L. is a spiny fruit buttercup that is used in various traditional medicinal systems. In the current investigation of , the new chalcone 4-benzyloxylonchocarpin (), the new anthraquinone muracatanes A (), the new-to-nature anthraquinone muracatanes B (), and the new naphthalene analog muracatanes C () were isolated, in addition to the three previously reported compounds, 4-methoxylonchocarpin (), β-sitosterol (), and β-sitosterol β-D-glucopyranoside (). Their structures were elucidated using 1D (H and C) and 2D (COSY, HSQC, and HMBC) NMR spectroscopy and HR-ESI-MS. Chalcone showed potent acetylcholinesterase inhibitory effects with of 5.39 µM and of 3.54 µM, but none of the isolated compounds showed inhibitory activity towards butyrylcholinesterase. Anthraquinone illustrated α-glucosidase inhibitory effects with IC-values of 164.46 ± 83.04 µM. Compound displayed moderate cytotoxic activity towards ovarian carcinoma (A2780, IC = 25.4 µM), colorectal adenocarcinoma (HT29, IC = 20.2 µM), breast cancer (MCF7, IC = 23.7 µM), and thyroid carcinoma (SW1736, IC = 26.2 µM) while it was inactive towards pharynx carcinoma (FaDu: IC > 30 µM).
L. 是一种多刺的毛茛科植物，被用于各种传统医学体系中。在目前对 的研究中，分离得到了新查尔酮 4-苯甲氧基隆卡朋（）、新蒽醌 muracatanes A（）、新天然蒽醌 muracatanes B（）和新萘烷类似物 muracatanes C（），此外还有之前报道的三种化合物，4-甲氧基隆卡朋（）、β-谷甾醇（）和 β-谷甾醇-β-D-吡喃葡萄糖苷（）。它们的结构通过 1D（H 和 C）和 2D（COSY、HSQC 和 HMBC）NMR 光谱和 HR-ESI-MS 得到阐明。查尔酮 对乙酰胆碱酯酶表现出很强的抑制作用，其 IC₅₀值为 5.39 µM，IC₅₀值为 3.54 µM，但分离得到的化合物均对丁酰胆碱酯酶没有抑制活性。蒽醌 对 α-葡萄糖苷酶具有抑制活性，IC₅₀值为 164.46 ± 83.04 µM。化合物 对卵巢癌细胞（A2780，IC = 25.4 µM）、结肠直肠癌细胞（HT29，IC = 20.2 µM）、乳腺癌细胞（MCF7，IC = 23.7 µM）和甲状腺癌细胞（SW1736，IC = 26.2 µM）表现出中等的细胞毒性活性，而对咽癌细胞（FaDu：IC > 30 µM）则没有活性。
