Application of the herbal chemical marker ranking system (Herb MaRS) to the standardization of herbal raw materials: a case study.

Introduction: Phytochemical standardization of herbal materials involves establishing consistent levels of one or more active ingredients or markers. It ensures the authenticity and quality of herbal materials, extracts, and their products. This research aimed to apply the herbal chemical marker ranking system (Herb MaRS) originally proposed for quality assurance of complex herbal products to establish markers for controlling the quality of herbal raw materials.

Chemometric Classification of L. Leaf Cultivars, Based on Selected Phytochemical Parameters; Implications for Standardization of the Pharmaceutical Raw Materials.

Introduction: leaves are among the most common materials employed in manufacturing herbal medicinal products. Despite the phytochemical variation of cultivars, there are no monographs to guide the cultivation, processing, and authentication of the materials.

Methods: This study characterized 15 Ugandan leaf varieties, with reference to extraction index (EI), total phenolic content (TPC), antioxidant activity (AOA), and mangiferin concentration (MC).
