| Abstract: | An investigation of the seeds of the Madagascan Meliaceae Quivisia papinae has yielded five mexicanolide group limonoids, together with two known mexicanolide limonoids and two known triterpenoids. Quivisianolide A 9 possesses a hitherto unreported 9alpha,11alpha-epoxide ring, quivisianolide B 10 the corresponding delta(9(11)) double bond, and quivisianone 11 is a 17-keto seco-ring D compound. |
