从新疆雪莲中分出两种新倍半萜类化合物,一种是3α-OH,11β,13-二氢去氢广木香内酯-8-β-D-葡萄糖苷.它的立体结构不同于以前所报道的类似化合物.另一种为新的倍半萜内酯生物碱,经鉴定为13-脯氨酸取代的二氢去氢广木香内酯.命名为大苞雪莲碱(Involucratine).
Two new sesquiterpene compounds were isolated from Xinjiang snow lotus, one is 3α-OH, 11β, 13-dihydro-dehydrogenolactone-8-β-D-glucoside. Its three-dimensional structure is different. Similar compounds previously reported. The other is a novel sesquiterpene lactone alkaloid identified as a 13-proline substituted dihydro-dehydro-galendrolactone. Named as Insulinate (Involucratine) ).
