The aim of this study was to evaluate the use of the peach palm by-product to obtain extracts rich in total phenolic compounds (TPC) and soluble sugars (SS), using the subcritical water extraction (SWE) method. The results obtained by Box-Behnken factorial design showed that temperature and time variables have higher effect in the removal of TPC and SS, than pressure. At 100 bar, 130 °C and 90 min the highest extraction of SS (14.65 g 100 g⁻¹) and TPC (921.50 mg 100 g⁻¹) were achieved, ​​representing increases by factors of 1.2 and 2.5, respectively, when compared to the values obtained applying conventional extraction procedures: orbital and magnetic continuous stirring. In the extract obtained by SWE (100 bar, 130 °C and 90 min), highest values of antioxidant activity, fructose, glucose and phenolic acids were detected. Therefore, SWE can be used to promote the use and valorization of the peach palm by-product.

这项研究的目的是通过亚临界水萃取（SWE）方法评估桃棕榈副产品用于获得富含总酚类化合物（TPC）和可溶性糖（SS）的提取物的用途。Box-Behnken析因设计获得的结果表明，温度和时间变量对TPC和SS的去除效果要好于压力。在100巴，130°C和90分钟的条件下，SS（14.65 g 100 g ^-1）和TPC（921.50 mg 100 g ^-1）的最高提取率），与使用常规萃取程序（轨道和磁力连续搅拌）获得的值相比，分别增加了1.2和2.5倍。在通过SWE（100 bar，130°C和90分钟）获得的提取物中，检测到了最高的抗氧化剂活性，果糖，葡萄糖和酚酸值。因此，SWE可用于促进桃棕榈副产物的使用和增值。
