Sapota, L., are tasty, juicy, and nutrient-rich fruits, and likewise used for several medicinal uses.
The current study represents an integrated metabolites profiling of sapota fruits pulp GC/MS and UPLC/MS, alongside assessment of antioxidant capacity, pancreatic lipase (PL), and α-glucosidase enzymes inhibitory effects.
GC/MS analysis of silylated primary polar metabolites led to the identification of 68 compounds belonging to sugars (74%), sugar acids (18.27%), and sugar alcohols (7%) mediating the fruit sweetness. Headspace SPME-GC/MS analysis led to the detection of 17 volatile compounds belonging to nitrogenous compounds (72%), ethers (7.8%), terpenes (7.6%), and aldehydes (5.8%). Non-polar metabolites profiling by HR-UPLC/MS/MS-based Global Natural Products Social (GNPS) molecular networking led to the assignment of 31 peaks, with several novel sphingolipids and fatty acyl amides reported for the first time. Total phenolic content was estimated at 6.79 ± 0.12 mg gallic acid equivalent/gram extract (GAE/g extract), but no flavonoids were detected. The antioxidant capacities of fruit were at 1.62 ± 0.2, 1.49 ± 0.11, and 3.58 ± 0.14 mg Trolox equivalent/gram extract (TE/g extract) DPPH, ABTS, and FRAP assays, respectively. enzyme inhibition assays revealed a considerable pancreatic lipase inhibition effect (IC = 2.2 ± 0.25 mg/mL), whereas no inhibitory effect towards α-glucosidase enzyme was detected. This study provides better insight into sapota fruit's flavor, nutritional, and secondary metabolites composition mediating for its sensory and health attributes.
人心果是一种美味、多汁且营养丰富的水果,同样也被用于多种药用用途。
本研究代表了人心果果肉的综合代谢物分析,采用 GC/MS 和 UPLC/MS,以及抗氧化能力、胰脂肪酶 (PL) 和 α-葡萄糖苷酶抑制效果的评估。
对硅烷化初级极性代谢物的 GC/MS 分析导致鉴定出 68 种化合物,属于糖 (74%)、糖酸 (18.27%) 和糖醇 (7%),调节水果的甜度。顶空 SPME-GC/MS 分析导致检测到 17 种挥发性化合物,属于含氮化合物 (72%)、醚 (7.8%)、萜烯 (7.6%) 和醛 (5.8%)。通过 HR-UPLC/MS/MS 基于全球天然产物社交 (GNPS) 分子网络的非极性代谢产物分析导致分配 31 个峰,其中一些新型神经酰胺和脂肪酸酰胺首次报道。总酚含量估计为 6.79 ± 0.12 毫克没食子酸当量/克提取物 (GAE/g 提取物),但未检测到类黄酮。水果的抗氧化能力分别为 1.62 ± 0.2、1.49 ± 0.11 和 3.58 ± 0.14 毫克 Trolox 当量/克提取物 (TE/g 提取物) DPPH、ABTS 和 FRAP 测定。酶抑制测定显示出相当大的胰脂肪酶抑制作用 (IC = 2.2 ± 0.25 毫克/毫升),而对 α-葡萄糖苷酶没有抑制作用。本研究提供了对人心果水果风味、营养和次生代谢物组成的更好了解,调节其感官和健康属性。
