An herbicidal composition comprising one or more compounds of Formula I: where Rand Rare H or taken together with the carbon atoms to which the are attached form a furane ring; Rand Reach independently represent H, &#x2014;OH or &#x2014;O&#x2014;(C-C) alkyl; and Ris H, (C-C) alkyl, &#x2014;(C-C) alkylene-O-glucoside or &#x2014;COOH; and an agriculturally acceptable vehicle. There is also disclosed a method for weed control by application of compounds of Formula I and the use of the composition for controlling weeds.

Herbicidal composition comprising chromone derivatives and a method for weed control

Disclosed are methods of extracting and purifying capsinoids (e.g., capsiate, dihydrocapsiate) fromspecies fruit involving drying (e.g., freeze drying) the fruit to produce dried fruit and grinding the dried fruit to produce powdered fruit, extracting the powdered fruit at least once with a non-polar organic solvent (e.g., pentane, hexane, heptane, iso-octane, cyclohexane) to produce an organic solvent extract, subjecting the organic solvent extract at least once to liquid/liquid extraction (partitioning; no drying involved) using a polar solvent (e.g., acetonitrile, methanol) to form a capsinoid enriched polar solvent partition, and optionally purifying the capsinoid enriched polar solvent partition (e.g., via HPLC using acetonitrile as a carrier) to yield capsinoids. The non-polar organic solvent is not miscible with the polar solvent.
