Objective: To study the chemical constituents from the aerial parts of Mesona chinensis
in order to explore the possibility of the homology between medicine and food.Method: The aerial parts of dry M. chinensis were extracted with 95% ethanol
then the solvent was decompressed and extracted with hexane and ethyl acetate respectively to get hexane fractions and ethyl acetate fractions. The ethyl acetate fractions were isolated and purified by column chromatography with silica gel
MCI and Sephadex LH-20
and their structures were identified by NMR and MS
physicochemical properties and reference literatures.Result: Thirteen compounds were isolated and identified as ursolic acid (1)
oleanic acid (2)
2α
3α-dihydroxyolean-12-en-28-oic acid (3)
corosolic acid (4)
2α
3α
19α-trihydroxyurs-12-en-28-oic acid (5)
stigmasterol (6)
β-sitosterol (7)
kaempferol (8)
quercetin (9)
3-indoleformic (10)
aurantiamide acetate (11)
heptadecanoic acid (12)
palmitic acid (13).Conclusion: Compounds 3-5
7
10-13 were isolated from the plants of M. chinensis and Mesona for the first time.
