Phytochemical study of plant species : Phytolacca rugosa, P. icosandra, Cestrum ruizteranianum et Ganophyllum giganteum
2011
Phytochemical analysis of the MeOH/H2O (7:3) of the fruits of Phytolacca rugosa, P. icosandra and Cestrum ruizteranianum, as well as the barks of Ganophyllum giganteum, leaded to the isolation and structural characterization of twenty three (1-23) compounds. From P. rugosa, four (1-4) known triterpenoidal saponins belonging to the serjanic acid series were obtained, all saponins are reported for the first time for P. rugosa. P. icosandra was studied and eight compounds were isolated, two triterpenic acids [spergulagenic acid (5) and epiacetylaleurytolic acid (6)], two lignanes (7) and (8) [8, reported for the first time in Phytolaccaceae], a mixture of steroidal glycosides (9) and (9a), two…
