The HPLC-MS / MS method is used for establishing the blood plasma quantitative analysis method of related components in 46 antiviral traditional Chinese medicine compositions, including alkaloid components in ephedra herb, lignan, phenethyl alcohol, flavonoid glycoside components in forsythia suspense herb, triterpenoid saponin components in licorice herb, flavone, organic acid components in honeysuckle flower herb, anthraquinone components in rhubarb herb, cyanogenic glycoside components in fried bitter apricot kernel herb and the like. The detection method is verified in terms of selectivity, accuracy, precision and stability, and the method is simple and accurate, and meets the requirements of ICH M10 for biological analysis method. By the detection method, the pharmacokinetics of the blood entering original components in the antiviral traditional Chinese medicine composition in the body can be conveniently researched, and the pharmacokinetic markers of the antiviral traditional Chinese medicine composition can be screened according to the absorption of the compounds in the body, and the method has high practical value.

[0293] Drug determination concentration in rat plasma

[0294] The pretreatment method of enzyme hydrolysis followed by methanol protein precipitation was combined with the established HPLC-MS / MS method to quantitatively analyze the 46 main components in the plasma of rats after intragastrical administration. According to the blood drug concentration calculated by the calibration curve, the DAS2.0 software was introduced, and the non-compartment model was used to fit the pharmacokinetic parameters (AUC 0-t , T max , C max , t 1 / 2z , V z / F and CL z / F ) of the 46 compounds, and the specific results are shown in Table 7.

[0295] Table 7 Pharmacokinetic parameters of 46 compounds to be detected in rats (n=6)

[0296]

[0297]

[0298]

[0299] The average plasma concentration-time curve of the 46 compounds is shown in Figure 1. Figures 47-62From the average plasma concentration-time curves and pharmacokinetic analysis results, it can be seen that the plasma concentrations and metabolic characteristics of each group are quite different. Organic acids, anthraquinones, caffeic acid, phenylethanoid glycosides and alkaloids (except pseudoephedrine) compounds have the characteristics of fast absorption, short peak time and slow elimination, while rhodioside, flavonoids and triterpenoids have the characteristics of slow absorption and long peak time. AUC 0-t The top 10 compounds in terms of AUC values are: rhodioside (mainly derived from the medicinal material Rhodiolae Radix), caffeic acid (mainly derived from the medicinal material Lonicerae Japonicae Flos), rhein (mainly derived from the medicinal material Radix et Rhizoma Rhei), glycyrrhetinic acid (mainly derived from the medicinal material Radix Glycyrrhizae), kaempferol (mainly derived from the medicinal materials Rhodiolae Radix and Radix et Rhizoma Rhei), quinic acid (mainly derived from the medicinal material Lonicerae Japonicae Flos), wild black cherry glycoside (mainly derived from the medicinal material Semen Armeniacae Amarum), forsythia ester glycoside E (mainly derived from the medicinal material Forsythiae Fructus), gallic acid (mainly derived from the medicinal materials Rhodiolae Radix and Radix et Rhizoma Rhei), and ferulic acid (mainly derived from the medicinal materials Radix et Rhizoma Bupleuri and Herba Gentianae Macrophyllae). Among them, rhodioside and rhein are the quality control components of Rhodiolae Radix and Radix et Rhizoma Rhei, respectively, with AUC 0-t values of 132211.18±121869.67 μg / L*h and 32865.26±12913.65 μg / L*h in rat plasma, respectively, which are the main prototype components exposed in rat plasma after oral administration of Lianhua Qingwen Capsules, and can be used as potential pharmacokinetic markers of Lianhua Qingwen Capsules. Among them, glycosides include flavonoid glycosides such as formononetin, isoquercitrin, chrysosplenium glycoside, hyperoside, kaempferol-3-O-rutinoside and other compounds, which have low content in vivo. The possible reasons are: 1) the compounds undergo hydrolysis reaction in vivo to remove the glycoside bond, and exist in the form of metabolites; for example, chrysosplenium glycoside is rapidly absorbed (T max 0.11±0.07h; t 1 / 2 2.65±1.63h) in vivo and metabolized into chrysosplenium, which is the main form of chrysosplenium glycoside in rats; 2) β-glucuronidase is added in the pretreatment of plasma samples to hydrolyze the β-D-glucose bond combined to the non-reducing end, releasing β-D-glucose and the corresponding prototype ligand, which also hydrolyzes part of the glycoside prototype components, resulting in low content in vivo.

[0300] The plasma concentrations of compounds with small molecular weights such as caffeic acid, kaempferol, quinic acid, gallic acid, ferulic acid, and p-coumaric acid are high, and the main reasons are speculated to be the original content of the medicinal materials and the conversion from other components. For example, 3,5-dicaffeoylquinic acid, 4,5-dicaffeoylquinic acid, cryptogreen acid, chlorogenic acid, and neochlorogenic acid are all condensed phenolic acids generated from caffeic acid and quinic acid.

[0301] Pseudoephedrine, forsythoside B and kaempferol-3-O-rhamnoside have elimination half-lives less than 2 h, and rutin, glycyrrhizin, luteolin, isoliquiritigenin and glycyrrhetic acid have elimination half-lives greater than 25 h. The plasma concentration-time curves of multiple compounds exhibit double peaks. For example, glycyrrhizin appears at 0.08 h-1 h and 6 h-12 h after taking Lianhuaqingwen, respectively Figure 58 ), and prunusin appears at 0.5 h-1 h and 6 h-12 h after administration, respectively Figure 50 ), wherein the first peak is produced by the absorption of the prototype components in Lianhuaqingwen through the intestinal tract. The second peak of glycyrrhizin is produced by the de-glycosylation of glycyrrhizin in the body after the absorption of glycyrrhizin / glycyrrhizin apioside in the intestinal tract through microbial metabolism. The second peak of prunusin is mainly produced by the de-glycosylation of amygdalin.

[0302] In addition, by comparing the plasma concentrations and the detection of compounds in medicinal materials, it is found that the concentrations of prunusin and glycyrrhetic acid in medicinal materials are low, and the plasma concentrations gradually increase during the absorption and distribution in the body. In our previous studies, it is known that prunusin and glycyrrhetic acid are the main metabolites of amygdalin and glycyrrhizic acid in the body, respectively, and play a major pharmacodynamic effect. In the pharmacokinetic study this time, as the plasma concentrations of amygdalin and glycyrrhizic acid gradually decrease, the contents of prunusin and glycyrrhetic acid in the plasma gradually increase, and reach the peak of drug concentration at 6.17±4.40 h and 14.17±8.16 h, respectively. This data again confirms this conclusion.

[0303] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement or improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
