概要

HPLC analysis and yield of oleanene-glucuronide(OG)was done on some commercially available edible beans:seeds of Glycine max, Glycine max cv.Kuromame, Phaseolus vulgaris cv.Torosuku, Phaseolus vulgaris cv.Toramame, Phaseolus vulgaris cv.Taishokintoki, Phaseolus coccineus cv.Ooshirobana, Phaseolus coccineus cv.Murasakihanamame, Vigna unguiculata cv.Chuguro, Vigna angularis cv.Dainagon, Arachis hypogaea, Pisum sativum, and Vicia faba.All the beans listed above have OG, though in varying the amounts.Furthermore the HPLC profiles of beans belonging to the same genus were very similar except for that of the Vigna genus.There was no great difference of the HPLC profiles with respect to the cultivated varieties.The structures of the major OGs in each type of beans were identified as soyasaponins I(1)and V(2), and phaseoside I(3)(Phaseolus vulgaris and P.coccineus);1 and soyasaponin II(4)(Glycine max);1 and 2(Vigna unguiculata);1(Pisum sativum, Arachis hypogaea and Vicia faba).In contrast, those in Dainagon(Vigna angularis cv.Dainagon)were identified as azukisaponins II(5)and VI(6).
