2026-09-17 Dataset of Major Quality Indicators and Mineral Elements of Peucedanum praeruptorum Harvested at Different Periods in Suiyang, Guizhou doi:10.57760/sciencedb.nprd.000c9 en The main quality components and mineral element content of Baihua Qianhu are important indicators for evaluating its medicinal quality, and its accumulation process is influenced by the growth stage and harvesting period. 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. The test results are uploaded to a public database in xlsx format. This dataset contains information on the main quality indicators, characteristic active ingredients, and mineral element content of Peucedanum praeruptorum at different harvesting periods. It can be used to compare the differences in the main quality indicators and mineral element content of Peucedanum praeruptorum at different harvesting periods, analyze their dynamic changes and interrelationships, and provide basic data support for the evaluation of Peucedanum praeruptorum harvesting periods, research on medicinal material quality, standardized production, and related data reuse in the Suiyang production area of Guizhou.  Peucedanum praeruptorum Dunn; harvest time; mineral elements; quality indicators; dataset yu lang Luo Chunli PUBLIC https://creativecommons.org/licenses/by/4.0/ dataset Science Data Bank
