[0016] 1) Extraction of oil from peony stamens: select the peony variety Fengdan, collect unloose powdered peony stamens, and dry at 45°C until constant weight. Crush the dried stamens and pass through a 20-100 mesh sieve for later use. Weigh 3 g of sample, wrap it tightly with filter paper and put it into a Soxhlet extractor, add 150 mL of ether solution, heat in a water bath for 10 hours, and keep the temperature at 45-55 °C. After the extraction is completed, the extract is distilled off under reduced pressure to remove the solvent to obtain the peony stamen oil. Weigh the quality of the oil in the stamens of peony, and the calculation shows that the content of oil in the stamens of peony reaches more than 8%.
[0017] 2) Methylation of peony stamen oil: take 1 mL of peony stamen oil, add 10 mL of methanol and 1 mL of concentrated sulfuric acid solution, stir and heat under reflux for 10 min until the solution is clear and transparent. The components after the methyl este...
