Moscatin (Plicatol, 4-methoxyphenanthrene-2,5-diol) is a diphenyl derivative that can be extracted from Dendrobium nobile Lindl. It inhibits arachidonic acid-induced platelet aggregation, and is able to inhibit Candida albicans virulence and growth by down-regulating the expression of genes such as ERG, HSP, and ALS.
