2. The whole plants of Dianthus superbus var. superbus were collected in July 2016 at Mount Kunyu, Shandong Province, and were authenticated by Prof. Jie Zhou from University of Jinan. A voucher specimen has been deposited at School of Biological Science and Technology, University of Jinan (Accession number: npmc-002). The plant materials (10 kg) were powdered and soaked with 95% ethanol (20 L × 4) at room temperature to obtain a crude extract (884 g), which was furthered processed by a series of chromatographic means to obtain alkaloids 1 (yield 0.0028%) and 2 (yield 0.0031%).
