Abstract

The invention discloses an HPLC standard fingerprint of pterocarpus santalinus. The HPLC standard fingerprint has six characteristic peaks, wherein the peak area of the characteristic peak with the longest retention time is the largest; by taking the characteristic peak with the largest peak area as the reference pea, the relative retention times tg of the six characteristic peaks are respectively0.085, 0.099, 0.133, 0.160, 0.271 and 1.000, and RSD% is less than 2%. The invention also discloses a constructing method of the fingerprint. The HPLC standard fingerprint of pterocarpus santalinus established by the invention can effectively identify the authenticity of pterocarpus santalinus by similarity analysis and comparison of characteristic peaks.

Description

technical field [0001] The invention belongs to the technical field of wood identification, and relates to a sandalwood red sandalwood HPLC (high performance liquid chromatography) standard fingerprint and its construction method and application. application. Background technique [0002] Sandalwood red sandalwood (Pterocarpus santalinus) is a Papilionaceae, Pterocarpus trees, also known as Indian small leaf red sandalwood. Arbor, 8 to 11 meters high, mainly produced in India. Solid and thick, fine wood, high density, resistant to carving, dark purple or black purple in color. Sandalwood red sandalwood grows extremely slowly, and it takes hundreds or even thousands of years to grow. Because of its extremely low yield rate and scarcity of resources, it is expensive and ranks first among all trees. Driven by huge profits, counterfeit products of sandalwood and red sandalwood are rampant. How to accurately identify sandalwood red sandalwood has become the biggest problem in...
