Abstract

To select superior medicinal provenances of Cyclocarya paliurus，the geographic variation of flavonoid compounds （kaempferol，quercetin，and isoquercetin） in leaves of one-year-old seedlings of 11 provenances was studied. Flavonoid compounds were measured by HPLC. Statistical analyses，such as variance analysis，correlation analysis were used. Results showed a close relationship existed among the three flavonoid compounds with kaempferol content greater than quercetin and isoquercetin. Flavonoid content in Shexian provenance of Anhui （6.770 mg·g-1） and Ziyuan provenance （6.494 mg·g-1） of Guangxi were higher，whereas Shucheng provenance of Anhui was lowest （1.230 mg·g-1）. Trend surface analysis of geographic variations was made with longitude and latitude being independent variable，the content of flavonoids compounds being induced variable. The kaempferrol showed a center （crossing of 108°E and 27°N）-round variation，with the increase from the center to the west and east ，decrease from the center to the north and south. However，there was no significant trend in the variation of quercetin and isoquercetin. The superior medicinal provenances of Cyclocarya paliurus is Shexian provenance of Anhui and Ziyuan provenance of Guangxi. ［Ch，4 fig. 3 tab. 15 ref.］
