✦ Synopsis

A new furan, E-6-methyl-6-(5-methyl-2-furyl)hep-3-en-2-one (1), was identi®ed in a lavender absolute, in an extract of prunes, in extracts of green and black tea and in an extract of spinach leaves. Its structure was con®rmed by condensation of 2-methylfuran and 3-methylbut-2-enal under acidic conditions, followed by an aldol condensation with acetone. Two related ketones as well as their corresponding alcohols were also prepared. The organoleptic evaluations of all compounds are presented. # 1997

As one of the most promising cancer chemopreventive agents, p-carotene has been studied extensively. However, other natural carotenoids have also suppressed tumorigenesis, and some are more potent than p-carotene. For example, a-carotene shows higher potency than p-carotene in suppressing tumorigene
