Microwave-enhanced extraction and mass spectrometry fingerprints of polyphenolic constituents in sesamum indicum leaves

Sesamum indicum is an important commodity plant that is highly valued for its distinctive flavor, nutritional and medicinal function. The polyphenolic constituents in sesame leaves is responsible for its numerous medicinal and nutritional properties. Unfortunately, the extraction of bioactive consti...
