Dandelion phenolic acid has certain inhibitory effects on Staphylococcus aureus, Bacillus subtilis, Escherichia coli and Salmonella.
4. Terpene alcohols
Taraxadol is a triterpenoid pentacyclic compound with a wide range of sources. The triterpenoid components isolated from medicinal dandelion roots include taraxanthinol, pseudotaraxanthol acetate, taraxatrol, stigmasterol, sitosterol, balsamic resin and other compounds. After roasting dandelion roots, the content of terpene alcohols increased and the content of vitamins and proteins decreased. This shows that taraxanol has certain stability.
5. Trace elements
In addition to the above active substances, 66 trace elements were detected in dandelion. Among them, 5 kinds are necessary for the human body, divided into
Specifically Cu, Zn, Fe, Mn, Mo. It is worth noting that the content of selenium in dandelion is high, and selenium has anti-tumor, antioxidant, anti-aging and other effects.
