Seven flavanones were identified from kino exudate of Corymbia torelliana by spectroscopic and spectrometric methods including UV, 1D and 2D NMR and UPLC-HR-MS. The study identified seven molecules, namely 3,4',5,7-tetrahydroxyflavanone (1), 3',4',5,7-tetrahydroxyflavanone (2), 4',5,7-trihydroxyflavanone (3), 3,4',5-trihydroxy-7-methoxyflavanone (4), (+)-(2S)-4',5,7-trihydroxy-6-methylflavanone (5), 4',5,7-trihydroxy-6,8-dimethylflavanone (6) and 4',5-dihydroxy-7-methoxyflavanone (7) from this eucalypt species. This is the first report of these natural products from C. torelliana kino exudate.
通过紫外光谱、一维和二维核磁共振以及超高效液相色谱-高分辨质谱等光谱和光谱测定方法，从托雷氏桉的儿茶素渗出物中鉴定出了七种黄烷酮。该研究从这种桉树种中鉴定出了七种分子，即3,4',5,7-四羟基黄烷酮（1）、3',4',5,7-四羟基黄烷酮（2）、4',5,7-三羟基黄烷酮（3）、3,4',5-三羟基-7-甲氧基黄烷酮（4）、(+)-(2S)-4',5,7-三羟基-6-甲基黄烷酮（5）、4',5,7-三羟基-6,8-二甲基黄烷酮（6）和4',5-二羟基-7-甲氧基黄烷酮（7）。这是首次从托雷氏桉儿茶素渗出物中报道这些天然产物。
