摘要：

Two carotenoid aldehydes isolated from R. viridis (Rhodospirillaceae) were identified as lycopen-20-al (13-cis-.psi.,.psi.-caroten-20-al) and the novel 3,4-didehydro-1,2-dihydrolycopen-20 (or 20'')-al (3,4-didehydro-1,2-dihydro-.psi.,.psi.-caroten-20-al or 3'',4''-didehydro-1'',2''-dihydro-.psi.,.psi.-caroten-20-al). Some extracts contained acetonyl derivatives, probably artifacts produced from the cross-conjugated carotenoid aldehydes and acetone under alkaline conditions. The distribution of cross-conjugated caroten-20-als in photosynthetic bacteria is discussed.
