From: Multilayered regulation of secondary metabolism in medicinal plants
Chemical structure examples of secondary metabolites produced by medicinal plants. Plants yield a wide variety of active ingredients that are identified and isolated. Compounds are organized in accordance with their biosynthesis pathways. The group of phenolic compounds consists of (1) salvianolic acids from Salvia Miltiorrhiza; (2) xanthohumol from Humulus lupulus; (3) scutellarin from Erigeron breviscapus; and (4) baicalein from Scutellaria baicalensis. The group of terpenoid compounds consists of (1) ginsenosides from Panax ginseng; (2) cucurbitacin IIa from Hemsleya chinensis; (3) artemisinin from Artemisia annua; and (4) mogroside V from Siraitia grosvenorii. The group of alkaloid compounds consists of (1) vincristine from Catharanthus roseus; (2) morphine from Papaver somniferum; (3) vincamine from Vinca minor; (4) berberine from Berberis vulgaris; and (5) taxol from Taxus wallichiana
