The chemistry of the Vinca alkaloids sitsirikine, catharanthine, and their derivatives

2011
In part I of this thesis are described the structural determinations of sitsirikine, dihydrositsirikine and isositsirikine, three new alkaloids from Vinca rosea Linn. Sitsirikine, C₂₁H₂₆O₃N₂, and dihydrositsirikine, C₂₁H₂₈ O₃N₂, were isolated as an inseparable mixture, which was shown by hydrogenation studies to be comprised of an olefin and its ...

[Analysis of catharanthine content and agronomic traits in Catharanthus roseus].

Zhongguo Zhong yao za zhi = Zhongguo zhongyao zazhi = China journal of Chinese materia medica, 2009
Catharanthine content and agronomic traits in major Catharanthus roseus varieties were analyzed. It was found that there existed great difference in catharanthine content and agronomic traits among the varieties. Catharanthine content was the highest in variety Pacifica Polka Dot (PPD), reaching 3.79 mg g(-1) dry leaf weight, and the lowest in variety ...
