Abstract:
Taking Salvia miltiorrhiza flowers as the test materials,the powder colors (L*,a*,and b* values) of different Salvia miltiorrhiza flowers (white,blue,purplish red,and purple) were determined by the colorimeter;HPLC was used to determine the content,and DPPH·scavenging method,FRAP method,tyrosinase activity assay,and oxford cup method were used to determine the in vitro antioxidant,melanin synthesis inhibition,and antibacterial activity of the phenolic ketones in Salvia miltiorrhiza flowers.The correlation analysis of the relationship among color,composition and activity of Salvia miltiorrhiza flowers was carried out by SPSS 17.0 software.The contents and biological activities of phenolic ketones in Salvia miltiorrhiza flowers were determined,in order to provide references for their rational utilization and development.The results showed that total anthocyanins,total phenolic acids and total flavonoids in purple Salvia miltiorrhiza flower were the highest.The DPPH·clearance rate,Fe3+ reducing ability and tyrosinase activity inhibition ability of different color Salvia miltiorrhiza flowers were purple > purplish red > blue > white.The purple Salvia miltiorrhiza flowers had the strongest antibacterial ability,and the inhibitory effect on escherichia coli was comparable to roxithromycin.Correlation analysis showed that color value a* and b* of Salvia miltiorrhiza flowers was positively correlated with total phenolic acid,total anthocyanin content,antioxidant capacity and tyrosinase activity inhibition rate.Color value b* was negatively correlated with salvianolic acid B content,c* was positively correlated with the contents of total anthocyanin,total phenolic acid and rosmarinic acid,and the inhibition rate of tyrosinase activity.In summary,the darker the purple degree of Salvia miltiorrhiza flower,the stronger the total phenolic acid,total anthocyanin,antioxidant activity,antibacterial ability and inhibition of melanin deposition.
