Two new acetyl C-glucoside flavonoids, 8-C-beta-D-(2"-O-acetyl)glucofuranosylapigenin and 3"-O-acetylvitexin, along with four known C-glucoside flavonoids, vitexin, 6"-O-acetylvitexin, 2-O-acetylvitexin, and 2"-O-rhamnosylvitexin were isolated from the leaves of Crataegus pinnatifida Bge. var. major N.E.Br. Their structures were elucidated by spectroscopic means and chemical evidence.
从山里红（Crataegus pinnatifida Bge. var. major N.E.Br.）的叶子中分离出两种新的乙酰基 C-葡萄糖苷黄酮类化合物，8-C-β-D-(2''-O-乙酰基)葡萄糖呋喃糖基芹菜素和 3''-O-乙酰基牡荆素，以及四种已知的 C-葡萄糖苷黄酮类化合物，牡荆素、6''-O-乙酰基牡荆素、2-O-乙酰基牡荆素和 2''-O-鼠李糖基牡荆素。通过光谱手段和化学证据对它们的结构进行了阐明。
