Further investigation of Cape aloe led to the isolation of two new 5-m
ethylchromones. Their structures have been established as -7-hydroxy-8
-(3-hydroxyacetonyl)-5-methyl-chromone (2) and onyl-8-(2-furoylmethyl)
-7-hydroxy-5-methylchromone (3) on the basis of spectroscopic data. A
mechanistic hypothesis to account for their occurrence in the drug is
presented.
