[Method] With 5% vanillin-glacial acetic acid-perchloric acid as color developing agent and oleanolic acid as the control substance, the content of diosgenin in D. opposita tubers and bulbils was measured using an ultraviolet visible spectrophotometer at the detection wavelength of 547nm. [Result] The content of diosgenin in D. opposita tubers and bulbils was 0.0164% and 0.0213%, respectively. The average recovery of diosgenin was 98.46% with relative standard deviations (RSD) of 1.36%. Besides, the content of diosgenin in bulbil was slightly higher than that in D. opposita tubers. [Conclusion] The method is simple, easy, accurate, and suitable for content determination of diosgenin in D. opposita tubers and bulbils.

As recorded in ancient literatures, the best A. macrocephala are Shuzhou A. macrocephala and Huizhou A. macrocephala produced in Qianshan of Anhui Province. Their quality is as good as that of Hangzhou A. macrocephala and Yuezhou A. macrocephala in Zhejiang Province, but there are now very few wild resources of Shuzhou and Huizhou A. macrocephala. Although there is a large area cultivation of A. macrocephala in Bozhou of North Anhui, it is not well-known as that produced in Zhejiang. According to the fingerprint study and the chemical components of A. macrocephala, the quality of Huizhou A. macrocephala is as good as that of Zhejiang A. macrocephala, but that of Bozhou A. macrocephala is a little worse. Thus it needs to strengthen the propaganda of Anhui A. macrocephala and the protection of Shuzhou A. macrocephala germplasms, and improve the quality of cultivated A. macrocephala from Bozhou, with the aim to exploit famous Anhui medicines and develop Anhui economy.
