Abstract

The purpose of this study was to screen the testosterone-like activities of eight oriental medicines with an in vitro testosterone compound detection (TCD) system. Distilled water and 80% ethanol, both at 80℃, were used to obtain extracts from Cervus nippon temminck (Nokgaksang), Cynanchum wilfordii (Baeksuo), Lespedeza cuneata (Yagwanmun), Panax ginseng (Hongsam), Smilax china (Toryeong), Taraxacum platycarpum (Mindlre), Tribulus terresteis (Namgase), and Trigonella foenum-graecum (Horopa), and extracts at concentrations of 5, 50, and 500 μg/ml were assessed using the TCD system. The testosterone-like activities of the 80% ethanol extracts were seen to increase with concentration and ranged from 0.9 to 5.0 times higher than those of the negative control; Horopa and Yagwanmun exhibited superior testosterone-like activities, followed by Mindlre and Hongsam at the same concentration. Toryeong and Namgase, on the other hand, showed low activity with Nokgaksang and Baeksuo exhibiting very low levels. Compared with the activities of the positive control (5α-DHT), the 80% ethanol extracts of Horopa and Yagwanmun at a concentration of 500 μg/ml showed higher testosterone-like activities than 10-8 M 5α-DHT. The water extracts showed lower activity levels than the ethanol samples, and the change of activity with concentration was also lower. It was confirmed that the 80% ethanol extracts of Horopa, Yagwanmun, and Mindlre etc. enhance the transcription efficiency of testosterone-related genes and may therefore be useful in developing health food or medicinal treatments for the improvement of male menopausal symptoms.
