ABSTRACT
AIM To study the chemical constituents from the fruits of Evodia rutaecarpa (Juss.) Benth.and their biological activities.METHODS The ethyl acetate fraction of 80％ ethanol extract from E.rutaecarpa was isolated and purified by silica column and recrystallization,then the structures of obtained compounds were identified by physicochemical properties and spectral data.The antitumor and antifungal activities were determined by MTT and mycelium growth method,respectively.RESULTS Ten compounds were isolated and identified as rutaecarpine (1),evodiamine (2),1-methyl-2-undecyl-4 (1H)-quinolone (3),1-methyl-2-tridecyl-4 (1H)-quinolone (4),wuchuyuamide Ⅰ (5),wuchuyuamide Ⅲ (6),wuchuyuamide Ⅳ (7),β-sitosterol (8),β-daucosterol (9),dehydroevodiamine (10).Compounds 1,2,10 had certain inhibitory effects on MDA-MB-231,LoVo,A2780 and HeLa with the IC50values of 0.65-29.45 μmol/L.Compound 1 had a certain inhibitory effect on Botrytis cinerea,Glomerella cingulata and Rhizoctonia solani with the inhibitory rates of 18.12％-49.57％.CONCLUSION Compounds 3-7 are isolated from this plant for the first time,compounds 1,2,10 have strong biological activities.
ABSTRACT
<p><b>OBJECTIVE</b>To investigate the cholesterol 7alpha-hydroxylase gene -204A/C polymorphism and its relationship with serum lipids and apolipoproteins (apo) levels in patients with endogenous hypertriglyceridemia (HTG) in Chinese population in Chengdu area.</p><p><b>METHODS</b>The genotype and allele frequencies of cholesterol 7alpha-hydroxylase gene -204A/C polymorphism were analyzed by polymerase chain reaction and restriction fragment length polymorphism (PCR-RFLP). Serum lipids were measured by enzymatic kits and apolipoproteins AI, AII, B100, CII, CIII and E were measured by the RID kits in 132 HTG patients and 212 control subjects.</p><p><b>RESULTS</b>Allele frequencies of A and C were 0.602 and 0.398 in HTG group and 0.601 and 0.399 in control group, respectively. There was no significant difference of allele and genotypes frequencies between HTG and control groups (P> 0.05). In HTG group, carriers with the genotypes CC and AC were associated with significantly higher concentrations of triglycerides and apoCIII compared with those with genotype AA (P< 0.05). In the control group, carriers with the genotypes CC and AC were associated with significantly lower serum high density lipoprotein cholesterol (HDL-C) level compared with those with genotype AA (P< 0.05). In the male control group, carriers with the genotypes CC and AC had elevated levels of serum triglycerides than those with genotype AA (P< 0.05).</p><p><b>CONCLUSION</b>These results suggest that -204A/C polymorphism in the CYP7A1 gene does not relate with HTG but may has an effect on serum triglyceride and apoCIII levels in patients with endogenous HTG, the serum HDL-C level in control subjects and the serum TG level in male control subjects.</p>
