Hongmu, a Chinese customary noun representing 29 kinds of wood species such as some species (abbreviated as spp. hereinafter), spp. and spp., is popular among Chinese people due to the furniture made from it. The slow regeneration of hongmu resources led to a decline in production, making hongmu prices high and illegal businesses profit from it. Therefore, it is necessary to identify and distinguish different varieties of hongmu for commercial trade. Herein, a cost-effective and rapid methodology was first developed atmospheric pressure glow discharge mass spectrometry (APGD-MS) to classify three spp. and three spp. Meanwhile, principal component analysis (PCA) was further applied to distinguish wood species and six kinds of hongmu extracts were able to be approximately separated into six units. Besides, hongmu could be clearly distinguished from their counterfeits, such as spp., using the method provided here. This method may provide a timely and necessary way for the determination of ingredients and identification of the authenticity of hongmu.
红木，一个中国传统名词，代表了 29 种木材，如一些 种（简称 spp.）、spp. 和 spp.，由于用其制成的家具，在中国广受欢迎。红木资源的再生缓慢导致产量下降，使红木价格居高不下，非法商家从中获利。因此，有必要对不同品种的红木进行识别和区分，以便进行商业交易。在此，首次开发了一种具有成本效益和快速的方法——常压辉光放电质谱（APGD-MS）来对三种 spp.和三种 spp.进行分类。同时，进一步应用主成分分析（PCA）来区分木材种类，六种红木提取物能够大致分为六个单元。此外，通过提供的方法，可以将红木与其假冒品，如 spp.，清晰地区分开来。该方法可能为确定红木的成分和鉴定其真伪提供及时和必要的途径。
