phellodendrine/phellodendron amurense

Previously we have isolated the quaternary base alkaloids, magnoflorine and phellodendrine, from Phellodendri Cortex (cortex of Phellodendron amurense Rupr., Rutaceae) as the biologically active principles to suppress local graft-versus-host (GvH) reactions in mice. In this paper, we focus on

We previously reported that Wen-Qing-Yin (Unsei-in), a traditional Chinese blended medicine, inhibited the induction phase of various kinds of delayed type hypersensitivity (DTH) and local graft-versus-host (GvH) reactions, but did not affect humoral immune responses or the effector phase of DTH in

Alkaloids from Cortex Phellodendron amurense Rupr. were identified to determine the material basis for the bioactivity of this herb. HPLC-ESI-MS with photodiode array detection coupled to XCharge C18 column was applied to analyze the alkaloids qualitatively and quantitatively. A total of 37

A total of 31 commercial samples of Phellodendri cortex (Rutaceous plant) which originated from PHELLODENDRON AMURENSE Ruprecht, P. CHINENSE Schneid, P. WILSONII Hayata et Kanehira, and P. AMURENSE Rupr. var. SACHALINENSE Fr. Schm., respectively, were collected from the Taiwan and Japan herbal

In the present research, 674 wild medicinal material samples of Phellodendri amurensis Cortex were collected from 31 sampling sites in the whole distribution of its original plant Phellodendron amurense. The samples were collected under the premise that the stem diameter of sampling plant, sampling
