ABSTRACT
Objective To compare the efficacy difference of Green Forsythiae Fructus and Ripe Forsythiae Fructusby using Lianqiao powder and Yinqiao powder in the classic formula; To provide experimental evidence for the guidance of one for dual-use of the Forsythiae Fructus. Methods The guinea pig sore model was made with Staphylococcus aureus. 40 guinea pigs were randomly divided into blank group, model group, Lianqiao powder Green Forsythiae Fructus group and Lianqiao powder Ripe Forsythiae Fructus group. The blank group and the model group were fed with normal saline, while Lianqiao powder Green Forsythiae Fructus group and Lianqiao powder Ripe Forsythiae Fructus group were treated with 1.2 g raw medicine/kg liquid Lianqiao powder Green Forsythiae Fructus and Lianqiao powder Ripe Forsythiae Fructus for 7 d. The symptom score, blood and pathological changes of guinea pig soreness were observed. The model of acute lung injury was induced by 10% LPS aerosol inhalation. 40 rats were randomly divided into blank group, model group, Yinqiao powder Green Forsythiae Fructus group and Yinqiao powder Ripe Forsythiae Fructus group. The blank group and the model group were fed with normal saline, while Yinqiao powder Green Forsythiae Fructus group and Yinqiao powder Ripe Forsythiae Fructus group were treated with 4 g raw medicine/kg liquid Yinqiao powder Green Forsythiae Fructus and Yinqiao powder Ripe Forsythiae Fructus for 10 d. The levels of IL-6, TNF-α and IL-1β in the lung lavage fluid were detected. Results The effect of Lianqiao powder Green Forsythiae Fructus on the wound healing of guinea pig sore wound was faster than that of Lianqiao powder Ripe Forsythiae Fructus, but there was no significant difference between Lianqiao powder Green Forsythiae Fructus group and Lianqiao powder Ripe Forsythiae Fructus group in inhibiting the secretion and pathological changes of guinea pig sore wound. The levels of IL-6, TNF-α and IL-1β in Yinqiao powder Green Forsythiae Fructus group was lower than that in Yinqiao powder Green Forsythiae Fructus group, without statistical significance. Conclusion It is verified that there is efficacy differences between Green Forsythiae Fructus and Ripe Forsythiae Fructus in the different Chinese herbal compound.
ABSTRACT
OBJECTIVE:To study and compare the volatile constituents in Forsythia suspensa and old F. suspensa. METH-ODS:Steam distillation method was adopted to extract volatile oil. GC-MS was adopted to determine the content of volatile oil:the chromatographic conditions:the column was HP-5MS,inlet temperature was 200 ℃,the carrier gas was nitrogen,split ratio was 20 to 1,by programmed temperature,flow rate was 1 ml/min,the injection volume was 1 μl;MS conditions:ion source was electric bombardment ionization source,electron energy was 70 eV,the interface temperature was 280 ℃,ion source temperature was 230 ℃,quadrupole temperature was 150 ℃,electron multiplier voltage was 2 300 V,and mass scanning range was 29-350 amu. RESULTS:The extraction yield order of volatile oil was that F. suspensa heart was higher than F. suspensa,followed by F. suspensa shell and old F. suspensa;there were 18 common peaks in the volatile oil,and the content of β-pinene was the maxi-mum,followed by α-pinene,β-phellandrene,terpinen-4-ol and terpinene;in addition,4-methylene-1-cyclohexanone,3-cyclohex-ene-1-methanol,cumene formaldehyde,1,7-trimethyl-4-methylenedecahydro,palmitic acid,nutmeg aldehyde can only be detected in the volatile oil of old F. suspensa;while α-phellandrene,ocimene,α-terpineol,α-pinocarvone,cis-piperitol,bornyl acetate,α-cubebene and germacrene D can only present in F. suspensa. CONCLUSIONS:The main chemical components in the volatile oil of F. suspensa and old F. suspensa are basically the same,but there are also some differences. The discovery can provide some ba-sis for the material basic research in the pharmacodynamic differences of F. suspensa.
