目的 通過(guò)棕櫚花蕾水提物對(duì)雌性家兔體內(nèi)激素水平的影響，進(jìn)一步探討其抗生育作用機(jī)制。方法 給健康雌性未孕家兔ip不同劑量的棕櫚花蕾水提物，每天1次，連續(xù)9 d。給藥后分別從耳動(dòng)脈取血，測(cè)定血清中的FT₃、FT₄、雌二醇、孕酮。結(jié)果 與生理鹽水組相比，棕櫚花蕾水提物高劑量組明顯降低家兔血清中FT₃水平、升高孕酮含量，而各劑量組對(duì)FT₄和雌二醇含量無(wú)明顯影響。結(jié)論 棕櫚花蕾水提物能降低家兔血清中FT₃水平，并升高孕酮含量。

Objective To explore antifertility effects by the influence of Trachycarpus fortunei on hormone level in female rabbits. Methods To test the level of estradiol, progesterone and thyroid hormone by Elecsys 2010 after intraperitoneal injection of palm buds. Results FT₃ was reduced and progesterone was increased obviously by high dose of AEPB. Three doses of AEPB have no effects on FT₄ and estradiol. Conclusion Aqueous extract of palm buds have the effects of reducing FT₃ and increasing progesterone.
