Huaihua legumes Cassia dried flowers and buds . The former Xi called Huaihua , which Xi called the \Medical workers at home and abroad in recent years to study its role , its active ingredients have anti-cancer anti-cancer , anticoagulant , analgesic , anti-bacterial , anti-viral , anti-aging , anti-inflammatory , anti- allergic , anti-free radical and antioxidant other activity , improve myocardial circulation , detoxify, lowering blood pressure , soften blood vessels, anti-inflammatory kidney function , toxic to humans , harmless , non- lethal , carcinogenic , teratogenic , mutagenic effect . In this paper, the GC-MS analysis of the chemical composition of Huaihua essential oils , compared steam distillation and two methods of distillation and extraction method to extract the chemical composition of the essential oil content differences . Distillation and Extraction Method Huaihua essential oils , detachable 52 components , 43 compounds were identified , accounted for 98.49% of the peak area ; steam distillation only 41 components , 28 compounds were identified , the total peak area 84.53% . Agar diffusion method , the double dilution method , the inhibition curve method , turbidity analysis method to study the antibacterial activity of Huaihua essential oils of several common pathogens . The results of the agar diffusion method Huaihua essential oils against Staphylococcus aureus , Escherichia coli , Shigella Shigella , Salmonella typhi , single growth of Listeria monocytogenes and Wales Listeria monocytogenes target strain inhibition of Aspergillus niger and Candida albicans little inhibition ; by double dilution method the Huaihua essential oils of different strains of the minimum inhibitory concentration (MIC), Staphylococcus aureus and Listeria monocytogenes 0.39μL/mL,威尔斯李斯The special bacteria Salmonella typhi 0.78μL/mL, Shigella Shigella 1.56μL/mL , E. coli , hemolytic streptococcus and Salmonella paratyphi gt ; 25μL/mL . Finally, in advance with heat, acid , osmolarity , potassium sorbate , sodium benzoate , processing Staphylococcus aureus cells of different degree of stress , role then Sophorae essential oils found that the essential oils of the role of potassium sorbate cells for subsequent Sophorae sensitive role . Herald in the food processing industry , Huaihua essential oils can replace potassium sorbate to as fence inhibit the growth and reproduction of the pathogen , to improve food security .
