AIM: To establish the quality standard of Guijiu(Rhizome or root of Podophyllum emodi(Wall.) Ying,Dysosma versipellis(Hance) M.Cheng or Dysosma pleiantha(Hance) Woodson.which herbs contained lignans including podophyllotoxin. METHODS: The microscopic examination, physio-chemical method such as LC-MS had been used. RESULTS: These methods can be used for the identification and quantitative analysis of Guijiu. CONCLUSION: The method proposes microscopic examination technique and physio-chemical method such as LC-MS fingerprint and LC-MS-MS for the identification and quantitative analysis of the herbs.

AIM: Euphorbia is the unprocessed root of Euphorbia ebracteolata Hayata or Euphorbia Fischeriana Steud,or Stellera chamaejasme L.To establish the quality standard for these potent herbs. METHODS: The microscope examination techniques,physio-chemical methods such as HPLC/UV and LC-MS-MS had been used. RESULTS: The content of ebracteolata compund B in E.Fischeriana was 0.01%,and in E.ebracteolata was(0.01%)-0.02%.But the skimmetine,chamaechromone and neochamaejasmin A had not been chekout in both species.The content of skimmetine,chamaechromone and neochamaejasmin A was 0.57%-2.12 %,0.86%-(1.6%),and 0.45%-0.96% in S.chamaejasme.But the ebracteolata compund B had not been chekout in this specie. CONCLUSION: The method can be applied to conventional testing of Euphorbia.

AIM: Radix Aconite is unprocessed parent root tuber of Aconitum carmichaeli Debx.containing toxic diterpenoid alkaloids such as mesaconitine,aconitine and hypaconitine.To establish the quality standard for this potent herb. METHODS: The microscopic examination technique,HPLC-UV and LC-MS-MS methods had been used. RESULTS: These methods can be used to analyse the quality of this potent herb. CONCLUSION: This paper proposes microscopic examination technique and physio-chemical methods such as HPLC-UV and LC-MS-MS for the identification and quantitative analysis of the herbs.
