Embodiment 1
[0026] Example 1 Preparation of Zijinsha Extract 1
[0027] After taking 500g of Zijinsha medical material and pulverizing it, heat and reflux extraction with 80% ethanol for 2 times, each extraction for 2 hours, the amount of solvent used is 4000ml, the combined extracts are concentrated to dryness under reduced pressure to obtain 96g of ethanol extract. A proper amount of the ethanol extract is weighed, and the total content of the total coumarins and chromones measured by UV-Vis spectrophotometry is 29.4%. Determination of Hydrated Oxidized Precurolactone, Eperprenol, 3'(R)-+-Hyculol, 3'-O-Acetyl Halgol, and Isoimperatorin by High Performance Liquid Chromatography They are 8.24%, 0.68%, 0.41%, 0.43%, and 1.89%, respectively.
Embodiment 2
[0028] Example 2 Preparation of Zijinsha Extract 2
[0029] After crushing 50 g of Zijinsha medicinal material, ultrasonically extract with methanol for 0.5 hours each time, the amount of solvent used is 400 ml, the combined extracts are concentrated to dryness under reduced pressure to obtain 4.2 g of methanol extract. A proper amount of methanol extract was weighed, and the sum of the contents of coumarins and chromones was measured by ultraviolet-visible spectrophotometry to be 26.3%. Determination of Hydrated Oxidized Precurolactone, Eperprenol, 3'(R)-+-Hyculol, 3'-O-Acetyl Halgol, and Isoimperatorin by High Performance Liquid Chromatography They are 7.37%, 0.63%, 0.31%, 0.33%, and 1.61%, respectively.
Embodiment 3
[0030] Example 3 Preparation of Zijinsha Extract 3
[0031] After taking 100g of Zijinsha medicinal material and pulverizing it, extract by cold soaking in acetone twice for 24 hours each time, the amount of solvent used is 1000ml, the combined extracts are concentrated to dryness under reduced pressure to obtain 9.2g of acetone extract. An appropriate amount of acetone extract was weighed, and the sum of the contents of coumarins and chromones was measured by ultraviolet-visible spectrophotometry to be 33.5%. Determination of Hydrated Oxidized Precurolactone, Eperprenol, 3'(R)-+-Hyculol, 3'-O-Acetyl Halgol, and Isoimperatorin by High Performance Liquid Chromatography They were 9.73%, 1.04%, 0.86%, 0.88%, and 2.31%, respectively.
