胀果甘草中2个新的二氢黄酮甙

TWO NEW FLAVANONE GLYCOSIDES FROM GLYCYRRHIZIA INFLATA

从胀果甘草（ＧｌｙｃｙｒｈｉｚｉａｉｎｆｌａｔａＢａｔ．）根茎的９５％醇提取部分经ＨＰＬＣ分得两个新的二氢黄酮二糖链甙，经化学和波谱分析，将其结构分别确定为甘草素７ＯβＤ呋喃芹糖４′ＯβＤ吡喃葡萄糖甙（ｌｉｑｕｉｒｉｔｉｇｅｎｉｎ７ＯβＤａｐｉｏｆｕｒａｎｏｓｙｌ）４′ＯβＤｇｌｕｃｏｐｙｒａｎｏｓｉｄｅ（Ｉ）和甘草素７ＯβＤ（３Ｏ乙酰基）呋喃芹糖４′ＯβＤ吡喃葡萄糖甙［ｌｉｑｕｉｒｉｔｉｇｅｎｉｎ７ＯβＤ（３Ｏａｃｅｔｙｌ）ａｐｉｏｆｕｒａｎｏｓｙｌ４′ＯβＤｇｌｕｃｏｐｙｒａｎｏｓｉｄｅ］（Ｉ）。

Two new flavanone glycosides having two chains of sugar moeity were isolated from the roots of Glycyrrhizia inflata Bat by repeated CC and HPLC. They were identified to be liquiritigenin 7 O β D apiofuranosyl 4′ O β D glucopyranoside(I) and liquiritigenin 7 O β D (3 O acetyl) apiofuranosyl 4′ O β D glucopyranoside(II) on the basis of chemical and spectroscopic methods.
