ABSTRACT
Objective: To establish the fingerprint of Lonicera japonica superfine powder with different polarity and study its correlation of antibacterial activity. Methods: Six different polarity extracts were obtained using the solvent system extraction and then were detected by HPLC with gradient elution. Pharmacological activities were detected by antibiotic indexes in vitro. The correlation between the pharmacological indexes and the information of HPLC fingerprint was discovered by multiple linear regression analysis and compound groups related to pharmacological indexes were obtained. Results: Antibacterial effect fingerprint of L. japonica can be established by HPLC fingerprint of ethyl acetate fraction. Conclusion: The method developed is practical and can be used for evaluating the quality control of L. japonica powder.
ABSTRACT
OBJECTIVE: To study the effect of various polarity fractions extracted from Sancaofang (SCF) and its combination on proliferation of human lung adenocarciaoma SPC-A-1 cells for bolting the most effective position of anti-tumor and suitable compatibility regimes.METHODS: Ethanol extraction and water extraction were adopted to prepare 95%,60% and 30% ethanol extract portion,water extract portion of SCF and compound decoction.The MTT assay was used to determine the effect of various polarity fractions of SCF,decoction and its combination on SPC-A-1 cells proliferation.RESULTS: IC50 of 60% ethanol extract was the smallest for SPC-A-1 cells.60% ethanol extract combined with 95% ethanol extract acts as a stimulus to anti-tumor activity significantly.CONCLUSION: The best suitable compatibility regimes were 95% ethanol extract combined with 60% ethanol extract.The liposolubility extract of SCF can be applied for anti-tumor.
