Abstract:Objective: To study the Physalis Calyx Seu Fructus microscopic characteristics and formulate standard of microscopic identification. Method: The calyx, peduncle, peel, seed of Physalis Calyx Seu Fructus production by FAA fixed, fixed liquid paraffin wax production method; The Physalis Calyx Seu Fructus powder production method of chloral hydrate through, dilute glycerin sealing method. The main structure and microscopic characteristics of powder were observed and taken pictures by the OLYMPUS DP72 optical microscopy. Result: The Physalis Calyx Seu Fructus materials of every part tissue section of no less than five tickets, for 10 batches of Physalis Calyx Seu Fructus powder microscopic characteristics of samples was observed, the characteristics of clear, conform to the requirements of the microscopic identification. Conclusion: Provide a reference for the standard of the Physalis Calyx Seu Fructus microscopic identification.
