ABSTRACT
OBJECTIVE: To prepare standard decoction of fried Perilla frutescens seed and study the quality standard. METHODS: According to the preparation requirements of standard decoction, 17 batches of standard decoction of fried P. frutescens seed were prepared, and the yield of paste was calculated. HPLC method was used for quantitative analysis of rosmarinic acid in standard decoction of fried P. frutescens seed. The determination was performed on Agilent 5 TC-C18(2) column with mobile phase consisted of methanol-0.1% formic acid solution (40 ∶ 60, V/V) at the flow rate of 1.0 mL/min. The detection wavelength was set at 330 nm, and column temperature was 30 ℃. The sample size was 5 μL. The transfer rate was calculated. HPLC fingerprint was established for 17 batches of standard decoction of fried P. frutescens seed, and analyzed by using TCM Chromatogram Fingerprint Similarity Evaluation System (2012 edition). The chromatogram peaks were identified by comparing retention time of common peak. RESULTS: The yield of paste were 5.55%-9.75% in 17 batches of standard decoction of fried P. frutescens seed. The contents of rosmarinic acid were 0.44%-1.58%, and average content was 1.08%. The transfer rates of rosmarinic acid were 18.31%-34.32%, and average transfer rate was 25.42%. In HPLC fingerprints for 17 batches of standard decoction of P. frutescens seed, a total of 11 common peaks were identified, and the similarity was higher than 0.95. Five common peaks were identified, namely caffeic acid (peak 3),luteolin (peak 5), rosmarinic acid (peak 8) , luteolin (peak 9), apigenin (peak 10). CONCLUSIONS: The quality control method of standard decoction of fried P. frutescens seed is established, which can provide reference for the formulation of the quality standard of fried P. frutescens seed granules and related preparations.
