Abstract

Farmers' varieties or landraces of chili are regularly heterogeneous, selected and preserved by small traditional farmers and highly demanded by regional consumers. The objective of this study was to evaluate the variation in the content of phenolic compounds, vitamin C, carotenoids, capsaicinoids and antioxidant activity in fruits of a population collection of the landraces Huacle and De Agua, which originated in Oaxaca, Mexico, and a commercial variety of Jalapeño (control). The collection was grown in greenhouse conditions under a random block design. At harvest, a sample of ripe fruits was obtained to evaluate the content of phenolic compounds, vitamin C and antioxidant activity by UV–visible spectrophotometry and the concentration of capsaicin and dihydrocapsaicin was measured by high-resolution liquid chromatography. Significant differences were observed between the Huacle and De Agua landraces and between these and Jalapeño. The studied fruits exhibit the following pattern for flavonoid and carotenoid contents: Huacle > De Agua > Jalapeño. The opposite pattern was observed for total polyphenol and vitamin C contents: Jalapeño > De Agua > Huacle. The general pattern for capsaicinoids in fruits was Jalapeño > De Agua > Huacle. Huacle and De Agua populations showed high variability in all compounds evaluated, with positive correlations with antioxidant activity. The capsaicin content in Huacle populations varied ranging from 7.4 to 26.2 mg 100 g-1 and De Agua ranged from 12.4 to 46.8 mg 100 g-1.

墨西哥土着社区保存的辣椒(Capsicum annuum L.)地方品种果实中的生物活性和营养成分

农民的辣椒品种或地方品种通常是异质的，由小型传统农民选择和保存，并受到区域消费者的高度需求。本研究的目的是评价原产于墨西哥瓦哈卡州的地方品种Huacle和De Agua和一个商业品种Jalapeño(对照)果实中酚类化合物、维生素C、类胡萝卜素、辣椒素和抗氧化活性的变化。该系列在随机块设计的温室条件下生长。采收时取成熟果实样品，用紫外可见分光光度法测定其酚类化合物、维生素C含量和抗氧化活性，用高分辨率液相色谱法测定辣椒素和二氢辣椒素的浓度。在Huacle和De Agua地方种族之间以及在它们和Jalapeño之间观察到显著的差异。所研究的水果类黄酮和类胡萝卜素含量呈现如下模式:Huacle > De Agua > Jalapeño。在总多酚和维生素C含量上观察到相反的模式:Jalapeño > De Agua > Huacle。辣椒素在水果中的一般模式为Jalapeño b> De Agua b> Huacle。Huacle和De Agua种群的所有化合物均表现出高变异性，与抗氧化活性呈正相关。Huacle群体辣椒素含量在7.4 ~ 26.2 mg 100 g-1之间，De Agua群体辣椒素含量在12.4 ~ 46.8 mg 100 g-1之间。
