OBJECTIVE To study the protective effect of petroleum ether fraction(AERP) and water soluble fraction(AERW) of Arnebia euchroma(Royle) Johnst. on acute liver injury in mice, and to isolate the effective components of petroleum ether fraction with better effect, and to study the antihepatitis B virus effect of its effective components. OBJECTIVE Forty eight C57 mice were randomly divided into 6 groups. After 14 days of administration, lipopolysaccharide/D-galactosamine(LPS/D-Galn) was used to induce acute liver injury with inflammatory infiltration at the last 2 hours. The liver and spleen index, the content of AST and ALT in mouse serum and the content of NO in liver homogenate were measured, and the pathological section of liver tissue was investigated. The petroleum ether extract was separated by normal silica gel, reverse silica gel and thin layer preparation plate, and four active naphthoquinones were obtained. The antihepatitis B virus activity of the four active naphthoquinones on HepG2.2.15 cells was detected by MTT method. RESULTS Both AERW high-dose group and AERP low-dose group can reduce the activity of AST and ALT in serum and the content of NO in liver tissue of mice to varying degrees, and improve the pathological changes of liver tissue to varying degrees. After comparative analysis, AERP has better liver protective and anti-inflammatory effects. The extraction method of AERP was optimized to obtain AERP with more effective components, and four active naphthoquinones were isolated: isovalerylshikonin, acetylshikonin, 2,3-dimethylpentenylshikonin and shikonin. Four active naphthoquinones have good inhibitory effects on HepG2.2.15 cells. CONCLUSION The results show that AERW and AERP have a good protective effect on acute liver injury. The liver protective effect of AERP is better than that of AERW. The four active components of AERP have a good inhibitory effect on HBV. AER extract has a significant liver protective effect, and the active components of AER have a significant inhibitory effect on hepatitis B virus.
