Problems solved by technology

[0007] The main disadvantages of using the traditional method to test the above-mentioned types of wood are: 1> The inspection time is long, the traditional method needs to be combined with the macroscopic inspection and the anatomical characteristics of the wood, and the macroscopic inspection of the 12% air-dry density test of the wood takes about 3-7 days ;The process of softening, slicing, dehydration, and sealing in the inspection of wood anatomical characteristics takes 2-7 days
2> The inspection is a destructive inspection and uses a lot of materials. The traditional method density test requires at least 3 pieces of wood with a size of 2cm×2cm×2cm; the inspection of wood anatomical characteristics requires a piece of wood with a size of 3cm×3cm×1cm. For the damage of mahogany products serious
3> For wood with similar macroscopic and anatomical structures, the misjudgment rate is high
[0011] The method adopted by the patent application number 200910049820.9 is to connect the

Embodiment 1

[0052] The sample is 1 block of sandalwood red sandalwood (P.santalinus L.f.) marked as No. 1 block, and 2 blocks of dyed red sandalwood (P. tinctorius) marked as No. 2 block and No. 3 block.

[0053] 1. The pretreatment of the sample includes the following steps:

[0054] (1) choose respectively the representative position of these three pieces of wood, remove surface impurity;

[0055] (2) Scrape the wood test sample of 0.05g with a knife, transfer the wood test sample to a sealable test tube, add 10ml of chromatographically pure grade dichloromethane, soak at room temperature for 30min, and obtain the sample leaching solution;

[0056] (3) Take 5ml of the sample leachate and put it into a concentration bottle, concentrate it to about 2ml with nitrogen gas, filter it through an organic phase microporous membrane, and add the filtered concentrate into the sampling bottle of the chromatography-mass spectrometer.

[0057] 2. Obtain retention time-relative abundance spectrum an...

Embodiment 2

[0098] The test sample is to use sandalwood red sandalwood (P.santalinus L.f.) Buddha beads and dye rosewood (P.tinctorius) beads each for a comparative test, and the wooden blocks are respectively marked as No. 6 Buddha beads and No. 7 Buddha beads.

[0099] (1) No. 6 Buddhist beads and No. 7 Buddhist beads are polished with sandpaper to remove wax or impurities on their surfaces;

[0100] (2) Select the representative parts of the No. 6 and No. 7 beads and scrape 0.5g of the beads test sample with a knife and put them into a sealable test tube, add 10ml of chromatographically pure grade dichloromethane and soak for 30min at room temperature , to obtain sample leachate;

[0101] (3) Get 5ml of the sample leachate and put it into a concentrated bottle, concentrate it to about 2ml with nitrogen, filter through an organic phase microporous membrane, and add the filtered concentrated solution into the sampling bottle of the chromatography-mass spectrometer;

[0102] (4) The solu...

Abstract

The invention provides an identification method of pterocarpus santalinus wood and pterocarpus tinctorius wood and products of the pterocarpus santalinus wood and the pterocarpus tinctorius wood, which is capable of effectively overcoming the disadvantages of a traditional method for identifying pterocarpus santalinus and pterocarpus tinctorius that the consumed time is long, products of the pterocarpus santalinus and the pterocarpus tinctorius are seriously damaged, the misjudgment rate is high, and the like. The identification method comprises the following steps of pretreating a sample; carrying out GC-MS (Gas Chromatography-Mass Spectrometry) detection on the pretreated sample by utilizing a GC-MS (Gas Chromatograph-Mass Spectrometer), thus obtaining a retention time-relative abundance map and a mass spectrum, wherein parameters of the GC-MS are set as follows: the sample injection opening temperature is 255 DEG C to 275 DEG C, the flow division speed is 10 ml/min to 30.0 ml/min, the flow division time is 0.5 min to 3 min, the scanning interval is 0.3 s to 1.0 s, the MS transmission line temperature is 235 DEG C to 310 DEG C, and the ion source temperature is 235 DEG C to 315 DEG C; analyzing a molecular formula and the molecular weight of a compound which is obtained from a sample extract solution and is maximum in content, and further determining the variety of detected wood.

Description

technical field [0001] The invention belongs to the field of identification of wood species, and relates to an identification method of sandalwood red sandalwood and dyed red sandalwood based on the identification of characteristic compounds contained in the leachate of wood and its products. technical background [0002] Sandalwood red sandalwood (P.santalinus L.f.), also known as red sandalwood or lobular red sandalwood, is the first-class raw material for making furniture and handicrafts. Since the Ming Dynasty, it has always been used by Chinese royal nobles as a precious material for producing furniture or handicrafts. Sandalwood red sandalwood wood is tight and hard, calm, dignified, elegant, and noble. Its uniqueness and prominence in the history of furniture is incomparable to other woods, and it represents the deepest cultural heritage of the Chinese people. [0003] With the rapid development of my country's economy and the continuous improvement of living standard...
