목적；건립산창자총삼첩산함량적측정방법。방법：이웅과산표준품위대조，5％향초철．빙작산화고록산위현색제，자외분광광도법측정산창자지화협중총삼첩산적함량。결과：산창자지화협중총삼첩산함량분별위0．082％，0．689％，가양회수솔분별위100．61％，102．60％；RSD분별위2．16％，1．41％。결론：차방법간단역조작，차결과준학，가고。
Objective： To establish the determination methods of the total Triterpenoid contents from Litsea cubeba. Methods： Took Ursolic acid as standard, contents of total Triterpenoid in Litsea cubeba stems and leaves were determined by spectrophotometer with 5 % vanillin-acetic acid and perchloric acid as colored reagent. Results： The average value of contents of total Triterpenoid in Litsea cubeba stems and leaves were 0,082 % and 0.689 %, and the average recovery of the method were 100.61% and 102.60 %. The RSD of reproducibility test were 2.16 % and 1.41% respectively. Conclusion： The method is simple and easy to operate, the result is accurate and reliable.
