Sweet broomweed (Scoparia dulcis) is an edible perennial medicinal herb widely distributed in tropical and subtropical regions of Asia, Africa, and the Americas. Four compounds, (2R)-7-methoxy-2H-1,4-benzoxazin-3(4H)-one 2-O-β-galactopyranoside [(2R)-HMBOA-2-O-Gal], 3,6-dimethoxy-benzoxazolin-2(3H)-one (3,6-M2BOA), 3-hydroxy-6-methoxy-2-benzoxazolinone (3-OH-MBOA), and scutellarein 7-O-β-glucuronamide, along with eight known compounds, including two 7-methoxy-1,4-benzoxazin-3(2H)-one 3-O-hexopyranosides [(2R)-HMBOA-2-O-Glc and (2R)-HDMBOA-2-O-Glc], 6-methoxy-benzoxazolin-2(3H)-one (MBOA), acteoside, sodium scutellarin, p-coumaric acid, and two monosaccharides (fructose and glucose), were isolated from the aqueous extract of S. dulcis. Antiproliferative activities of the six benzoxazinoid compounds against the DU-145 human prostate cancer cell line were assayed, and one of these displayed an IC₅₀ of 65.8 μg/mL.
