Limonin, is a limonoid, and a bitter, white, crystalline substance found in citrus and other plants. It is also known as limonoate D-ring-lactone and limonoic acid di-delta-lactone. Chemically, it is a member of the class of compounds known as furanolactones. Ongoing research programs are examining the effects of limonin in human diseases. Citrus seed extracts reportedly have antiviral properties, inhibiting replication of retroviruses like HIV-1 and HTLV-I. Neuroprotective effects of limonin have also been described. Limonin reduces proliferation of colon cancer cells and has been tested as an anti-obesity agent in mice.

How to use

In Vitro:

Limonin is a furanolactone enriched in citrus fruits, which has antivirus and antitumor ability. Limonin inhibits the replication of human immunodeficiency virus-1 (HIV-1) in culture of human peripheral blood mononuclear cells (PBMC) with an EC50 of 60 μM. Limonin also shows antinociceptive and anti-inflammatory effects in vivo. Limonin is a potent anti proliferative agent against human hepatoma HepG2 cells via regulation of apoptosis and Wnt signallings.
