The invention discloses a blood-enriching motherwort plant extract and a skin care application thereof. The blood-enriching motherwort plant extract is prepared by adding water into angelica sinensis, astragalus membranaceus and motherwort and carrying out secondary heating reflux extraction and alcohol precipitation purification, active and effective components such as leonurine, calycosin-7-glucoside, ferulic acid and arteolide can be detected, and the blood-enriching motherwort plant extract is high in extraction rate, high and stable in component content and suitable for industrial production. The obtained blood-enriching motherwort plant extract is easy to dissolve in water, can be well and uniformly mixed with a collagen extracting solution, and is high in stability, simple in preparation process and more suitable for industrial mass production. The blood-enriching motherwort plant extract is compounded with a collagen extracting solution to prepare a mask, and compared with a common mask, the mask has moisturizing and repairing effects, remarkably improves the skin cuticle moisture content of a user, remarkably reduces the TEWL value and the TEWL / Corn value of skin transepidermal moisture loss of the user, effectively inhibits tyrosinase activity and has whitening and freckle removing effects.

This invention discloses a heparin trisaccharide compound, its preparation method, and its applications, belonging to the field of compound preparation technology. The heparin trisaccharide compound is mainly prepared by the following method: linking a monosaccharide donor and a disaccharide acceptor through glycosylation, then reacting in a methanol / sodium methoxide system or a tetrahydrofuran / sodium hydroxide / water system, followed by sequential O-sulfonation, catalytic hydrogenation, and N-sulfonation post-treatment steps to obtain the heparin trisaccharide compound. This compound has a well-defined structure, a single component, and exhibits anti-angiogenic activity and anti-tumor potential.
