Mexicanolide limonoids from the Madagascan Meliaceae Quivisia papinae.
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.
