The preparation of dew grass (2.5kg) was heated with 75% ethanol reflux extraction, ethanol recovery, concentrate. Extraction with ethyl acetate and n-butanol; The ethyl acetate extract was extracted on an Al2O3(neutral) column with gradient elution of chloroform-methanol. The eluted portion of chloroform-methanol (4∶1) was recrystallized by ethyl acetate and methanol to obtain compound 3(200mg). The eluting fraction was prepared by preparative TLC (silica gel GF254, stationary phase; Mobile phase: chloroform-methanol =5∶1) to obtain compound 1(10mg); Tetroxone (5mg) was separated from the eluted part by preparative high performance liquid chromatography (ODChemicalbookS, methanol/water =31∶ 69,242 nm). Bioactive Turkesterone was isolated from Ajugaturkestanica, Turkesterone is a potent ecdysone that is used as an ecdysterone receptor (EcR) agonist in some insect systems.
