Abstract
Flavonoid compositions in the leaves of 24 Diospyros species were surveyed by HPLC for chemotaxonomic purpose.
The species analyzed include D.areolata, D. castanea, D.buxifolia, D.confertiflora, D.decandra, D.discolor, D.ehretioides, D. glandulosa, D.gracilis, D.malabarica var. siamensis, D.mollis, D.montana, D. pyrrhocarpa, D.rhodocalyx, D.sandwicensis, D.sumatrana, D.toposia, D.variegata, and D.wallichii, all for tropical and subtropical origin, and D.lotus, D.oleifera, D.kaki, D. rhombifolia and D.virginiana, for temperate origin.
Among these species, D.areolata, D. castanea, D.confertiflora, D.gracilis, D.malabarica var. siamensis, D.pyrrhocarpa, D. toposia and D.variegata showed no peak for flavonoids by HPLC, while the others had 1 to 10 peaks.
Species native to temperate regions had more peaks than those native to tropical and subtropical regions.
When cluster analysis by UPGM was done based on dissimilarities of these peaks, temperate species showed close relationship to each other, except for D.rhombifolia. D.glandulosa, which is supposed to be closely related to D.kaki by its similarity in morphology, could not show a close relationship to D.kaki in the present study.
