Lipolytic effect of compounds isolated from leaves of mulberry (<i>Morus alba</i> L.) in 3T3-L1 adipocytes

Abstract

In this study, 19 known compounds were isolated from mulberry (Morus alba L.) leaves. The lipid accumulation inhibitory activity of the isolated compounds was investigated. Compounds 4 and 12 showed good anti-adipogenic activity based on 3T3-L1 adipocytes with values of 36.6 ± 9.0 and 34.7 ± 4.0%, respectively. In addition, compounds 3, 6 and 15 showed significant inhibitory activity with values from 15.4 to 21.2% and compounds 2, 8-9 and 17-18 exhibited weak activity with values ranging from 2.1 to 10.7% at a concentration of 40.0 μM. These results show the potentiality that mulberry leaf is an excellent inhibitory phytochemical source against lipid accumulation.
