Main Technical Content: 4. Wild Breeding Base Site Selection 4.1 Determination of Acid Zizyphus Seed Content in Major Production Areas Across China and Shanxi Due to the inconsistent content of spinosin in acid zizyphus herbal materials across different regions and the frequent presence of unqualified content in some production areas, the selection of wild breeding sites should prioritize regions where the local content of acid zizyphus meets or exceeds standards. Considering that some breeding sites may require supplementary planting, it is essential to maintain consistent quality of acid zizyphus herbal materials by selecting local wild acid zizyphus as planting sources and sowing seeds or directly planting them in the breeding base. 4.1.1 Sample Collection In 2016, samples were collected from processing and distribution centers of acid zizyphus herbal materials. A systematic investigation of origin was conducted in 2017 to collect 74 samples (42 in 2016 and 32 in 2017). Using the content determination method established by the research team, the four main components—triterpenoid saponins (Zizyphus saponin A and B) and flavonoids (spinosin and 6′′-feruloylspinosin)—were measured. The source of the samples is shown in Tables 3–4. For 2016 samples: In late October (after the new harvest period of acid zizyphus, mid-August to early October), samples were collected from three major processing centers (Zhanhuan, Shandong; Wenshu, Shandong; and Neiqiu, Hebei) through the assistance of Zhongyao Tianandi Network and specialized merchants at these centers. Processed acid zizyphus herbal materials were collected from each processing merchant, with a minimum weight of 100 g per sample. For 2017 samples: From late September to early October, samples were collected directly from major production areas, with three sampling sites per area. Each sample came from over 20 individual plants, and approximately 20 fruits were collected from each plant. Three replicat
