A novel anti-HIV alkaloid, drymaritin (1), and a new C-glycoside flavonoid, diandraflavone (2), along with eight known compounds, torosaflavone A, isovitexin, spinasterol beta-d-glycoside, p-hydroxybenzoic acid, p-hydroxybenzaldehyde, cis-p-coumarate, methyl 5-hydroxy-4-oxopentanoate, and
A novel flavonoid glycoside, drymariatin A, was isolated from the whole plants of Drymaria diandra (Caryophyllaceae). By spectroscopic analysis, its structure was elucidated as 6-trans-[2''- O-(alpha-rhamnopyranosyl)]-ethenyl-5,7,4'-trihydroxy-flavone.
