چکیده

Aconitum kusnezoffii Reichb., one of the earliest recorded toxic species of genus Aconitum, has been used as traditional Chinese medicine and medicinal diet over the last 2500 years to treat heart failure congestion, neuralgia, rheumatism and gout, etc. In the present paper, four water-soluble polysaccharide fractions isolated from the tubers of A. kusnezoffii Reichb. were studied the antioxidant and immunological activities for the first time. In vitro antioxidant assays indicated that fraction WKCP-A had noticeable scavenging activities on DPPH radical, hydroxyl radical, superoxide anion, H(2)O(2) and self-oxidation of 1,2,3-phentriol, ferrous ion-chelating ability and reducing power. Moreover, the in vivo immunological assay exhibited that fractions WKCP-A and WKHP could more significantly enhance splenic lymphocyte proliferation and macrophage phagocytosis than other fractions. Therefore, the water-soluble polysaccharides from A. kusnezoffii Reichb., especially WKCP-A, have the potential to be explored as novel natural antioxidants and immunostimulating agents for using in functional foods or medicine.

Two new diterpenoid alkaloids, beiwusines A and B, from Aconitum kusnezoffii.

Two new atisine-type diterpenoid alkaloids, beiwusine A (1) and B (2), have been isolated from the roots of Aconitum kusnezoffii Reichb. Their structures were established on the basis of spectroscopic data. Beiwusines A and B are the first examples of atisine-type diterpenoid alkaloids having a hydroxyl group at C-1. In addition, one known diterpenoid alkaloid spiramine H (3) has been isolated.

Assessment of genetic characteristics of Aconitum germplasms in Xinjiang Province (China) by RAPD and ISSR markers

Aconitum is a medicinal treasure trove that grows extensively on fertile pastures in Xinjiang Province (China); however, its molecular genetic characteristics are still poorly studied. We studied Aconitum kusnezoffii Reichb., Aconitum soongaricum Stapf., Aconitum carmichaelii Debx. and Aconitum leucostomum Worosch, using random amplified polymorphic DNA (RAPD) and inter-simple sequence repeat (...
