[Study on Quality Evaluation of Ophiopogonis Radix in Sichuan].

[Article in Chinese]

Abstract

Objective:

To evaluate the quality of Ophiopogonis Radix from produce area, circulation link and clinical application in Sichuan, and to provide the theoretical basis for the quality control of Ophiopogonis Radix in Sichuan.

Methods:

105 samples were collected from different produce area, market, factory of decoction pieces, drugstore in Sichuan. The content of moisture,total ash, extractum, total saponin, heavy metal, harmful element, pesticide residues, sulfur dioxide were measured by the methods which recorded in Chinese pharmacopoeia. The content of ophiopogonin D, methylophiopogonanone A, methylophiopogonanone B were measured by HPLC.

Results:

The content of moisture, total ash, extractum, total saponin in 105 samples Ophiopogonis Radix in Sichuan were at 5. 7%~ 17. 9%,0. 9% ~ 3. 4%,68. 7% ~ 95. 1%,0. 12% ~ 0. 57%,respectively. Over standard rate of sulfur dioxide was 23. 81%. The content of heavy metal and harmful element was conform to the limitation requirement of Chinese pharmacopoeia. Three kinds of organic pesticide had not been checked out. The content of ophiopogonin D, methylophiopogonanone A,methylophiopogonanone B were at 0. 04~ 0. 30 mg/kg,0. 0170 ~ 0. 0837 mg/kg,0. 0049 ~ 0. 0370 mg/kg, respectively.

Conclusion:

The quality of 105 samples are up to the requirement with the provisions of the Chinese pharmacopoeia. Actually,the mandatory standard was not perfect, especially lack of standard in security. It is suggested that strengthening supervision of sulfur dioxide and paclobutrazol residual according to the actual situation for ensuring the safe and effective of Ophiopogonis Radix in clinical application.
