Some Aloe species are cultivated for their medicinal and
cosmetic properties. In this study, the constituents of three
Kenyan Aloe species, A. kilifiensis; A. lateritia and A.
graminicolla werecharacterized. Anumber of anthraquinones
and pre-anthraquinones were isolated. They included
chrysophanol , aloe saponarin I and II, helminthosporin,
asphodelin, di-aloesaponarin, pre-chrysophanol (L),
aloesaponol I & n, asphodelin-lO-rhamnoside (2), 10-
(chrysophanol-7'-yl)-lO-hydroxychrysophanol-9-anthrone(3).
Compound 2 was obtained for the first time from the genus
Aloe. The structure elucidation and the chemotaxonomic
significance of some of these compounds will be presented.
