Methods: The 7 populations were selected randomly from the three floristic zones of Yunnan. Adult plants and infructescences were chosen randomly to gain flower number and fructification percentage per inflorescence, and seed number per fruit. All date was analyzed by SPSS (13.0 version). Results: As A. tsaoko was distributed (or transplanted) from a habitat at lower latitude and/or altitude to a site of higher latitude and/or altitude, the flower number per inflorescence increased, on the contrary, the fructification percentage per inflorescence decreased. The competition for reproductive resource was beneficial to increase flower number and seed production. Conclusions: The habitats in south of the tropic of cancer were favorable to the reproduction of A. tsaoko, which reproductive costs were lower and harvest was higher. Increasing flower number per inflorescence may be a strategy to promote the plant to distribute into alpine habitats for both female and male reproductive success.展开更多

Thein vitro antioxidant activities of the five extracts were evaluated by 2, 2-diphenyl-1-picrylhydrazyl (DPPH) radical and hydroxyl radical (OH-) scavenging assay methods.Results: The five extracts showed different extent of antioxidant activities in vitro, especially the ethyl acetate and dichloromethane fractions.Conclusion: The difference of antioxidant activity of different extracts may be associated with the type and structure of antioxidant components in each fraction of A. longiligulare fruits.展开更多
