カイコガ幼虫のα-グルコシダーゼ阻害活性における系統間差異 The differences in α-glucosidase inhibitory activities among several strains of the silkworm, Bombyx mori
The difference in <B>α</B>–glucosidase inhibitory activities among several strains of the silkworm, <I>Bombyx mori</I> which were reared in Tokyo University of Agriculture and Technology was discussed. The inhibitory activity of silkworm (Koishimaru; 5 th instar larvae) was significantly higher (p<0.01) than that of mulberry leaves (Minamisakari) which was used as feed. The inhibitory activity of silkworm powder was also significantly higher (p<0.01) than that of mulberry powder. The inhibitory activities of eight strains of the silkworm were measured. The inhibitory activity of Koishimaru (4 th instar larvae) was higher than those of other strains of larvae in 4 th and 5 th instar. Furthermore, between the same strains, we found that the inhibitory activity of 4 th instar larvae was higher than that of 5 th instar expect Aburako. On the other hand, we also investigated the <B>α</B>–glucosidase inhibitory activities at different stages in C 108 and J 601 strain. 3 rd instar larvae of C 108 was significantly higher (p<0.01; 2 rd; < 0.05) than other instar larvae and pupa. 3 rd instar larvae of J 601 was also higher (4 th; p<0.05; 5 th; p<0.01) than 4 th and 5 th instar larvae.
