Objective To quantitatively analysis and comprehensively evaluate the active component content and nutritional value of hybrid Gastrodia elata and its parent varieties. Methods A combination of ultra performance liquid chromatography, automatic amino acid analyzer and Dumas nitrogen analyzer was employed to conduct a quantitative analysis and comprehensive evaluation of their active component contents and nutritional values. One-way analysis of variance was performed using SPSS. Results The hybrid Gastrodia elata exhibited significant advantages in active component content. For instance, the total content of gastrodin and p-hydroxybenzyl alcohol in WH03 reached 1.082%, with a parishin content of 0.750%, both significantly higher than those of the parent varieties. In terms of nutritional value, the total amino acid content and protein content of hybrid Gastrodia elata were also superior to those of the parent plants. Specifically, the hybrid Gastrodia elata WH03 exhibited a total amino acid content of 7.604% and a protein content of 10.12%. Conclusion This study establishes a chemometrics-based comprehensive evaluation model for Gastrodia elata quality, revealing the chemical quality improvement patterns of hybrid strains, and provides critical scientific evidence for the genetic improvement and industrial development of Gastrodia elata.
