  • Title: Identification of radical scavengers in sweet grass (Hierochloe odorata).
    Author: Pukalskas A, van Beek TA, Venskutonis RP, Linssen JP, van Veldhuizen A, de Groot A.
    Journal: J Agric Food Chem; 2002 May 08; 50(10):2914-9. PubMed ID: 11982419.
    Abstract:
    Extracts from aerial parts of sweet grass (Hierochloe odorata) were active DPPH free radical scavengers. The active compounds were detected in extract fractions using HPLC with on-line radical scavenging detection. After multistep fractionation of the extract, two new natural products possessing radical scavenging activity were isolated, and their structures were elucidated by NMR and MS. They were identified as 5,8-dihydroxybenzopyranone and 5-hydroxy-8-O-beta-D-glucopyranosyl-benzopyranone. Activities of the compounds isolated were tested by DPPH and ABTS free radical scavenging assays, and compared with the known natural antioxidant rosmarinic acid and Trolox.
