Abstract:

Nineteen compounds including one new flavanone were isolated from the juice of aged common sage exudate with sugar (ACSE). The isolated compounds were identified by NMR and MS analyses as levodopa methyl ester (1), 3,4-dihydroxybenzoic acid (2), (S)-8-hydroxy-4-hydroxy-phenylpropanoic acid (3), 4-hydroxybenzoic acid ethyl ester (4), cis-caffeic acid (5), trans-caffeic acid (6), esculetin (7), (S)-8-hydroxy-3,4-dihydroxy-phenylpropanoic acid ethyl ester (8), cis-rosmarinic acid (9), trans-rosmarinic acid (10), trans-rosmarinic acid methyl ester (11), 6-methoxy-7,8,3',5'-tetrahydroxyflavanone (12), nepetin (13), trans-caffeic acid ethyl ester (14), luteolin (15), cis-caffeic acid ethyl ester (16), 6-methoxynaringenin (17), 1α-acetoxy-2-oxo-eudesman-3,7(11)-dien-8β,12-olide (18), and hispidulin (19). Compound 12 was isolated for the first time from nature and seven compounds (1, 3, 4, 7, 8, 14, and 18) were newly identified from common sage. Of them, 15 isolated phenolic compounds (1-3, 5-8, 10-15, 17, and 19) were detected in ACSE juice, while only 10 was detected in the fresh common sage.
