Natural occurrencesEdit

Lupeol is found in a variety of plants, including mango, Acacia visco and Abronia villosa.[1] It is also found in dandelion coffee.

Total synthesisEdit

The first total synthesis of lupeol was reported by Gilbert Stork et al.[2]

In 2009, Surendra and Corey reported a more efficient and enantioselective total synthesis of lupeol, starting from (1E,5E)-8-[(2S)-3,3-dimethyloxiran-2-yl]-2,6-dimethylocta-1,5-dienyl acetate by use of a polycyclization.[3]


Lupeol is produced by several organisms from squalene epoxide. Dammarane and baccharane skeletons are formed as intermediates. The reactions are catalyzed by the enzyme lupeol synthase.[4]


Lupeol has a complex pharmacology, displaying antiprotozoal, antimicrobial, antiinflammatory, antitumor and chemopreventive properties.[5]

Animal models suggest lupeol may act as an anti-inflammatory agent. A 1998 study found lupeol to decrease paw swelling in rats by 39%, compared to 35% for the standardized control compound indomethacin.[6]

One study has also found some activity as a Dipeptidyl peptidase-4 inhibitor and prolyl oligopeptidase inhibitor at high concentrations (in the millimolar range).[7]

It is an effective inhibitor in laboratory models of prostate and skin cancers.[8][9][10]

As an anti-inflammatory agent, lupeol functions primarily on the interleukin system. Lupeol to decreases IL-4 (interleukin 4) production by T-helper type 2 cells.[5][11]

Lupeol has been found to have a contraceptive effect due to its inhibiting effect on the calcium channel of sperm (CatSper).[12]
