Evaluation of chemical similarity among rhizome, pseudo stem and leaf of Musa basjoo by UPLC-ELSD fingerprint combined with chemo metrics methods.

ABSTRACT

Rhizoma Musa (the Rhizome of Musa basjoo Sied.et Zucc.) is used as a traditional medical herb of Miao nationality in Guizhou province, in China. It has the efficacy of clearing heat and detoxifying, quenching thirst, diuresis, etc. Modern pharmacological studies have shown that it has hypoglycemic, inhibition of α-glucosidase, and anti-inflammatory activity. However, when the rhizomes of Musa basjoo are dug up, the rhizomes are unable regenerate, and the pseudostem and leaf are discarded, which not only pollutes the environment, but also causes a huge waste of herb resources. In this study, a UPLC-ELSD fingerprint analysis with chemometric method was applied for the evaluation of chemical similarity among rhizome, pseudostem and leaf of Musa Basjoo. The results indicated that the combined method could efficiently analyze and compare the chemical similarity among rhizome, pseudostem, and leaf of Musa Basjoo. The proposed method provides the foundation for the resource substitution of the rhizome, pseudostem, and leaf of Musa Basjoo.
