Analysis of Chemical Constituents as Flavonoids and Coumarins in Radix Ardisiae from Different Sources / 中国药房

ABSTRACT

OBJECTIVE：To identif y and analyze the flavonoids and coumarins in Radix Ardisiae from different sources. METHODS：UPLC-QE-HF-MS/MS was adopted. The determination was performed on Zorbax Eclipse-C 18 column with mobile phase consisted of acetonitrile- 0.1％ formic acid solution （gradient elution ）at the flow rate of 0.3 mL/min. The column temperature was 30 ℃，and the temperature of injector was 4 ℃. The sample size was 2 µL；ESI source was applied in negative and positive scanning ion mode ，the heater temperature was 325 ℃，the sheath gas pressure was 45 arb，the auxiliary gas pressure was 15 arb，the purge gas pressure was 1 arb，the electrospray voltage was 3.5 kV，the capillary temperature was 330 ℃， S-lens RF level was 55％，scan mode was first-order full sca m/z 100-1 500，data-dependent secondary mass spectrometry scanning （dd-MS2，Top N ＝10），the resolution was 70 000 （first mass spectrometry ） ， 17 500 （secondary mass spectrometry），the collision mode was high-energy collision dissociation. Through retrieving foreign and domestic databases as ChemSpider ，mzCloud，mzVault，PubChem，the structure of the compound was identified on the basis of related literatures and reference data ，and the conten ts were compared. RESULTS & CONCLUSIONS：A total of 47 components were separated from Radix Ardisiae of 3 kinds of sources as Ardisia crenata Sims，A. crispa（Thunb.）A. DC. ，A. crenata Sims var . bicolor （Walk）C. Y. Wu et C. Chen. A total of 17 flavonoids were identified ，including 9 flavonols （quercetin 3-O-rhamnoside-7-O-glucoside， myricetin， rutin， mauritanin， kaempferol， quercetin， isorhamnetin， quercetin，mearnsitrin），3 flavan-3-ols [（-）-epigallocatechin，catechin，epigallocatechin gallate ）2 dihydroflavonoids [fustin ， eriodictyol] and 3 other types [ 3-（2，3-dihydro-benzo[1，4]dioxin-6-yl）-7-hydroxy-2-trifluoromethyl-chromen-4-one，methadone， oriciacridone F] ，10 coumarins {bergenin ，（[ 7-hydroxy-4-methyl-2-oxo-2H-chromen-6-yl）oxy]acetic acid ，[7-（carboxymethoxy）- 4-methyl-2-oxo-2hydroxychromo-3-yl]acetic acid ，4，9-dihydroxy-7H-furo[3，2-g]chromen-7-one，6，7-dihydroxy-4-methylcoumarin， esculetin，fraxetin，7，8-dihydroxy-4-methylcoumarin，4-methylumbelliferyl glucuronide ，scoparone}. Results of content analysis showed that in flavonoids and coumarins ，there were 5 common components in Radix Ardisiae from 3 kinds of sources ，i.e. bergenin（peak 2），[7-（carboxymethoxy）-4-methyl-2-oxo-2-hydroxychromo-3-yl] acetic acid （peak 5），methadone（peak 16）， quercetin（peak 18），oriciacridone F （peak 26）；the contents of common components were significantly different. In addition to 5 common components ，there were 22 different chemical components ，which were compounds corresponding to peaks 1，3，4， 6-15，17，19-25 and 27，respectively. Among them ，compounds corresponding to peaks 3，6，8 and 23 were only found in A. crenata Sims var. bicolor（Walk）C. Y. Wu et C. Chen ；compounds corresponding to peaks 12-15，19 were only found in A. crispa （Thunb.）A. DC. UPLC-QE-HF-MS/MS method can efficiently ，accurately and quickly identify the flavonoids and coumarins in Radix Ardisiae from different sources.
