They encompass a number of classes of compounds, including isoflavones, lignans, coumestans
, stilbenes, and prenylflavanoids.
The major classes are isoflavones (the most potent), lignans and coumestans
as the main active principles of the liver drugs Eclipta alba and Wedelia calendulacea.
There are three main classes of phytoestrogens: isoflavonoids, coumestans
Isolated constituents from this plant are coumestans
[9,20,53,14], saponins  and ent-kauren diterpenes .
(wedelolactone and demethylwedelolactone) have been mentioned as the possible components behind the protective effect on liver as well as against liver disorders; both compounds exhibited antihepatotoxic activity in assays employing C[Cl.
Coumestrol (Coum), an organic compound in the class of phytochemicals known as coumestans
, has classically been categorized as a phytoestrogen because it binds to the ER (Markaverich et al.
The three major classes of phytoestrogens are the isoflavones, lignans and coumestans
Phytoestrogens are a broad group of nonsteroidal compounds of different structures, falling into three main classes: isoflavones, coumestans
, and lignans.
The three main kinds of phytoestrogens are isoflavones, lignans and coumestans
Phytoestrogens mainly fall into the class of flavonoids: the coumestans
, prenylated flavonoids, and isoflavones are three of the most potent in this class.
