Full description
The phytochemistry and antimicrobial activity of the newly identified Australian plant Olearia sp. Munro State Forest was examined. Antimicrobial TLC bioautography-guided isolation followed by NMR spectroscopy was used to identify the known compounds 8-O-β-D-xylopyranosyl-ent-8β-hydroxylabdan-15-oic acid (1) and pinocembrin (7), and new compounds 8-O-β-D-xylopyranosyl-ent-labdan-8β,15-diol (2) and ent-15-hydroxyclerod-3-en-17-oic acid (4a). Compounds without apparent activity in TLC bioautography included the previously undescribed ent-clerod-3-en-15,17-dioic acid (3a) and ent-cleroda-3,13-dien-15,17-dioic acid (5a), as well as known ent-8β-hydroxylabdan-15-oic acid (6) and penduletin (8). This is the first phytochemical and antibacterial study on this species of Olearia and has shown it to be an abundant source of ent-labdanes and ent-clerodanes.Issued: 2020
