Abstract

The invention provides an application of veratryl fluorene acetal 4 in preparing anti-ultraviolet compositions, and further provides an anti-ultraviolet composition which contains veratryl fluorene acetal 4 as an active component and one or more kinds of auxiliary materials suitable for external use of skins.

Description

Technical field: [0001] The invention provides the application of a veratrum fluorene acetal in the preparation of an external anti-ultraviolet composition. Background technique: [0002] Veratramine A (Veratramine, CAS: 60-70-8), a chemical component of natural products, is isolated from the natural medicine veratrum, and has significant anti-tumor activity. [0003] [0004] Chinese patent CN200910052480.5 provides a veratramine degradation product, veratrol fluorene acetal 4, and discloses that it has a certain anti-tumor effect, but the effect is not obvious. [0005] Invention content: [0006] In the research, we found surprisingly that veratrol fluorene acetal 4 has the function of absorbing ultraviolet rays. [0007] The invention provides the application of the veratrum fluorene acetal 4 in the preparation of an anti-ultraviolet composition. [0008] The present invention also provides an anti-ultraviolet composition, which is characterized in that it cont...
