By means of a bioassay-oriented fractionation of the CO2 extract of Calendula flowers, the triterpenoids are shown as the most important anti-inflammatory principles of the drug. Among them, the faradiol monoester appears to be the most relevant principle for the activity of the drug, due to its
Eleven tabular and nine ligulate flowers from 15 species of Compositae plants were investigated for their triterpene alcohol constituents. This led to the isolation and identification of 11 triterpene alcohols as follows: heliaol, taraxasterol, psi-taraxasterol, alpha-amyrin, beta-amyrin, lupeol,
The triterpene esters ᴪ taraxasterol-3-O-myristate (1) and arnidiol-3-O-myristate (2) were tested for their ability to protect epithelial intestinal barrier in an in vitro model. Their effects on ROS production and on trans-epithelial resistance were investigated on CaCo-2 cell monolayers both in
