Embodiment 1

[0024] Detection of volatile and semi-volatile chemical components of Dalbergia cochinchinensis:

[0025] Dalbergia cochinchinensis, commonly known as "Red Rosewood", according to the classification of the latest national standard of "Redwood" (GB / T 18107-2017), it belongs to the red sour tree category of Dalbergia genus, and it is the best wood in the red rosewood category. , The most widely used wood. It mainly grows in the Indochina Peninsula at 22°-10° north latitude, mostly in parts of Thailand, Cambodia, Laos, and Vietnam. It is usually dark red with black stripes (commonly known as black veins), and has a slightly sour aroma, which is very popular among consumers. The steps of utilizing the present invention to quickly detect the volatile and semi-volatile chemical components of Dalbergia cochinchinensis are as follows:

[0026] Pretreatment method: Weigh 50mg of Dalbergia cochinchinensis powder sample and place it in a 22mL headspace bottle, seal it with a bottle cap...

Embodiment 2

[0039] Detection of volatile and semi-volatile chemical components of Pterocarpus chinensis:

[0040] Big-fruit red sandalwood, also known as "Myanmar rosewood", according to the classification of my country's "Redwood" national standard (GB / T 18107-2017), it belongs to the rosewood of the genus Rosewood. It is a tall deciduous tree species, and the consumer market is relatively large. universal. It is mainly distributed in Indochina Peninsula (Myanmar, Laos, Thailand, Vietnam, Cambodia, western Malaysia and Singapore). The material is hard and heavy, with high density. Its heartwood is generally orange red, brick red, purple red, yellow or light yellow, often with dark stripes, and can emit a long-lasting and mellow sandalwood fragrance. Nowadays, it is easy to confuse Lao pears with Burmese pears in the market. In addition to the difference in wood color, the difference in aroma is also the main difference. Therefore, utilizing the present invention to quickly detect the vo...

Abstract

The invention discloses a detection method for determining volatile and semi-volatile chemical constituents of rosewood. Through a combination of a direct headspace solid phase microextraction pretreatment method and a full two-dimensional gas chromatography with high resolution, high throughout and peak capacity, convenient, accurate, fast and effective detection on volatile and semi-volatile chemical constituents of rosewood can be realized. The method is good in repeatability and high in analysis sensitivity after being verified by methodologies; the method can detect various volatile and semi-volatile chemical constituents in different kinds of rosewood; and the method is small in sample using amount, convenient in operation, fast in analysis speed, and suitable for fast analysis of large batch rosewood samples.

Description

technical field [0001] The invention relates to the technical field of mahogany analytical chemistry, in particular to a detection method for measuring volatile and semi-volatile chemical components of mahogany. Background technique [0002] As a rare wood, mahogany is a source of high-quality materials in furniture because of its good corrosion resistance, stability and sensory properties. Mahogany furniture is a typical representative of domestic high-end furniture. According to the latest national standard of "Redwood" (GB / T18107-2017), it is divided into 3 families, 5 genera, 8 categories and 29 tree species, from the original 33 tree species to 29, among which the red sandalwood belongs to the bird's foot in the rosewood class. Red sandalwood and Vietnamese red sandalwood are identified as big fruit red sandalwood, black rosewood in Dalbergia genus black rosewood is identified as knife-shaped black rosewood, Pengsai ebony in persimmon ebony is canceled, and hair medicin...
