This study aims to compare the internal chemical composition and appearance indifferent growth patterns and years of Saposhnikovia divaricata decoction pieces,which was applied to explore the effect of growth patterns and years on its quality. The appearance characteristic data of 55 batches of different growth patterns and years of S. divaricata were collected using PANTONE color card.High performance liquid chromatography( HPLC) was used to determine the contents of prim-O-glucosyl-cinmifugin,cimifugin,4-O-β-D-glucosyl-5-O-methylvisamminol and sec-O-glucosylhamaudol. The content of alcohol soluble extract and water-soluble extract were determined by hot-dip method. The content of volatile oil was determined by steam distillation. The correlation between growth patterns and years and the contents of 4 chromones,extracts and volatile oil were analyzed by modern statistical methods. Also,the method of comprehensively evaluating the quality of Chinese herbal pieces was developed by combining the growth patterns and years,appearance and chemical indexes. MTT assay was used to evaluate the effects on the survival rate of RAW264. 7 cells at four different concentrations of chromones and LPS was used to stimulate well-growing RAW264. 7 cells to establish an inflammatory model. The contents of NO and TNF-α in cell supernatant were detected by NO test kit and ELISA method. The contents of alcohol soluble extracts and water-soluble extracts in different growth patterns and years are: wild productsperennial cultivationannual cultivation; the contents of volatile oil are: wild productsperennial cultivationannual cultivation; the contents of four chromones are: wild productsperennial cultivation and annual cultivation. There was no significant difference between the sum of the two indexes in the Pharmacopoeia of perennial cultivation and wild products. 4 chromones showed no toxicity to RAW264. 7 cells at 5 mg·L-1. The release of NO and TNF-α was inhibited by 4 chromones and the anti-inflammatory effect of cimifugin was the best. In summary,there are obvious differences in appearance characteristics,internal quality and effects between different growth patterns and years. It showed that the wild products were superior to the perennial cultivation and the perennial cultivation was superior to the annual cultivation. In order to alleviate the shortage of wild S. divaricata resources,it is suggested that the Chinese Pharmacopoeia standard should increase the character of decoction pieces of perennial cultivation,and properly raise the limit requirement of the sum of the two indexes in the Chinese Pharmacopoeia to ensure the clinical demands and effect. |
