Résumé
Many kinds of effective compounds are contained in vegetables. Particularly, lipid is a necessary substance for plants and animals to keep in satisfactory condition to sustain their lives. In general, plants biosynthesize many kinds of effective fatty acids and sterols as lipid, compared with animals. This paper can be summarized as follows ; (1)The content of palmitic acid, linolic acid, sitosterol, campesterol and cholesterol in seed oils of cacti are correlated with evolution of cacti. Especially, it was detected that the content of cholesterol in Cactoideae is less than that of Opuntioideae. (2)Two unusual fatty acids ; cis-9, trans-11, trans-13, cis-15-octadecatetraenoic acid(α-parinaric acid) and cis-9,trans-14,octadecadien-,12-ynoic acid (dehydrocrepenic acid) were detected in the fatty acid components of C. cristata. In the seeds of I. balsamina large amount of α-parinaric acid is contained. It is the first discovery of α-parinaric acid detected from fungi. While dehydrocrepenic acid is contained in Clavulinaceae and Cantharel-laceae, it is not contained in Ramariaceae and Gomphaceae. In addition, brassicasterol was detected in common as a sterol component of Ascomycetes. In general, Brassicaceae contains a large amount of brassicasterol, it was not detected in fungi. It is the first discovery ofbrassicasterol detected from fungi. These results suggest that dehydrocrepenic acid and brassica-sterol are applied for classification of fungi because their forms are simi
