Abstract:
To prepare Cinnamomi Ramulus pieces standard decoction and establish its quality standard, provide quality reference for formula granules and other clinic non-traditional forms of medicines, and lay a foundation for standard decoction research for the pieces containing essential oil. 14 batches of Cinnamomi Ramulus pieces with different quality were collected from market and their extraction process was further improved based on the preparation principle of standard decoction to prepare the standard decoction of Cinnamomi Ramulus pieces. Then its transfer rate of Cinnamaldehyde, dry extract rate and pH value were calculated to evaluate its process stability; and a method for chromatographic fingerprint and content determination was also established. Results revealed that the dry extract rate for standard decoction of Cinnamomi Ramulus pieces was from 6.06%-8.95%, with an average value of 7.18%; the transfer rate of cinnamaldehyde was at the range of 29.6%-54.3%, with an average of 43.2%; and the pH value was at the range of 4.33-4.82. The fingerprint similarities between 14 batches of standard decoction of Cinnmomi Rammulus pieces and reference fingerprint were all>0.9. The established method for standard decoction was stable and its quality standard was perfect, suitable for evaluating the quality of standard decoction of Cinnanomi Ramulus pieces.
