Other types of structures include: nordanshensu, Luo Song phenol, danshensu, threitol, etc. Water-soluble phenolic acids include salvianolic acids A, B and C. Salvianolic acid A is also called danshensu, and its structure is D (+)-β-(3,4-dihydroxyphenyl) lactic acid [D (+)-β-(3,4-dihydroxyphenyl) lactic acid]. Danshensu C is a condensate of 2 molecules of Danshensu; Salvianolic acid) a, b, c, d, e, g; Rosmarinic acid, methyl rosmarinic acid, monomethyl shikimate, dimethyl shikimate, ethyl shikimate, b) shikimate, protocatechuic aldehyde, caffeic acid, isoferulic acid, etc. It also contains baicalin, isopsoralen, ursolic acid, β -sitosterol and carotene [35]. 5-(3- hydroxypropyl) -7- methoxy -2-(3- methoxy -4- hydroxyphenyl) -3- benzo [b] furaldehyde [5(3- hydroxypropyl) -7- methoxy -2-(3- methoxy -4- hydroxyphenyl].
