Stephania rotunda

In the course of studies directed towards the structure elucidation of Rotundine from Stephania rotunda LOUREIO, the /3-piperidone 28, which is available starting from the keto ester 27, was treated with mercuric acetate in 10% acetic acid solution. Basification yields the betaine 29 as colorless prisms (Scheme 12). [Pg.82]

A new phenolic base, stepharotine, C21H25O5N (hydrobromide, mp 227°-229° [a]y —203° in MeOH), has been isolated from Stephania rotunda Loureiro, and structure CVII has been proposed for the alkaloid 180). [Pg.110]

The bark of this West Indian tree yielded lupeol and d-sesamine in addition to five quaternary alkaloids, namely, chelerythrine, 1-canadine methochloride, candicine, and d-tambetarine, all isolated as chlorides as well as alkaloid-A (mp 266°-268°), which is not to be confused with alkaloid-A from Stephania rotunda (209). The plant has also been referred to as Z.follis oblongo-ovatis Browne, Z. clavaherculis SW., Z. caribaeum Hitchc., Fagara martinicense Lam. [Pg.506]

The tetrahydroprotoberberine alkaloids with three oxygen substituents located in the ring D have been found in Stephania rotunda (Menisper-maceae) (588). These types of alkaloids will probably be helpful in future chemotaxonomy. [Pg.440]
