ABSTRACT
The medicinal and edible Polygonatum cyrtonema is one of the original species of Polygonati Rhizoma. In this study,HPLC fingerprints for 25 batches of P. cyrtonema from 6 provinces were established. A total of 14 common peaks were identified and the similarities of the fingerprints were in the range of 0. 939-0. 999. In additon, the partial least squares-discriminant analysis(PLSDA) demonstrated that the samples had low discriminability except for JX-1 and most components of them had no significant correlation with environmental factors such as longitude, latitude, and altitude. Thus, chemical composition specificity of P. cyrtonema in natural distribution areas had no obvious regularity and their variation might be induced by the local environment. This conclusion explained the lack of records about Dao-di area of Polygonati Rhizoma. However, JX-1 boasted significantly higher content of 5-hydroxymethylfurfural(HMF) and 4',5,7-trihydroxy-6,8-dimethylhomoisoflavone( HIF), thick and long inflorescence and rhizome, and extremely high yield. Therefore, excellent variety of P. cyrtonema might have great potential to improve the quality and yield of Polygonati Rhizoma. Moreover, three components of HMF, polygonalline A(PA), and HIF were identified in the fingerprint. Among them, HMF has the activities of blood rheology improvement, antioxidation, and anti-myocardial ischemia and PA is an indolizine alkaloid with potential anti-inflammatory activity. HIF, the characteristic homoisoflavone in Polygonatum, has the pharmacological activities of regulating blood glucose and anti-tumor. A quantitative analysis method can provide a theoretical basis for the improvement of the quality evaluation of Polygonati Rhizoma.
