从昆明山海棠Tripterygium hypoglacum (Levl.)Hutch去皮根中分离得1-表儿茶酸(1-epicatechin)。通过健康成熟小鼠常规的雄性抗生育实验结果表明,1-表儿茶酸的前体粗品:以962mg/kg灌胃雄性小鼠,每d1次,连续15d,停药后第2周与雄鼠交配成功的成
1-epicatechin was isolated from the peeled root of Tripterygium hypoglacum (Levl.) Hutch. The results of conventional male anti-fertility experiments in healthy mature mice showed that crude 1-epicatechin precursor was administered intragastrically to male mice at 962 mg / kg every 15 days for 1 d and for 2 weeks after discontinuation Murine successful mating
