Durian (Durio zibethinus M.) is a major economic fruit crop in Thailand. In this study, two popular cultivars, namely Chanee and Mon Thong, were collected from three orchards located in eastern Thailand. The pulp metabolome, including 157 annotated metabolites, was explored using capillary electrophoresis-time of flight/mass spectrometry (CE-TOF/MS). Cultivars and harvest years had more impact on metabolite profile separation than cultivation areas. We identified cultivar-dependent metabolite markers related to durian fruit quality traits, such as nutritional value (pyridoxamine), odor (cysteine, leucine), and ripening process (aminocyclopropane carboxylic acid). Interestingly, durian fruit were found to contain high amounts of γ-glutamylcysteine (810.3 ± 257.5 mg/100 g dry weight) and glutathione (158.1 ± 80.4 mg/100 g dry weight), which act as antioxidants and taste enhancers. This metabolite information could be related to consumer preferences and exploited for durian fruit quality improvement.

榴莲（Durio zibethinus（M.）是泰国的主要经济水果作物。在这项研究中，从泰国东部的三个果园中收集了两个受欢迎的栽培品种，即Chanee和Mon Thong。使用毛细管电泳-飞行时间/质谱（CE-TOF / MS）对纸浆代谢组（包括157种带注释的代谢物）进行了研究。品种和收成年限对代谢物谱分离的影响大于耕种区。我们确定了与榴莲果实品质性状相关的品种依赖的代谢物标记，例如营养价值（吡amine胺），气味（半胱氨酸，亮氨酸）和成熟过程（氨基环丙烷羧酸）。有趣的是，发现榴莲果实中含有大量的γ-谷氨酰半胱氨酸（810.3±257.5 mg / 100 g干重）和谷胱甘肽（158.1±80.4 mg / 100 g干重），用作抗氧化剂和增味剂。这种代谢产物信息可能与消费者的喜好有关，并被用于榴莲果实的质量改善。
