慈溪麦冬甙A和B的结构

摘要/Abstract

摘要： 从浙江慈溪产中药麦冬(Ophiopogon japonicum)中分离得到2个新的C27甾体甙—慈溪麦冬甙A(2)和B(3)以及已知甙ophiogenin 3-氧-α-L-鼠李糖(1→2)-β-D-葡萄糖吡喃甙(1)。根据光谱和化学证据推定2个新化合物的结构为ophiogenin 3-氧-α-L-鼠李糖吡喃基(1→2)［β-D-木糖吡喃基(1→3)］-β-D-葡萄糖吡喃甙(2)和ophiogenin 3-氧-α-L-鼠李糖吡喃基(1→2)［β-D-木糖吡喃基(1→3)][β-D-葡萄糖吡喃基(1→4)］-β-D-葡萄糖吡喃甙(3).

Abstract: Two new C27 steroidal glycosides nominated cixi-ophiopogon A (2) and B(3) together with a known ophiogenin 3-O-α-L-rhamnopyranosyl(1→2)-β-D-glucopyranoside(1)were isolated from the tubers of famous traditional Chinese herb-Ophiopogon japonicum.The spectroscopic and chemical evidences revealed their structures to be ophiogenin 3-O-α-L-rhamnopyranosyl(1→2)［β-D-xylopyranosyl(1→3)］-β-D-glucopyranoside(2) and ophiogenin 3-O-α-L-rhamnopyranosyl(1→2)［β-D-xylopyranosyl(1→3)][β-D-glucopyranosyl(1→4)］-β-D-respectively(3).
