Demethoxyencecalin is a chromene isolated from Helianthus annuus, has antifungal activities[1].
Loliolide
(6S,7aR)-6-hydroxy-4,4,7a-trimethyl-2,4,5,6,7,7a-hexahydro-1-benzofuran-2-one
Loliolide, also known as (3s5r)-loliolide, is a member of the class of compounds known as benzofurans. Benzofurans are organic compounds containing a benzene ring fused to a furan. Furan is a five-membered aromatic ring with four carbon atoms and one oxygen atom. Loliolide is soluble (in water) and an extremely weak acidic compound (based on its pKa). Loliolide can be found in sunflower, tea, and wakame, which makes loliolide a potential biomarker for the consumption of these food products.
Demethoxyencecalin
