O. Kuntze vat. sinensis, and identified .as N-(2-hydroxyphenyl)-2-pyrrolidinone (1), p-hydroxyacetophenone (2), salicifoliol (3), (-)-3-hydroxy-/q-ionone (4), p-hydroxy ethyl ciunamate (5), ethyl 4-(sulfooxy)benzoate (6), (+)-matairesinol (7), (-)-pinoresinol (8), (+)-lirioresinol-A (9), and caffeine (10), among which compound 1 was isolated as a new natural product, and compound 6 was isolated from Theaceae family for the first time. Compounds 3, 4, 5, 7, 8, and 9 were isolated from this species for the first time.展开更多
