Analysis on Physiochemical Indexes of Four Kinds of Rhizome Chinese Medicinal Herbs Stored in Simple and Cool Warehouses
Objective: To explore the change rules of color and chemical components of four kinds of rhizome Chinese medicinal herbs[Polygoni Multiflori Radix(PMR)
Angelicae Dahuricae Radix(ADR)
Notoginseng Radix et Rhizom
powder of Notoginseng Radix et Rhizoma] under two kinds of storage conditions. Method: These Chinese medicinal herbs were stored in simple warehouse and cool warehouse for 27 or 33 months. Their color was then observed under the sunlight. Their water content was determined based on the drying method. The contents of chemical components were determined by high performance liquid chromatography (HPLC) method. Result: With the increase of storage time
the color was deepened gradually and the content of 5-hydroxymethylfurfural (5-HMF) was increased in a wavy way for PMR stored in simple warehouse and cool warehouse. The content of stilbene glycoside was decreased and the content of combined anthraquinones was increased in a wavy way for PMR stored in simple warehouse. The content of stilbene glycoside was increased in a wavy way and the content of combined anthraquinones had no significant change for PMR stored in cool warehouse. The color deepened gradually and the content of imperatorin had no significant change for ADR stored in both simple warehouse and cool warehouse. The contents of ginsenosides Rg1 and Rb1 and notoginsenoside R1 as well as the color of Notoginseng Radix et R hizoma (NRR) and powder of Notoginseng Radix et Rhizoma showed no significant changes. Conclusion: The color and the contents of chemical components in PMR after 33 months and ADR
NRR and powder of NRR after 27 months storage in both simple warehouse and cool warehouse were changed slightly
but the quality of these four rhizome Chinese medicinal herbs were still controlled within the standard range.
