Colubrina texensis

Colubnnol and colubrinol acetate arc isolated from Colubrina texensis Gray (Rhamnaceae) along with maytanbutine. Colubrinol is also isolated from Trewia nudiflora (Euphorbiaceae). The structures for colubrinol and colubrinol acetate were established by high resolution ms and the comparison of tlieir nmr spectra with that of the known maytanbutine. [Pg.109]

Hovenia dulcis and H. tomentella have been shown to elaborate the new alkaloids hovenine A and hovenine B in addition to the known frangulanine. Hovenine A has been shown to be iV-desmethylfrangulanine (45) on the basis of chemical correlation with frangulanine. The structure of hovenine B has not been defined. Texensine, isolated from Colubrina texensis, has been assigned structure (46),... [Pg.275]
