhamnopyranosyl-(1→2)-O-α-l-arabinopyranoside
四个新的黄酮苷,curcucomosides A-d(1 - 4),三种已知的黄酮苷,5 - 7,以及四个已知的二芳基庚,8 - 11,从地上部分的乙醇提取物中分离得到莪comosa。确定了新化合物的结构,为鼠李糖苷3- O - α - l-阿拉伯吡喃糖苷(1),鼠李糖苷3- O - α - l-阿拉伯吡喃糖苷(2),鼠李糖苷3- O - α - l-鼠李糖吡喃糖基-(1→2)-O - α - l-阿拉伯吡喃糖苷(3)和鼠李糖苷3- O - α - l-鼠李糖吡喃糖基- (1→2)-O - α - l-阿拉伯吡喃糖苷(4)分析和化学反应,而已知化合物的那些则通过与报告值的光谱比较进行鉴定。
