Abstract
A new sesquiterpene and twelve known compounds comprising eight flavonoids and four terpenoids, were isolated from the leaves, stems, roots and exudate of Croton muscicarpa Muell.. Arg.. Their structures were identified as the terpenoids 6{alpha}-methoxy-cyperene, dammaradienol, squalene, acetyl aleuritolic acid and spathulenol, and as the flavonoids retusin, 3,7,4'-trimethoxy kaempferol, ombuine, pachipodol, kaempferol, casticin, 5-hydroxy-3,6,7,4'-tetramethoxyflavone and artemetin. All isolated compounds were characterized based on IR, MS, {sup 1}H and {sup 13}C NMR, including 2D analyses (COSY, HSQC, HMBC, NOESY) and comparison with data from the literature. (author)
