Embodiment 1

[0028] Embodiment 1, the preparation of perilla extract, mountain silver flower extract and Jiulixiang extract

[0029] In this example, the experimental raw materials of perilla, mountain silver flower, and Jiulixiang were purchased from the common people's pharmacy. Prepare perilla extract, mountain silver flower extract and Murata extract respectively according to the following methods:

[0030] The perilla extract is extracted according to the following method: the dried perilla stems and leaves are ground and crushed and then passed through a 40-mesh sieve. According to the ratio of 50 mL of extraction solvent per gram of perilla stems and leaves, 90% concentration of ethanol is used as Extract the solvent, reflux at 65°C for 2-3 hours, filter, collect the filtrate, and record it as the first filtrate; add ethanol with a concentration of 90% that is basically the same volume as the first filtrate to the filter residue, and use the same volume as the first filtrate to extr...

Abstract

The invention provides a plant bacteriostatic composition and application thereof in a liquid detergent. The composition is compounded by perillae extracts, flos lonicerae extracts and murraya paniculata extracts. The composition has a good bacteriostatic effect, in particular, has a synergistic effect in the aspect of suppressing staphylococcus aureus, Escherichia coli, pseudomonas aeruginosa, aspergillus niger and candida albicans. The bacteriostatic composition can be applied to the liquid detergent to realize a bacteriostatic effect, so that the additive amount of chemosynthetic preservatives is reduced, and the expiration date of products is ensured to be unchanged.

Description

technical field [0001] The invention relates to a plant antibacterial composition, in particular to a plant antibacterial composition which is added to laundry detergent and has antibacterial effect, and belongs to the field of daily chemical additives. Background technique [0002] Laundry detergent is a commonly used daily chemical product. The laundry detergent sold on the market is mainly prepared by adding several surfactants and additives. It can only play the role of decontamination, and often contains preservatives and / or bacteriostats. At present, preservatives and / or bacteriostats commonly used in laundry detergent include methylisothiazolinone, chloromethylisothiazolinone, DMDM ​​hydantoin, etc., although these preservatives can play a role in antibacterial and antibacterial mildew, etc., but these products have major disadvantages, such as high cost of urea, poor water solubility, complicated use, not suitable for large-scale use; and these preservatives are not ...
