Rubus coreanus, commonly known as 'red raspberry' is used as a traditional oriental medicine in Korea for the management of diseases such as impotence, spermatorrhea and athsma, and for allergies, in combination with other herbal preparations, in many centuries. We undertook a comparison of the hepatoprotective effect of ethanol extracts of the unripe (UREx) and ripe (RREx) R. coreanus extract against acetaminophen (AAP) induced hepatotoxicity in rats. UREx reduced the elevated alanine aminotransferase (ALP), aspartate aminotransferase (AST), total bilirubin (TB), alkaline phosphatase (AP), lipid peroxide and nitric oxide content which had been increased by AAP administration. UREx also increased the cellular glutathione (GSH) content and induced the glutathione-S-transferase (GST), glutathione peroxidase (GSH-Px) content which had been decreased by AAP. RREx did not exhibit strong hepatoprotective effect or antioxidant activity under the same conditions. The experimental results show that the degree of the ripening of R. coreanus affects the hepatoprotective activity in the AAP-intoxicated rats. These findings of a protective mechanism are supportive evidence for the utility of unripened R. coreanus in traditional medicine for liver ailments.

Geniposide and its related iridoid compounds have been used in traditional herbal medicine for thε treatment of Jaundice hepatic diseases and various inflammatorys. For the purpose to increase trandsdermal absorption, the hydrolyzed products of Gardeniae Furctus were identified and assayed of active ingredients and investigated trandsdermal absorption and anti-inflammatory effects. Geniposide was hydrolyzed to genipin by ${\beta}-glucosidase$ and it was suggested that genipin was more suitable form than geniposide for transdermal absorption by its lipophilic property. Using Franz type diffusion cell and the skin of hairless mouse, the permeation rate of hydrolyzed products and their emulsion preparation were determined. Genipin have more increased absorption ratio through the skin of hairless mouse than geniposide. Also, the emulsion of hydrolyzed products of extracts showed higher permeability than that of nonhydrolyzed preparations. After 9 hours $280.85\;{\mu}g/cm^2$ of genipin was absorbed and $193.52\;{\mu}g/cm^2$ in case of geniposide. The Js of geniposide and genipin were $26.27{\pm}4.11\;{\mu}g/cm^2/hr$ and $40.35{\pm}5.04\;{\mu}g/cm^2/hr$ respectively. After carrageenan injection, the swelling was increased repidly to 24 hr and maintained as plateau. but emulsion group weer reached about 2.5 mL and the swelling decreased successively form 24 hr to 72 hr. The anti-inflammation effects of extracts and hydrolyzed products emulsion were increased with significant difference with control group after 24 hr, 48 hr and 72 hr. In carrageenan induced edema, inhibition of swelling was increased in case of hydrolyzed product emulsion compare with nonhydrolyzed group at 24 hr, 48 hr and 72 hr after swelling. In histological study, the anti-inflammatory effects of hydrolyzed products were remarkable at 48 hr and 72 hr compare with nonhydrolyzed. Hydrolyzed products of Gardeniae Fructus extracts containing genipin would be a suitable preparation to increase the transdermal absorption and anti-inflammatory effects.
