Embodiment

[0038] (1) Preparation of Herba chinensis extract

[0039] The washed Dabai leaves are dried at 60° C. with a blower dryer, pulverized by a mechanical pulverizer and passed through a 60-mesh sieve to obtain Dabai leaf powder. Accurately weigh 10.0kg of Dabaibu powder and put it into supercritical CO 2 The extraction kettle of the extractor carries out CO 2 supercritical extraction. Supercritical CO 2 The antibacterial components of Dabaibu were extracted by extraction method, the extraction process was extraction pressure 25MPa, extraction temperature 52°C, CO 2 The flow rate was 100g / min, the extraction time was 1.0h, and 632g of the green oily extract was collected in the separation kettle, and the extraction rate was 6.32%. Store the samples in a 4°C refrigerator for later use.

Abstract

The invention belongs to the field of natural preservatives and discloses a natural botanical preservative and a preparation method and application thereof. The natural botanical preservative is prepared from, by mass, 10-25% of a stemona tuberosa extract, 10-25% of an eleutherine plicata extract, 10-25% of a litsea cubeba extract, 10-25% of a murraya paniculata extract and 30%-60% of a solvent. The natural botanical preservative is composed of botanical complex extract obtained by supercritical CO2 extraction in four plants including murraya paniculata, stemona tuberosa, eleutherine plicata and litsea cubeba, a synergistic effect is achieved, an antibacterial spectrum of each single plant is expanded to achieve a wide antibacterial spectrum, and effectiveness in inhibition of microbes including escherichia coli, pseudomonas aeruginosa, staphylococcus aureus, bacillus subtilis, candida albicans, aspergillus niger and the like is achieved, so that the natural botanical preservative canbe applied to the field of cosmetics.

Description

technical field [0001] The invention belongs to the field of natural preservatives, in particular to a natural plant source preservative and its preparation method and application. Background technique [0002] The demands of contemporary consumers for cosmetics are "safe, effective and mild". In order to meet the demand, a large amount of natural and organic nutrients and water need to be added to cosmetics. These highly nutritious additives create more convenient conditions for the reproduction of microorganisms, which may cause cosmetics to deteriorate. Therefore, a certain amount of preservatives need to be added in cosmetics to inhibit the metabolism of bacteria, molds and yeasts and affect their growth and reproduction. [0003] With the emergence of "natural, organic, and preservative-free" consumer demands, traditional chemically synthesized preservatives that have certain toxicity due to their structure and properties have been gradually replaced by safer preservat...
