1H NMR 分析共检测到 53 种代谢物，主要分为有机氧化合物、羧酸及其衍生物等 11 类。 PCA 结果显示，抗病组与感病组的代谢谱存在显著分离，而抗病组与对照组聚类接近，表明抗病油棕在感染后仍能维持类似健康植株的代谢稳态。

NMR波谱按照测定对象分类可分为：1H-NMR谱（测定对象为氢原子核）、13C-NMR谱及氟谱、磷谱、氮谱等。 有机化合物、高分子材料都主要由碳氢组成，所以在材料结构与性能研究中，以1H谱和13C谱应用最为广泛。

低场 1 H NMR 光谱技术具有设备成本低、操作简便、无需复杂维护等优点，相比传统的高场 NMR 更易普及。 它作为一种代谢组学筛查工具，有望弥补传统筛查方法的不足，提高宫颈癌早期诊断的准确性，从而帮助更多女性在疾病早期得到及时治疗，改善预后，降低宫颈癌的发病率和死亡率，为女性健康保驾护航。
