Aurantii fructus (zhiqiao, ZQ) is a traditional Chinese medicine (TCM) and raw material of TCM healthcare food (TCM-HF), mainly focused on the regulation of gastrointestinal disorders and the abundant application of antioxidants. Pharmacological investigations of ZQ flavonoids have identified them as the main bioactive components in recent years, but little has been reported on the extraction processes of antioxidant flavonoids (AFs). The aim of this study was to establish an efficient ultrasonic-assisted extraction (UAE) method for the extraction of AFs from ZQ using a response surface methodology (RSM), analyze the composition of AFs, and develop a qualitative evaluation method for ZQ. Flavonoid yield and antioxidant ability were selected as the responses to optimize the extraction of AFs, and the multiple effects of independent variables were investigated. The optimized conditions for the extraction of AFs based on the Box-Behnken design (BBD) were as follows: ethanol concentration, 58%; extraction temperature, 70 °C; and extraction time, 17 min. The flavonoid yield and antioxidant activity reached 241.70 mg/g and 59.42%, respectively, which matched the predicted values. Furthermore, optimized UAE processes were first established for the efficient and fast extraction of AFs. Flavanones and polymethoxyflavonoids (PMFs) were identified as potential AFs using time-of-flight mass spectrometry. Meanwhile, the quality of ZQ was evaluated using the criteria importance through intercriteria correlation (CRITIC) method for the first time, and Yuanjiang ZQ was considered as an excellent raw material of TCM-HF.

Ultrasonic Assisted Extraction

Moringa oleifera is considered one of the most useful plants in the world because it's rich in bioactive substances, which employing on modern medical treatment, also can be used for many fields: pharmaceutical, food and cosmetics purposes. In this study, the response surface methodology (RSM) based on a Box–Behnken design (BBD) was employed to optimize the extraction time (X1: 20–60 min), extraction temperature (X2: 15–45 °C) and solvent-solid ratio (X3: 5–7 ml/g), to obtain a high crude of flavonoids yield from Moringa oleifera Leaves by ultrasonic-assisted extraction technique (UAE). The optimum conditions were an extraction time 23 (min), extraction temperature 44 (°C) and solvent-solid ratio 5.05 (ml/g). Under these conditions, the experimental yield was 72.65 (mg ER/g), well matched with the predicted yield 74.34 (mg ER/g) with the coefficients of determination (R2= 0.9861), thus indicating the suitability of response surface methodology in optimizing the ultrasound-assisted extraction of flavonoids from Moringa oleifera Leaves.

Ultrasonic Assisted Extraction

An efficient ultrasonic-assisted extraction of inulin from Jerusalem artichoke was investigated by Response Surface Methodology (RSM). The results showed that the yield of ultrasonic-assisted extraction was 62.07 ± 0.39% over the microwave (40.85 ± 0.28%) and hot water extraction (27.42 ± 0.42%). The Box-Behnken Design (BBD) was used to optimize the effects of three parameters (temperature-X1, ultrasonic power-X2 and time-X3) on inulin yield. Analysis of variance showed that the contributions of X1, X3, X12, X13, X22 were significant. The optimal yield of inulin was 82.93 ± 1.03% at 82 °, 120 W and 18 min.
