Abstract:
ObjectiveThe quality of fresh Gastrodiae Rhizoma directly determines the efficacy of its terminal products. According to the theory of excellent shape， high quality， and superior effect of authentic medicinal materials， this study aimed to develop a novel quality evaluation system for fresh Gastrodiae Rhizoma by systematically quantifying and integrating appearance traits with bioactive components. MethodsFresh Gastrodiae Rhizoma samples were collected from four major producing regions. After herbal textural research and a literature review， tuber weight， width， length， and aspect ratio were selected as quantitative indicators of appearance， and they were measured by an electronic balance and a digital vernier caliper. Key active components， including gastrodin， p-hydroxybenzyl alcohol， parishins， and total polysaccharides， were quantified via ultra performance liquid chromatography-tandem mass spectrometry （UPLC-MS/MS） and the phenol-sulfuric acid method. Descriptive statistics and K-means clustering analysis were employed to establish the threshold ranges for the excellent shape and high quality indicators. ResultsTwo specific quantitative evaluation systems for characterizing the excellent shape and high quality of fresh Gastrodiae Rhizoma were established. System 1： tuber weight > 83.90 g， tuber width > 3.50 cm， total gastrodin and p-hydroxybenzyl alcohol content > 0.277%， and total parishin content > 0.561%. System 2： tuber length < 9.89 cm， aspect ratio < 3.41， and total polysaccharide content > 195.274 mg·g-1. The verification results showed that the systems effectively identified fresh Gastrodiae Rhizoma samples with both excellent appearance features and stable bioactive components. ConclusionThis study establishes a multi-dimensional evaluation and grading system for fresh Gastrodiae Rhizoma based on the correlation between shape and quality. This framework provides a scientific basis for the quality control and resource grading of fresh Gastrodiae Rhizoma and lays a methodological foundation for the efficient utilization of both the medicinal and edible value of this herbal medicine.
