摘要：
Mulberry leaves have been used as the sole food for silkworms in sericulture, and also as a traditional medicine for diabetes prevention. Mulberry leaf components, for example 1-deoxynojirimycin (1-DNJ), inhibit the activity of alpha-glucosidase and prevent increased blood glucose levels, and they are highly toxic to caterpillars other than silkworms. The alpha-glucosidase inhibitory activity of mulberry leaves changes with the season, but it is unknown which environmental conditions influence the alpha-glucosidase inhibitory activity. We investigated in this study the relationship between the alpha-glucosidase inhibitory activity and environmental conditions of temperature and photoperiod. The results demonstrate that low temperatures induced decreasing alpha-glucosidase inhibitory activity, while the induction of newly grown shoots by the scission of branches induced increasing alpha-glucosidase inhibitory activity. These results suggest that the alpha-glucosidase inhibitory activity was related to the defense mechanism of mulberry plants against insect herbivores.
