illigera rhodantha/alkaloid

Three undescribed aporphine alkaloids laurodionine B (1), illigerine A (2), and N-formyl-laurolitsine (3) were isolated from the methanolic extracts of the Chinese medicinal plant, Illigera aromatica, together with three known analogues (4-6). The chemical structures of 1-6 were identified by

Three new monoterpene phenylpropionic acid esters, illigerates A-C (1-3), and one new aporphine alkaloid, illigeranine (4), as well as four known ones, actinodaphnine (5), nordicentrine (6), 8-hydroxy carvacrol (7), and 3-hydroxy-α,4-dimethyl styrene (8), were isolated from the tubers of Illigera

Six aporphine alkaloids, (+)-(S)-N-butyrylcaaverine (1), (+)-(S)-N-propionylcaaverine (2), (+)-(S)-N-acetylcaaverine (3), (+)-(6aR,7R)-N-butyrylnorushinsunine (4), (+)-(6aR,7R,E)-N-(but-2-enoyl)norushinsunine (5), and N-formyldehydrocaaverine (6) were isolated from the roots of Illigera luzonensis,

A new dibenzopyrrocoline alkaloid, (-)-grandifloramine (1), together with five known ones, actinodaphnine (2), N-methyllaurotetanine (3), boldine (4), lindcarpine (5), and (+)-norboldine (6), were isolated from Illigera grandiflora W. W. Sm. et J. F. Jeff. The structure of 1 was identified by

Using antiplatelet aggregation as a guide to fractionation, seven aporphines, actinodaphnine (1), N-methylactinodaphnine (2), launobine (3), dicentrine (4), O-methylbulbocapnine (5), hernovine (7), and bulbocapnine (9), and two oxoaporphines, dicentrinone (6) and liriodenine (8), were isolated from

Illigera henryi, an endemic traditional Chinese medicine, contains abundant aporphine alkaloids that possess various bioactivities. In the present study, tubers of I. henryi were fermented by several fungi, and the acetylcholinesterase (AChE) inhibitory activities of non-fermented and fermented I.

Phytochemical investigation of the roots and stems of Illigera luzonensis afforded two new aporphine alkaloids (1) and (2), one new bisdehydroaporphine alkaloid (3), and one new benzenoid (4), along with 28 known structures. The structures of new compounds were elucidated by spectral and MS

Illigera aromatica S. Z. Huang et S. L. Mo and Illigera henryi W. W. Sm., belonging to the genus Illigera (Hernandiaceae), are used as herbal medicines for promoting blood circulation and treating tuberculosis. Actinodaphnine, the major bioactive alkaloid, plays an important role in the quality
