Also known as Amomum tsaoko Crevost et Lemaire (A. tsaoko), is a spice and medicinal fruit plant that can be used in daily human life for cooking health purposes. In Xishuangbanna (Yunnan Province, China) there an interesting phenomenon where the maximum Roxb. maximum) consumed by local people. The trade played significant role development of civilization histories nations. Both them have high edible value. identification classification metabolic components both are key to driving related industries. We SPME-GC–MS (Non-targeted headspace-solid phase microextraction-gas chromatography-mass spectrometry) its accurate qualitative quantitative performance, combined with multiple analytical methods, explain present fruits these two plants. Next, near-infrared (NIR) technology offers researchers advantage saving time being cost-effective. analyzed characteristic spectral chemical information NIR data. Identified relevant base group vibration mode. After analyzing data both, it was determined total 66 metabolites, 64 from cardamom 29 substance, showing 37 differences. Among 35 had significance level P ≤ 0.05 VIP ≥ 1, totaling 101 substances. This includes terpenes (37.9 %), aldehydes (12.1 organic heterocyclic compounds (7.6 alcohols (6.1 aromatic (4.5 esters ketones %). study validates species provides clear classification, which will beneficial future data-based applications fields food medicine.
