Dataset of Major Quality Indicators and Mineral Elements of Peucedanum praeruptorum Harvested at Different Periods in Suiyang, Guizhou

Suiyang County, Zunyi City, Guizhou Province, is an important production area for white flowered Houttuynia cordata, but there is still a lack of systematic data on the formation of medicinal quality and the accumulation of mineral elements at different harvesting periods.

This study focuses on the same growth season and different harvesting periods of white flowered Peucedanum praeruptorum in Suiyang, Guizhou. The main quality indicators of the samples, such as moisture content, total ash content, acid insoluble ash content, and alcohol soluble extract, were determined according to the relevant methods in the 2025 edition of the Pharmacopoeia of the People's Republic of China (Part I); Using high-performance liquid chromatography (HPLC) to determine the content of Peucedanum praeruptorum A and Peucedanum praeruptorum B; Using the Kjeldahl method to determine nitrogen content; Using inductively coupled plasma optical emission spectroscopy (ICP-OES) to determine the content of 10 mineral elements including phosphorus, potassium, calcium, magnesium, sodium, iron, copper, zinc, manganese, and boron.
