C15H20O5 (280.13106700000003)


Psilostachyin is a member of the class of compounds known as ambrosanolides and secoambrosanolides. Ambrosanolides and secoambrosanolides are sesquiterpene lactones from the Ambrosia family, with a backbone derivative of azuleno[6,5-b]furan-2-one (ambrosanolides) or azuleno[4,5-b]furan-2-one (secoambrosanolides). Psilostachyin is slightly soluble (in water) and a very weakly acidic compound (based on its pKa). Psilostachyin can be found in mugwort, which makes psilostachyin a potential biomarker for the consumption of this food product. Psilostachyins are bio-active isolates of Ambrosia psilostachya .

   

Psilostachyin C

1,9-dimethyl-5-methylidene-3,14-dioxatricyclo[8.4.0.0²,⁶]tetradecane-4,13-dione

C15H20O4 (264.13615200000004)


Psilostachyin c is a member of the class of compounds known as ambrosanolides and secoambrosanolides. Ambrosanolides and secoambrosanolides are sesquiterpene lactones from the Ambrosia family, with a backbone derivative of azuleno[6,5-b]furan-2-one (ambrosanolides) or azuleno[4,5-b]furan-2-one (secoambrosanolides). Psilostachyin c is practically insoluble (in water) and an extremely weak basic (essentially neutral) compound (based on its pKa). Psilostachyin c can be found in mugwort, which makes psilostachyin c a potential biomarker for the consumption of this food product.

(3R,3aR,4R,9aS,9bS)-4-hydroxy-9-(hydroxymethyl)-3,6,9a-trimethyl-2H,3H,3aH,4H,5H,7H,9aH,9bH-azuleno[4,5-b]furan-2,7-dione

C16H20O5 (292.13106700000003)


11b,13-dihydrolactucin is slightly soluble (in water) and a very weakly acidic compound (based on its pKa). 11b,13-dihydrolactucin can be found in a number of food items such as endive, chicory, dandelion, and romaine lettuce, which makes 11b,13-dihydrolactucin a potential biomarker for the consumption of these food products.
