- Abstract
- Two new daphnane-type diterpene esters, daphneresiniferins A (1) and B (2), along with seven known diterpenes, yuanhuacine (3), yuanhuadine (4), yuanhuahine (5), genkwadaphnin (6), genkwanine A (7), genkwanine F (8), and genkwanine H (9), were isolated from the methanol extract of the flower buds of Daphne genkwa. Their structures were elucidated on the basis of spectroscopic methods, especially 2D NMR spectra such as HMQC, HMBC, and NOESY. All the isolates were evaluated for their inhibitory effects of the melanogenesis against alpha-melanocyte stimulating hormone (alpha-MSH)-activated B16 melanoma cells. (C) 2013 Elsevier Ltd.
