[Preliminary studies on chemical constituents and pharmacological action of Eclipta prostrata L].

OBJECTIVE

To study the pharmacologically active components of Eclipta prostrata.

METHOD: The components were extracted by alcohol and isolated by silica gel column and subjected to pharmacological screening.

RESULT: Four compounds were isolated from E. prostrata, of which two were identified as stigmasterol and alpha-terthienyl.

CONCLUSION

alpha-Terthienyl was isolated from the plant for the first time. The EtOAc part of alcoholic extraction exhibits significant hepatoprotective activity against carbon terachloride-induced liver injury in rats.
