overview | the four flavors of calamus are composed of four kinds of traditional Chinese medicines, including galangal, purple sand, wood fragrance and calamus, which are commonly used in Mongolian medicine. The chemical components of Galangal in the four flavors of Acorus calamus are mainly flavonoids, diphenylheptane, volatile oils, glycosides and phenylpropanoids, etc., in addition, it also contains a variety of trace elements. Flavonoids include galangin, Galangin -3-methyl ether, kaempferol -4-methyl ether, kaempferol, quercetin, josonin, dihydrogalangin, catechin, etc, dihydroheptane compounds mainly include diphenylheptane A, diphenylheptane B, diphenylheptane C, diphenylheptane D, phenyl-4-ene-3heptanone, etc. Among them, the content of flavonoids such as galangin and kaempferol is higher. The rhizome of Acorus calamus mainly contains volatile oil, amino acids, phenylpropanoids and sugars. The root of Radix wood contains 0.3%-3% volatile oil, 0.05% of Radix wood, inulin 18%, among them, the main components in the volatile oil are wood lactone, dihydrowood lactone, α-wood alcohol, α-wood acid, Saussurea lactone, dehydrowood lactone, isodehydrowood lactone, Weirui Kunsen, iso-earth hydrogen wood lactone, mono-taxane, α and β wood alkene and α and β-ionone, among which the content of wood alkane lactone and dehydrowood lactone is higher. From the above, it can be seen that the four flavors of Acorus mainly contain flavonoids, phenylpropanoids, anthraquinones, alkaloids, terpenoids and other components. |
