被子植物におけるgalactosyl ononitolおよびononitolの分布

抄録

1 D-5-O-(α-D-Galactopyranosyl)-4-O-methyl-myo-inositol and 4-O-methyl-myo-inositol were found in seeds of four leguminous species of three genera [Cassia obtusifolia L., Vigna angularis Ohwi et Ohashi, Vigna unguiculata Walp. and Lablab purpureus Sweet] out of ca. 60 examined species from 20 families. However, these low-molecular weight carbohydrates were not detected in two other species from the above genera [Cassia mimosoides L. subsp. nomame Ohashi and Vigna mungo Hepper]. These inositol derivatives were also not found in two species of Phaseolus, which is regarded as being more closely related to Vigna than Lablab.
