Chemicals,commercially available,were purchased from Engergy Chemical,Innochem,Aladdin,or J&K,and used without any further purification.Analytical thin layer chromatography(TLC)was performed on precoated TLC plates(layer 0.20 mm silica gel 60 with fluorescent indicator(UV 254:Merck)).The semi-preparation liquid chromatography(HS-2900P,5μm C18(2)100?),and the eluents were MeOH/H2O(V∶V=3∶7~3∶2).The TLC plates were air-dried and revealed under UV lamp(254/365 nm).1H NMR and 13C NMR spectra were recorded on a Bruker DPX-400 spectrometer.
