Six polyphenolic acids (1–6), including the three new compounds citriodolic acids A, B, and C (1–3), were isolated from the leaves of Eucalyptus citriodora. Their structures were elucidated by spectroscopic methods including one dimensional (1D)- and 2D-NMR, high-resolution electrospray ionization (HR-ESI)-MS, and circular dichroism (CD). The potential antivirus activity against respiratory syncytial virus (RSV) of all the isolated compounds was evaluated.
从柠檬桉叶中分离出六种多酚酸(1-6),包括三种新化合物柠檬酚酸 A、B 和 C(1-3)。通过一维(1D)和二维核磁共振(2D-NMR)、高分辨率电喷雾离子化(HR-ESI)质谱(MS)和圆二色光谱(CD)等光谱方法阐明了它们的结构。评估了所有分离化合物对呼吸道合胞病毒(RSV)的潜在抗病毒活性。
