The materials such as the onion oil that some solvent methods are produced, the pigment in solvent are easily remained, it is impossible to for human body long-term taking, main shadow
There is harmful effect to human body when ringing curative effect and long-term taking.It is pure with the onion oil of ad hoc approach of the present invention extraction without bad smell
Degree reaches 99. 85%, the loss without thermal sensitivity volatile component and destruction, and high income, and yield reaches 3.96-4.9%；Use
The purity of resveratrol micro mist is 99.5%；Punica granatum L. polyphenol is extracted as known method, it is desirable to the pomegranate of commercially available purity more than 85%
Polyphenol；Maize germ oil is extracted using ad hoc approach of the present invention, and with corn peel cracking agent is done, and is had to maize germ
Phasic property is good, does not produce pollution, and the characteristics of cell-wall breaking ratio is high, the purity of maize germ oil is 99.94%.The combination of the present invention
Onion oil in thing can reduce triglyceride and cholesterol in serum, and its amount for reducing triglyceride reaches nature slippage
More than 2 times, the amount for reducing cholesterol reaches more than 1.5 times of nature slippage, and research shows, onion oil is individually used for dropping blood
Fat, its effect has substantially reduction, but sulfur compound, flavonoids etc. more than 60 in onion oil than chemicalses such as Etofylline Clofibrate and clofibrates
Beneficial is planted, while with effect for reducing blood fat, is acted on stronger anti-oxidant and anti-platelet aggregation etc., further
Research shows, the content height of blood fat reflects the level of internal lipid metabolism, and work as artery and venous capillary elasticity compared with
When low, the level of relative of metabolism lipid is reduced, and when particularly lacking linoleic acid in vivo, cholesterol will be with saturated fatty acid group
Close, dysbolism occurs, precipitate on vascular wall, affect when platelet aggregation, antioxidant content are relatively low in blood
Lipids contents.The present invention is aided with maize germ oil, resveratrol micro mist and Punica granatum L. polyphenol, to improve blood vessel elasticity, reduces blood
Saturated fatty acid is combined with cholesterol in pipe, and contained antioxidant can capture and neutralize free radical, anti-platelet aggregation.It is dynamic
Thing experiment shows：The present composition has significantly synergy, the effect with obvious reducing blood lipid.The present composition is also
Endovascular harmful substance can be eliminated.The present composition is extracted in natural materials, is had no toxic side effect, and long-term taking is to people
Body has no adverse effects.The present composition makes capsule for reduction blood fat, services once sooner or later daily, each 3g, is within 10 days
One course for the treatment of.The material purity prepared with the method for the present invention in composition is high, can guarantee that the effect of reduction blood fat, the raw material of extraction
High income, it is easy to industrialized production, production process is without any pollution.

Lipid-lowering test：
1st, materials and methods
1.1 material
Animal used as test takes Wisrer rats 90, rat body weight 150-180g, male and female half and half.
1.2 method
90 rats are divided into into two groups, one group is raised for high lipid food, one group for normal diet raising.High lipid food
Increase sterling cholesterol 10%, lard 12%, sucrose 3% on the basis of normal diet.After high lipid food group is fed 15 days, blood drawing is surveyed
Determine serum total cholesterol and triglyceride, be randomly divided into high fat group, clofibrate group, the present composition implement 1 group, implement 5 groups,
Onion oil group, the present composition component implemented 1 group, implement 5 groups, is admixed in high lipid food daily by 85mg/kg consumptions,
Clofibrate group is admixed in high lipid food by 3.2mg/kg consumptions, and onion oil group is admixed in high lipid food by 85mg/kg consumptions, each group
Rat, each group rat free water are fed respectively.Blood fat was weighed and surveyed per 10 days.After successive administration 40 days, rat, abdomen are put to death
Vena cave takes blood, determines T-CHOL, triglyceride, HDL-C and low density cholesterol with full automatic biochemical apparatus and contains
Amount.
2nd, experimental result
The serum TC of each group rat（Cholesterol）、TG（Triglyceride）、HDL-C（HDL-C）、LDL-C
（LDL-C）Content is shown in Table 1.Test result indicate that：The serum TC of high fat group rat, TG and LDL-C concentration are equal
Apparently higher than normal diet group, HDL-C concentration is significantly lower than normal diet group.The blood of two groups of feed group rats of the present composition
Clear TC, TG and LDL-C concentration is significantly lower than high fat group, HDL-C concentration apparently higher than high fat group, and than clofibrate group rat
Serum TC concentration it is low, TG, LDL-C and HDL-C concentration is relatively.Test result indicate that, the present composition has substantially
Effect for reducing blood fat, lipid-lowering effect is close with the lipid-lowering effect of clofibrate, and experimental result shows simultaneously, the present composition
Lipid-lowering effect is substantially better than the lipid-lowering effect of onion oil, and synergy is notable.
