Abstract
A new tirucallane-type triterpenoid named 24-epi-piscidinol A (1) has been isolated fromCastela texana (T. & G.) Rose (Simaroubaceae) and determined to have the structure 23R,24R,25-trihydroxytirucall-7-en-3-one by X-ray crystallographic analysis. Crystals of 24-epi-piscidinol A are monoclinic, space groupC2,a=23.84 (3),b=7.012 (7),c=17.35 (2) Å, β=103.46 (2)o. Another triterpenoid piscidinol A (2), crystallizes in the orthorhombic space groupP212121 witha=10.659 (2),b=14.499 (3),c=17.922 (4) Å, β=90°. Two coumarino-lignans, cleomiscosin A and C, were also obtained in the course of this work. This is the first time of isolation of tirucallane-type triterpenoids and coumarino-lignans from the genusCastela.
