摘要
从金铁锁(Psammoslene tunicoides)根中分离到二个新的齐墩果烷型五环三萜皂甙Ⅰ、Ⅱ,经光谱测定和化学降解证明它们的化学结构为齐墩果烷-3α,16α-二羟基-12烯-23-酸-28-O-β-D-葡萄吡喃糖基(1—3)-β-D-葡萄吡喃糖基(1—6)-β-D-葡萄吡喃糖甙(Ⅰ)和齐墩果烷-3α,16α-二羟基-12烯-23-酸-28-O-β-D-葡萄吡喃糖基1—6[-β-D-葡萄吡喃糖基1—3]-β-D-葡萄吡喃糖甙(Ⅱ)。上述两个化合物的母核配基均为同一的物质,差异是糖的连接位置不相同。
Psarnmosilene tunicoidcs W. C. Wu et C. Y. Wu is a famous medical herb in Yunnan province. It is usually used as anodyne and haemastatic. The saponins are abundant in its root and possess physiological activities of analgesia, counteracting inflammation, bactriostasis. Two new oleananc typc-triterpene glucosidcs ⅠandⅡ were isolated. Their structures were determined as 28-β-D-glucopyranosyl( 1-3 )-β-D-glucopyranosyl( 1 -?6 ) -β-D-glucopyra-nosyl-3α, 16α-dihydroxy-12 ene-23-dioie acid and 28-β-D-glucopyranosyl 1 ?6 [-β-D-glucopyranosyl [1-3]-β-D-glucopyransidc-3α, 16α-dihydroxy-l2-enc-23-dioic acid, respectively. The two saponins and their sapogenins are all new natucal comnounds.
