Spiroschincarins A-E (1-5), five novel spirocyclic schinortriterpenoids featuring a unique 1-oxaspiro[6.6]tridecane motif, were isolated from the fruit of Schisandra incarnata. Their structures with absolute configurations were determined by extensive spectroscopic analyses, single-crystal X-ray diffractions, and experimental ECD (electronic circular dichroism). A hypothetical biogenetic pathway of 1-5 was postulated.
五味子甲素 - E（1-5），五种新型的螺环环樟烯三萜类化合物，具有独特的 1-氧螺[6.6]十三烷母核，从五味子的果实中分离得到。通过广泛的光谱分析、单晶 X 射线衍射和实验 ECD（电子圆二色性）确定了它们的结构和绝对构型。提出了 1-5 的假设生物合成途径。
