Abstract:Objective To establish a quality standard for rose petals of Hetian, and provide experimental basis for the quality control of the medicinal materials. Methods According to the general principles of Chinese pharmacopoeia in 2015 the total ash content, acid insoluble ash and extract were determined. TLC method was used to identify the crude drug with quercetin as the reference. The content of quercetin in rose petals was determined by RT-HPLC with methanol-0.1% phosphoric acid (56∶44) as the mobile phase. Results The method of TLC had specificity, the total ash was 4.9% in average, the acid insoluble ash was 0.19% in average, and the extract was 45.8% in average. The average content of quercetin was 0.21%. Conclusion According to the experimental results, a quality standard for rose petals is established preliminarily, and the quality standard of the medicinal plants can be used for the quality control of rose petals of Hetian.
