The chili pepper is highly valued for its pungency and nutritional value, in addition to being a good source of phenolic compounds. Several factors affect the production of phenolics in the plant, including plant regulators. In this context, the present work aims to evaluate the influence of ABA, GA₃, and SA in the production of phenolic compounds in Capsicum frutescens. It was applied 10 mmol L⁻¹ of ABA, 144 mmol L⁻¹ of GA₃, 2000 mmol L of SA⁻¹ and the control (C) (solution without regulators) in fruits of C. frutescens. The results show that chili pepper presented a good variety of phenolics, ranging from phenolic acids (benzoic and cinnamic acids) to flavonoids (flavonols and flavan-3-ols) and that phenolic concentrations were significantly altered in fruits treated with GA₃, ABA and SA compared to control fruits. In addition, the PCA and HCA separated the samples into three groups, C, ABA, and a group with GA₃ and SA, with the ABA group having the highest phenolic content and the C group the lowest. Plant regulators (GA₃, ABA and SA) influence the synthesis of phenolic compounds in C. frutescens fruits.

除了作为酚类化合物的良好来源外，辣椒还因其辛辣味和营养价值而备受推崇。有几个因素会影响植物中酚类物质的生产，包括植物调节剂。在此背景下，本工作旨在评估 ABA、GA ₃和 SA 对辣椒中酚类化合物生产的影响。将 10 mmol L ^-1 ABA、144 mmol L ^-1 GA ₃、2000 mmol L SA ^-1和对照（C）（不含调节剂的溶液）应用于C. frutescens果实中. 结果表明，辣椒具有多种酚类物质，从酚酸（苯甲酸和肉桂酸）到类黄酮（黄酮醇和 flavan-3-ols），并且用 GA ₃、ABA 和SA 与对照水果相比。此外，PCA 和 HCA 将样品分为三组，C、ABA 和 GA ₃和 SA 组，其中 ABA 组的酚类含量最高，C 组最低。植物调节剂（GA ₃、ABA 和 SA）影响C. frutescens果实中酚类化合物的合成。
