OBJECTIVE Evaluation of the Sophora alopecuroides var. alopecuroides seed effects on morphine withdrawal syndrome in mice and determination of the alkaloid composition of the seed total extract. METHODS The effects of the seed total extract, alkaloid fraction and major compound matrine on the mice

Seven alkaloids were isolated from the seed of Sophora alopecuroides and identified to be oxymatrin, oxysophocarpine, cytisine, matrine, sophocarpine, sophoridine and nicotine respectively by comparing chromactographic and spectral characteristics with authentic known compounds. Nicotine was

Lysine decarboxylase (LDC) catalyzes the first-step in the biosynthetic pathway of quinolizidine alkaloids (QAs), which form a distinct, large family of plant alkaloids. A cDNA of lysine/ornithine decarboxylase (L/ODC) was isolated by differential transcript screening in QA-producing and
