Synthesis and Activity Test of Coumarin-Chalcone Derivative as a Colorimetric Sensor for Chicken Spoilage Indicator

摘要

Chemosensor of coumarin-chalcone (2) derivative has been synthesized and tested for chicken spoilage indicator. The compound (2) was synthesized from the reaction of 3-acetyl-2H-chromen-one (1) and vanillin with reflux and ultrasonic irradiation methods. The compound (2) exhibited quick and obvious color in sensor label for amines from yellow to dark yellow. Application to detect spoiled chicken showed that color of compound (2) changed at 12 h and 6 d in room and chiller temperature respectively. Thus, compound (2) can be used efficiently for decayed chicken detection.
