In this study, the aphrodisiac activities of Crocus sativus stigma aqueous extract and its constituents, safranal and crocin, were evaluated in male rats. The aqueous extract (80, 160 and 320mg/kg body wt.), crocin (100, 200 and 400mg/kg body wt.), safranal (0.1, 0.2 and 0.4ml/kg), sildenafil (60mg/kg body wt., as a positive control) and saline were administered intraperitoneally to male rats. Mounting frequency (MF), intromission frequency (IF), erection frequency (EF), mount latency (ML), intromission latency (IL) and ejaculation latency (EL) were the factors evaluated during the sexual behavior study. Crocin, at all doses, and the extract, especially at doses 160 and 320mg/kg body wt., increased MF, IF and EF behaviors and reduced EL, IL and ML parameters. Safranal did not show aphrodisiac effects. The present study reveals an aphrodisiac activity of saffron aqueous extract and its constituent crocin.
在本研究中,对雄性大鼠评估了藏红花柱头水提取物及其成分藏红花醛和藏花素的壮阳活性。将水提取物(80、160和320mg/kg体重)、藏花素(100、200和400mg/kg体重)、藏红花醛(0.1、0.2和0.4ml/kg)、西地那非(60mg/kg体重,作为阳性对照)和生理盐水腹腔注射给雄性大鼠。在性行为研究中评估的因素包括爬跨频率(MF)、插入频率(IF)、勃起频率(EF)、爬跨潜伏期(ML)、插入潜伏期(IL)和射精潜伏期(EL)。所有剂量的藏花素以及提取物,尤其是160和320mg/kg体重剂量,均增加了MF、IF和EF行为,并降低了EL、IL和ML参数。藏红花醛未显示出壮阳作用。本研究揭示了藏红花水提取物及其成分藏花素的壮阳活性。
