    Ultrasonic extraction of ascorbic acid from indigenous leaves prior to detection by fluorescence spectroscopy by A. Bakar, Nurul Farehah, Sulaiman, Azli

    Published 2018
    “…Samples of indigenous leaves such as tenggek burung (Euodia redlevi), ulam raja (Cosmos Caudatus) and pegaga (Centella asiatica) were extracted by an ultrasonic extraction technique prior to the determination of ascorbic acid by fluorescence spectroscopy. The extraction parameters such as types of solvent, concentration of solvent, time of extraction, temperature of extraction and sample weight were optimized. …”
