Red mature calyces of were collected from 16 different locations in Meghalaya, India. Samples were processed using shade drying (SD) and tray drying (TD). NMR spectroscopy was used to assess the metabolic composition of the calyces. In this study, 18 polar metabolites were assigned using 1D and 2D NMR spectra, and 10 of them were quantified. Proximate analysis showed that the TD method is more efficient at reducing moisture and maintaining the ash content of the biomass. NMR metabolomics indicates that the metabolite composition significantly differs between SD and TD samples and is more stable in TD plant processing. The differences in post-harvest drying has a greater impact on the metabolite composition of than the plant location.

从印度梅加拉亚邦的 16 个不同地点收集了成熟的红色花萼。使用遮荫干燥（SD）和托盘干燥（TD）对样品进行处理。NMR 光谱用于评估花萼的代谢成分。在这项研究中，使用 1D 和 2D NMR 光谱分配了 18 种极性代谢物，并对其中的 10 种进行了定量。初步分析表明，TD 方法在降低水分和保持生物质灰分含量方面更有效。NMR 代谢组学表明，SD 和 TD 样品之间的代谢物组成存在显著差异，并且在 TD 植物加工中更稳定。收获后干燥方式的差异对的代谢物组成的影响大于植物产地的影响。
