Eucommia ulmoides oliv

Du-zhong (Eucommia ulmoides Oliv.) tea is commonly used in Japan in the treatment of hypertension and is thought to be a functional health food. In Japan, statistics published by the Ministry of Health and Welfare show that billions of Japanese yen are spent on Du-zhong each year, ranking Japan at the top in the consumption of this specific health food. According to ancient records,...

The anticomplementary activity of 19 lignoids obtained from the bark of Eucommia ulmoides Oliver (Eucommiaceae) was evaluated by Oshima et al. [27]. (+)-Syringaresinol monoglucoside (42), (+)-medioresinol monoglucoside (eucommin A) (43) and (-)-epipinoresinol (44) were active as inhibitors of the classical pathway (inhibition between 25 and 30%) at a concentration of 1.5 mg/ml or about 3 pM. 

An iridoid isolated from the bark of Eucommia ulmoides Oliv. (Eucommiaceae) genipin (55), showed a stronger anticomplementary activity (i.e. 75.3 1.8% inhibition of the classical pathway at a concentration of 1.5 mg/ml or 6.6 pM) than...
