The invention discloses a multi-element lycopene phosphatide compound and a preparation method thereof. The multi-element lycopene phosphatide compound is mainly prepared by natural multi-element lycopene and phosphatide, wherein the mass ratio of multi-element lycopene to phosphatide is 1:0.05-5. The multi-element lycopene phosphatide compound is safe and reliable, and can obviously increase the bioavailability of the multi-element lycopene.

The invention relates to a cosmetic product containing a GSH lipid nano-emulsion. The cosmetic is prepared from the following components in parts by weight: 0.05-5 parts of glutathione, 2-20 parts of phospholipid, 5-15 parts of oil, 1-25 parts of a non-ionic surfactant and 45-90 parts of dispersion medium; and the non-ionic surfactant is span 80, polyglycerin oleate, Tween 80, polyoxyethylated castor oil or polyethylene glycol caprylyl/capryl glucoside. According to the cosmetic provided by the invention, the glutathione is wrapped with a phospholipid microcapsule nano-emulsion; the lipid solubility of glutathione can be effectively increased; and more importantly, the transdermal absorption capacity of the glucoside is improved through a nanotechnology, so that application of the glucoside in the field of skin external use is enhanced.

The invention belongs to the technical field of compound preparation. The invention relates to a preparation method of phosphatidylglycerol monosodium salt, in particular to a preparation method of phosphatidylglycerol monosodium salt containing two different side chains. The preparation method comprises the following steps: taking D-mannitol as an initial raw material, heating D-mannitol in acetone to generate 1,1,5,6-isopropylidene-D-mannitol; carrying out sodium periodate oxidation and sodium borohydride reduction to obtain iso-propylidene glycerol; carrying out condensation reaction with fatty acid containing an R1 element, then removing acetal protective groups in the presence of acid; selectively protecting primary hydroxyl by using a silane protective agent, reacting secondary hydroxyl with another fatty acid containing a R2 element, removing silane protection, reacting the de-protected product with phosphorus oxychloride and iso-propylidene glycerol, removing acetal protectivegroups by using an acid, and finally carrying out a sodium salt treatment to obtain a final product. The synthesis of phosphatidyl monosodium salt containing two different side chains can be realized,and the production process is simple, environment-friendly and easy to operate.
