This study was carried out to investigate the protective effect of Red Ginseng Saponins on 2,3,7,8-Tetrachlorodibenzo-p-dioxin (TCDD) induced toxicities in guinea pigs ($200{\pm}10$ g). Normal control (NC) group guinea pigs ($200{\pm}10$ g) received vehicle and saline, while the TCDD-treated (TT) group was given water-extract (WE), saponin fraction (SF) and non-saponin fraction (NSF). Korean red ginseng fractions were administered from 1 week before TCDD-exposure for 4 weeks. Body weight loss and deteriorated clinical parameters related to sugar metabolism and liver function such as lipase and AST, respectively, these were significantly reduced by both saponin and non-saponin fractions. However, increase of lipase was attenuated by the saponin fraction in a dose-dependent manner. Only AST was affected by the saponin fraction. The results suggest that saponins are active substances in the Korean red ginseng water extract against TCDD induced toxicities in Guinea pigs.

The therapeutic effect of tissue cultured root of mountain ginseng (Panax ginseng) (tcMG) on 2,3,7,8-tetrachlorodaibenzo-p-dioxin (TCDD) induced toxicity in rat was investigated. The rats were assigned into three groups (10 rats/group), control, TCDD exposed group and tcMG treated group after TCDD exposed. $50\;{\mu}g/kg$ of TCDD was injected by i.p. for TCDD exposed group and 30 mg/kg of tcMG saponin was administered for 4 weeks by oral gavage for tcMG treated group. The weights of body, spleen, kidney, thymus, testes and epididymides were decreased in the single TCDD treatment. However these organs was significantly recovered by tcMG saponin except thymus (p<0.05). tcMG decreased the level of hepatic demage maker enzymes, AST and ALP. It also lowered total cholesterol and triglyceride. The level of serum triglyceride was significantly decreased in tcMG saponin treated group compared with the control. Histopathological examination revealed morphological change in the liver spleen, thymus and testes of TCDD treated rats. However they were relatively well preserved in the tcMG treatment group. In conclusion, TCDD induced toxicity was some repaired by tcMG. tcMG may be useful for prevention and treatment of TCDD induced toxicity.
수치에 따른 숙지황 중의 5-hydroxymethyl-2-furaldehyde 함량분석

In order to determine the content of 5-hydroxymethyl-2-furaldehyde (5-HMF) in the Rehmanniae Radix Preparata, 5-HMF was isolated from the EtOAc fraction of the Rehmanniae Radix Preparata samples and identified by spectroscopic and physicochemical evidences. Twenty one samples prepared on the basis of increasing number of stewing times with wine were analyzed by HPLC. From this analysis, it was revealed that the samples processed under one to nine times of stewing showed increasing pattern in 5-HMF contents. And the samples processed under 9 to 18 times of stewing showed 0.53-0.74% in 5-HMF contents. However, for those samples processed more than 19 times, 5-HMF content profile showed decreasing pattern.
