Morus alba
Lipase inhibitors can be found naturally in plants and can also be produced as pharmaceutical drugs. Some lipase inhibitors have been identified in "Panax ginseng". Some active compounds with chalcone scaffold found in "Glycyrrhiza glabra", "Cassia mimosoides", "Glycyrrhiza uralensis", "Boesenbergia rotunda", apples and "Morus alba" also had strong effect against lipase. Caffeine, theobromine and theophylline were also supposed as lipase inhibitors although there was still controversial.
