新的环己烯环氧化物(+)- pandooxide和(+)-。-senepoxide和(-)-pipoxide分别从尤瓦属新种U. pandensis的枝、根和叶中分离得到。用光谱学方法测定了它们的结构和立体化学构型。吡氧化物的绝对结构与以前从乌瓦里亚种中分离出来的完全相反。（+）-的绝对立体构型。x射线衍射分析明确地确定了-二氧化二氮。
The new cyclohexene epoxide (+)-pandoxide along with (+)-.beta.-senepoxide and (-)-pipoxide were isolated from the stembark, roots and leaves of the new Uvaria species U. pandensis. Their structures and stereochemical configurations were determined by spectroscopic methods. The pipoxide has an absolute configuration opposite to the one previously isolated from Uvaria species. The absolute stereochemical configuration of (+)-.beta.-senopoxide was assigned unambigously by an X-ray diffraction analysis.
