[Study on the extraction technology of its flavonoids parts from Tricyrtis maculata growing in Shaanxi Province].

OBJECTIVE

To optimize the extraction technology of total flavonoids from Tricyrtis maculata.

METHODS

With UV spectrophotometry as detection method and the content of total flavonoids as index,using single factor experiment and L9 (3(4)) orthogonal test, the optimal condition was deterined.

RESULTS

The best extraction technology was as follows:soaked the medicinal materials for 15 minutes, water-decoted for 3 times, the solid-water ratio was 1:45, 1:40, 1:40 and the decotion time was 1, 0.5, 0.5 h respectively.

CONCLUSION

The optimal extraction technology is reasonable and provides a basis for its further study.
