Abstract:
Objective To study the quality standard of Gardenia jasminoides and its effective parts. Methods TLC was used to identify Gardenia jasminoides and its effective parts. The heavy metals, harmful elements, and moisture in Gardenia jasminoides and its effective parts were examined. The content of Gardenia jasminoides and its effective parts was determined by high performance liquid chromatography. Results TLC method could be used to identify Gardenia jasminoides and its effective parts. The moisture content of Gardenia jasminoides and its effective parts were 8.4% and 3.2%, respectively. ICP-MS was used to determine the contents of five elements in Gardenia jasminoides and its effective parts simultaneously. There was a good linear relationship between arsenic, cadmium, copper, mercury, and lead in the range of 0~20, 0~10, 0~500, 0~5 and 0~20 ng/ml, respectively; The method detection limit of each metal element was 3.3×10−5~1.3×10−3 mg/kg. The relative standard deviation (RSD) of precision was 0.32%~0.82%. RSD values of each element content showed that the method had good repeatability. And the recoveries of arsenic, cadmium, copper, mercury, and lead were 103%~112%, 98%~99%, 98%~99%, 105%~106% and 100%~103%, respectively (n=3). The stability of each element was good within 8 h. The contents of the five elements were within the limits of the current edition of Chinese Pharmacopoeia. The standard curve equation of gardenia was Y=15860X+22543, r=0.9999, indicating that there was a good linear relationship of gardenia in the range of 20.16~322.6 μg/ml. The RSD of precision was 1.86%. RSD of the two samples were 2.38% and 2.60%, respectively, indicated that the method had good repeatability. The average recovery of Gardenia was 99.1% (n=6). The stability of the two solutions was good within 8 h. The contents of gardenia and its effective parts were 5.71% and 34.2%, respectively. Conclusion The research on the quality of Gardenia jasminoides effective parts was carried out based on the research on the quality of Gardenia jasminoides, and the results met the requirements. Therefore, the method established in this experiment could control the quality of Gardenia jasminoides and its effective parts simultaneously.
