Abstract

A new chromone, 5-hydroxy-2-methoxy-6,7,8-trimethylchromone (1), along with ten known compounds including 5,7-dimethoxychromone (2), 5-hydroxy-7-methoxychromone (3), 5-hydroxychromone (4), 5,7-dihydroxy-2,6-dimethylchromone (5), 5,7-dihydroxy-2,8-dimethyl-chromone (6), 5,7-dihydroxy-2,6,8- trimethylchromone (7), (3S,4R)-4-hydroxymellein (8), (3S,4S)-4-hydroxymellein (9), 4-hydroxymethyl-3,5-dimethyldihydro-2-furanone (10), and 3,4-dihydroxy-3-methyldihydro-2-furanone (11), were isolated from the roots of Haworthia cooperi var. truncata (Asphodelaceae). The structure of the new chromone derivative was elucidated by chemical and physical evidence.
