Study of medicinal properties of Arisaematis Rhizoma Preparatum and Arisaema Cum Bile based on delayed luminescence of Scenedesmus sp / 中草药

ABSTRACT

Objective To find delayed luminescence parameters that could characterize the cold and hot properties of Arisaematis Rhizoma Preparatum and Arisaema Cum Bile. Methods Delayed luminescence of Arisaematis Rhizoma Preparatum with addition of Scenedesmus sp. within 26 d after decoction was measured in unequal interval, with aim to verify the stability of the natural delayed luminescence average strength and the linear fitting slope value (k) of excitation delayed luminescence. The delayed luminescence of six batches of Arisaematis Rhizoma Preparatum and Arisaema Cum Bile was measured using biological indicator method, and the content of β-sitosterol in Arisaematis Rhizoma Preparatum and β-sitosterol, bilirubin, and cholic acid of Arisaema Cum Bile was determined using high performance liquid chromatograph (HPLC) to analyze the correlation of k value and the above components content of Arisaematis Rhizoma Preparatum and Arisaema Cum Bile. Results K value of excitation delayed luminescence within 14 d after decoction was steadier than natural delayed luminescence average strength, and k values of six batches of Arisaematis Rhizoma Preparatum were all higher than that of Arisaema Cum Bile. A significant negative correlation between β-sitosterol contents and k values of six batches of Arisaematis Rhizoma Preparatum and Arisaema Cum Bile was found, and no significant negative correlation between bilirubin and cholic acid contents and k values of Arisaema Cum Bile was found. Conclusion K value of excitation delayed luminescence could indicate the differences of medicinal properties of Arisaematis Rhizoma Preparatum and Arisaema Cum Bile, which provides a new method for the study of medicinal properties of Chinese materia medica.
