Chalcones (1, 3-diaryl-2-propen-1-ones) are open chain flavonoids that are widely
biosynthesized in plants. They are important for the pigmentation of flowers and, hence, act …

(αR)-3′-C-β-d-xylopyranosyl-α, 3, 4, 2′, 4′-pentahydroxydihydrochalcone, and (αR)-3 …

Chalcones are plant-derived polyphenolic compounds commonly found in edible plants
such as tomatoes, apples, licorice, and fingerroot. The molecular structure of two aromatic …

A new prenylated chalcone xanthohumol M (1), a novel prenylated bichalcone humulusol

Diarylheptanoids, natural products with a 1, 7-diphenylheptane structural skeleton, are
mainly distributed in the roots, rhizomes and bark of Alpinia, Zingiber, Curcuma and Alnus …

Chalcones have a three-carbon α, β-unsaturated carbonyl system composed of two phenolic
rings. Many chalcones have shown broad spectrum of biological activities with clinical …
