Two major bisbenzylisoquinoline alkaloids, isotetrandrine and berbamine and three protoberberine type alkaloids berberine, palmatine, and jatrorrhizine were isolated from seeds of Berberis thunbergii DC. Berberine and oxyberberine, which is not present in the seeds, were isolated from the pericarp. Identity of the isolated substances was verified by spectral means (i.r., u.V., and mass spectrom...

Pronuciferine N-oxide (1), a proaporphine N-methyl-N-oxide alkaloid, along with the parent alkaloid pronuciferine (2) were isolated from Berberis coletioides. The structure of the new compound was determined by spectroscopic evidence. Compound 1 is the first naturally occurring proaporphinoid alkaloid with an N-oxide functionality.

A study was planned to investigate the role of aqueous extract from Garlic (Allium sativum), Ginger (Zingiber officinale), Neem (Azadirachta indica) and Berberry (Berberis lycium) fed in-mix for their effect upon growth performance, immunomostimulant and anticoccidial in broilers. Two hundred and fourty chicks were randomly allocated in to four groups A, B, C and D, and further into two subgrou...

Berberine-containing plants are used medicinally in virtually all traditional medical systems, and have a history of usage in Ayurvedic and Chinese medicine dating back at least 3,000 years. Berberine has demonstrated significant antimicrobial activity against bacteria, fungi, protozoans, viruses, helminths and chlamydia. In addition, berberine’s actions include: antagonism of the effects of ch...

rivation of blood flow to the brain, results in the insidious delayed degeneration of specific vulnerable neurons within the hippocampus. Among hippocampal neurons, pyramidal cells of the hippocampal CA1 region are most vulnerable to cerebral ischemia. Death of the CA1 pyramidal cells following cerebral ischemia causes a variety of neurological dysfunction such as depression and memory deficits...

Xanthoceras sorbifolium Bunge has great potential for producing biodiesel. In order to select and evaluate appropriate germplasm to produce biodiesel, we analyzed the genetic diversity of Xanthoceras sorbifolium Bunge germplasm based on morphological traits and simple sequence repeats (SSRs) in this study. Fifty-six germplasm samples were evaluated using nine morphological traits and 23 SSR loc...

Pistacia chinensis Bunge is dioecious. The female and male plants have different economic values. In addition to the large differences in floral organ shape on the outside, the male and female plants also have remarkable differences in ecological adaptability and physiological and biochemical characteristics. Thus, studying whether these differences in biological characteristics between male an...
