The present invention relates to a highly soluble composition containing cosmetic actives, its preparation and application, belonging to the technical field of cosmetics. The highly soluble composition containing cosmetic actives of the present invention comprises cosmetic actives and a solvent; the cosmetic actives are selected from one or more of glycyrrhetinic acid, asiatic acid and madecassic acid; the solvent comprises hexylene glycol, methyl glucamine and water. Methyl glucamine has multiple hydroxyl groups in its structure and has good water solubility. By combining the amino group in its structure with the carboxyl group on the cosmetic actives, the hydrophilicity of the cosmetic actives is increased. Hexylene glycol has the characteristics of being amphiphilic for oil and water and can play a bridging role in dissolving the cosmetic actives, promoting the combination of the cosmetic actives and methyl glucamine, thus playing a synergistic effect. At the same time, the amount of solvent used can be greatly reduced, and the dissolution efficiency of the cosmetic actives can be greatly improved, thereby realizing the application value in cosmetics.

The present invention belongs to the field of plant genetic engineering technology, and in particular to the application of a Centella asiatica glycosyltransferase gene in catalyzing the glycosylation of asiatic acid and madecassic acid. The nucleotide sequence of the gene is as shown in SEQ ID No.1, and the protein encoded by it can catalyze the C-28 position of asiatic acid and madecassic acid to carry out glucose group modification to produce asiatic acid monoglucoside and madecassic acid monoglucoside, and prefers catalysis madecassic acid. The present invention, by building a metabolic regulatory network, widely and accurately screens the above-mentioned gene, resolves the glycosylation process of catalyzing asiatic acid and madecassic acid, for the in vitro synthesis of Centella asiatica triterpenoid saponins and industrial production process to improve asiatic acid and madecassic acid glycosylation efficiency and asiaticoside and madecassin yield provide important reference basis, and provide important theoretical support for large-scale production of Centella asiatica active saponins.

The composition comprises an active component, a yeast fermentation product, a stabilizer, grease and polyol, wherein the active ingredients comprise a centella asiatica extract, ginsenoside and aescin; the centella asiatica extract comprises asiaticoside, madecassic acid and asiatic acid; the yeast fermentation product comprises at least one of sophorolipid and rhamnolipid. The composition provided by the invention has good high-temperature stability and grease compatibility, is high in bioavailability and good in grease compatibility, and has obvious effects of resisting wrinkles, tightening, fading dark circles and improving vascular dark circles.

The present invention discloses synergistic herbal compositions comprising combination of a first ingredient selected from Centella asiatica extract containing at least one component selected from magnesium salt or complex of asiatic acid and magnesium salt or complex of madecassic acid or mixtures thereof along with asiaticoside and madecassoside; and a second ingredient selected from extract, fraction, phytochemical or mixtures thereof derived from Theobroma cacao; process for their preparation, methods of treatment and use of such nootropic compositions for improving cognitive functions or mental abilities and gaming performance.

The present invention belongs to the technical field of biomedicine. Disclosed is an asiatic-acid-derived ceramide, which has the structure of general formula (I) or an isomer of general formula I, wherein R1 is selected from one of the following structures in (II), and R2 is hydroxyl or a hydrogen atom. Further disclosed in the present invention are a method for synthesizing the asiatic-acid-derived ceramide and the use thereof. By means of the present invention, the solubility of ceramide is improved by means of introducing an asiatic acid or madecassic acid fragment with good fat solubility, thereby facilitating the use of ceramide in formulations. The compound of the present invention exhibits a significant inhibitory effect on inflammatory cytokine interleukin-6 (IL-6), and can also suppress the overexpression of TRPV1 receptors in sensitive skin and significantly reduce the expression of hyaluronidase, thereby achieving a good soothing effect.

The invention discloses a madecassoside efficient preparation method based on yeast metabolic engineering and a madecassoside compound cosmetic composition. Three glycosyl transferases CaGlcT1, CaGlcT2 and CaRhaT are screened from a centella asiatica transcriptome, after the catalytic activity of the glycosyl transferases is verified, polygene co-expression is performed in saccharomyces cerevisiae, and madecassic acid can be catalyzed to synthesize madecassoside. After fermentation condition optimization and fed-batch fermentation, the conversion yield of madecassoside reaches 582 mg / L from 165 mg / L, 3.5 times of yield increase is achieved, the purity of obtained madecassoside reaches 95% or above, and commercial application and scientific research requirements are met. The obtained madecassoside is compounded with the chrysanthellum indicum extract and the purslane herb extract, so that the synergistic anti-oxidation and whitening effects are achieved. A new scheme is provided for green and intelligent manufacturing of cosmetic raw materials.
