Coumestan
Coumestan is a heterocyclic organic compound. Coumestan forms the central core of a variety of natural compounds known collectively as coumestans. Coumestans are oxidation products of pterocarpan that are similar to coumarin. Coumestans, including coumestrol, a phytoestrogen, are found in a variety of plants. Food sources high in coumestans include split peas, pinto beans, lima beans, and especially alfalfa and clover sprouts. Coumestrol has about the same binding affinity for the ER-β estrogen receptor as 17β-estradiol, but much less affinity than 17α-estradiol, although the estrogenic potency of coumestrol at both receptors is much less than that of 17β-estradiol. Because of the estrogenic activity of some coumestans, a variety of syntheses have been developed that allow the preparation of coumestans so that their pharmacological effects can be explored.

Eclipta Alba
''Eclipta prostrata'', commonly known as false daisy, ''yerba de tago'', ''Gunta kalagaraku/Gunta galagaraku'', ''Karisalankanni'', and ''bhringraj'', is a species of plant in the family Asteraceae. It is widespread across much of the world. This plant has cylindrical, grayish roots. Solid, circular, purplish stems with white fine hairs 0.8m. Leaves arranged in opposite pairs, hairy in two-sided, lanceolate, serrated 2–12.5 cm long, 5-35 mm wide. The solitary flower heads are in diameter, with white florets. The bumpy achenes are compressed and narrowly winged. Steenis, CGGJ van (1981). ''Flora, untuk sekolah di Indonesia''.

Catechols
Catechol ( or ), also known as pyrocatechol or 1,2-dihydroxybenzene, is a toxic organic compound with the molecular formula . It is the ''ortho'' isomer of the three isomeric benzenediols. This colorless compound occurs naturally in trace amounts. It was first discovered by destructive distillation of the plant extract catechin. About 20,000 tonnes of catechol are now synthetically produced annually as a commodity organic chemical, mainly as a precursor to pesticides, flavors, and fragrances. Catechol occurs as feathery white crystals that are very rapidly soluble in water. Isolation and synthesis Catechol was first isolated in 1839 by Edgar Hugo Emil Reinsch (1809–1884) by distilling it from the solid tannic preparation catechin, which is the residuum of catechu, the boiled or concentrated juice of ''Mimosa catechu'' (''Acacia catechu''). Upon heating catechin above its decomposition point, a substance that Reinsch first named ''Brenz-Katechusäure'' (burned catechu acid) ...
