摘　　要：Food agricultural waste from fruit products such as rinds can be one source of environmental pollution.Therefore,the study was conducted to investigate the total phenolic content,total flavonoid content,antioxidant property,and chemical profiling using gas chromatography-mass spectrometer(GC-MS)and high-performance liquid chromatography tandem mass spectrometry of triple quadrupole(HP LCMS-MS QTOF).Ultrasoundassisted extraction for 45 min was used as a green technique to extract bioactive compounds from watermelon(Citrullus lanatus)and wintermelon(Benincasa hispida)rinds.The total phenolic content and total flavonoid content of ultrasound-assisted extraction were compared with maceration technique.As revealed by the results,maceration technique had a lower total phenolic content for both C.lanatus rind(7.07±0.86μg GAE/mg)and B.hispida rind(13.87±0.11μg GAE/mg)compared to ultrasound-assisted extraction.The similar trends can be observed in total flavonoid content of C.lanatus rind(4.97±0.29μg RE/g)and B.hispida rind(8.30±0.17μg RE/g)by maceration which showed a lower quantity compared to ultrasound-assisted extraction.The ultrasound-assisted extraction was selected for further analysis.The total phenolic content assay found that the B.hispida rind extract exhibited higher total phenolic content values(23.39±0.22μg GAE/mg),than C.lanatus rind extract(15.10±0.58μg GAE/mg).B.hispida rind extract had a higher total flavonoid content(11.17±0.17μg RE/g)than C.lanatus rind extract(6.16±0.09μg RE/g).The antioxidant activity was investigated using DPPH scavenging assay.The antioxidant capacity of B.hispida rind extract(20872.19±1301.47 mg/mL)stronger compared to C.lanatus rind extract(23514.47±678.70 mg/mL).Results revealed that there was a negative correlation between total phenolic content,total flavonoid content,and DPPH scavenging activity IC50.The phytoconstituent determination in B.hispida and C.lanatus rind extract showed both contained phenolic,malic acid,and other compounds that might have contri
