摘要

本研究调查了莫桑比克四种野生食用水果的抗氧化化合物和抗氧化能力的变化:Adansonia digitata (AD)、Dialium schlechteri (DS)、Garcinia livingstonei (GL) 和 Syzygium cordatum (SC)。采用分光光度法测定了抗氧化化合物,包括总多酚含量(TPC)、总黄酮含量(TFC)和维生素 C,以及三种方法(DPPH、ABTS 和 FRAP)得出的总抗氧化能力(TAC)。以干基计,TPC 的结果范围为 42.8 ± 1.05 至 65.4 ± 0.51 毫克 GAE/克,TFC 为 8.6 ± 0.03 至 66.7 ± 1.41 毫克 RE/克,维生素 C 为 1.7 ± 0.28 至 40.1 ± 0.35 毫克/100 克。TAC-DPPH 为 53.5 ± 1.80 至 88.3 ± 0.29 μmol TE/g,TAC-ABTS 为 52.8 ± 0.50 至 136.7 ± 0.97 μmol TE/g,TAC-FRAP 为 12.4 ± 0.79 至 75.0 ± 2.32 μmol TE/g。AD 的 TPC 和维生素 C 含量最高,表明其抗氧化能力较强。值得注意的是,年变化对抗氧化化合物的影响比地点变化更明显。研究发现,南卡罗来纳州的全氯化物和亚得里亚海地区的维生素 C 的年变化率约为 30%。尽管存在这些差异,这些未充分利用的水果仍具有潜在的营养和健康益处,可用于食品开发。

Variability of antioxidant compounds and capacities in four wild fruits collected in different years and locations in Mozambique

This study investigated the variability of antioxidant compounds and capacity of four wild edible fruits from Mozambique: Adansonia digitata (AD), Dialium schlechteri (DS), Garcinia livingstonei (GL), and Syzygium cordatum (SC), collected over three consecutive years from seven locations. Antioxidant compounds including total polyphenol content (TPC), total flavonoid content (TFC), and vitamin C, as well as the total antioxidant capacity (TAC) by three methods (DPPH, ABTS, and FRAP) were determined by spectrophotometric methods. Results in dry basis for TPC ranged from 42.8 ± 1.05 to 65.4 ± 0.51 mg GAE/g, TFC from 8.6 ± 0.03 to 66.7 ± 1.41 mg RE/g and, vitamin C from 1.7 ± 0.28 to 40.1 ± 0.35 mg/100 g. TAC-DPPH ranged from 53.5 ± 1.80 to 88.3 ± 0.29 μmol TE/g, TAC-ABTS from 52.8 ± 0.50 to 136.7 ± 0.97, μmol TE/g, and TAC-FRAP from 12.4 ± 0.79 to 75.0 ± 2.32 μmol TE/g. AD exhibited the highest TPC and vitamin C, indicating higher antioxidant capacity. Notably, yearly variations had a more pronounced impact on antioxidant compounds than locations. It was found a yearly variation of about 30 % for TFC in SC and vitamin C in AD. Despite these variations, these underutilized fruits hold potential nutritional and health benefits and can be used in food product development.
