白及Bletillae Rhizoma为兰科多年生植物白及的干燥块茎,具有较高的药用价值。为了满足市场的需求,我国许多省份加大了对白及的人工种植,而人工种植白及的品质是我国白及产业高质量发展的基本保障。白及的品质主要由白及多糖、白及苷、总酚等有效成分决定。通过对白及块茎中白及多糖、白及苷、总酚在不同省份、种植年限、年龄的分布特征进行综述,讨论白及块茎中主要有效成分的影响因素。并探讨白及地上部分和须根的药用潜力,及对白及地上部分、块茎、须根下一步在品质、种植方面的研究内容进行展望,为白及地上部分、块茎、须根的资源合理开发利用提供参考依据。

Baiji (Bletillae Rhizoma) is the dried tuber of Bletillla striata, a perennial plant in the Orchidaceae family, has great medicinal potential. In order to meet market demand, the artificial cultivation of Bletillae Rhizoma has been increasing in many province and regions of China, the quality of the artificially planted Bletillae Rhizoma is the basic guarantee for the high-quality development of China's Bletillae Rhizoma industry. The quality of Bletillae Rhizoma is mainly determined by effective ingredients such as Bletillae Rhizoma polysaccharide, militarine, and total phenol. By reviewing the distribution characteristics of these components in Bletillae Rhizoma tuber from different provinces, planting years, and ages to discuss the factors that influence the main effective ingredients. Additionally, the medicinal potential of Bletillae Rhizoma's above-ground parts and roots was discussed, and future research on the quality, and cultivation of Bletillae Rhizoma above-ground parts, tuber, and roots was proposed to provide a reference for the wise development and utilization of these resources.
