A new alloside from Neocheiropteris palmatopedata

A new compound, 2,4,6-trihydroxybenzoic acid 4-O-β-D-allopyranoside (1), together with four known compounds, sucrose (2), fructose (3), ecdysterone (4), and β-sitosterol (5) was isolated from the

Brazilian natural medicines. IV. New noroleanane-type triterpene and ecdysterone-type sterol glycosides and melanogenesis inhibitors from the roots of Pfaffia glomerata.

The ethyl acetate and 1-butanol soluble fractions of the roots of Pfaffia glomerata were found to show inhibitory effects on melanogenesis in theophylline-stimulated B16 melanoma 4A5 cells, and a new noroleanane-type triterpene, pfaffianol A, its glycoside, and ecdysterone-type sterol glycosides were isolated.

Chemical constituents of Silene montbretiana

A new steroidal glycoside was isolated from Silene montbretiana Boiss, a perennial herb growing mainly in the Middle and East Anatolia, Azerbaijan, Iran, and Turkey, and the cytotoxicity against the cancer A549 and Hela cell lines has been evaluated.
