1-Deoxynojirimycin

1-Deoxynojirimycin (DNJ) is an alpha-glucosidase inhibitor, most commonly found in mulberry leaves. Although it can be obtained in small quantities by brewing an herbal tea from mulberry leaves, interest in commercial production has led to research on developing mulberry tea higher in DNJ, and on alternate routes of production, such as via Bacillus species.
