Objective:

2

To explore the feasibility of Photoshop image processing software in the micro-spherical diameter measurement and identification of medicinal materials

in order to provide a new method for the measurement and mapping of traditional Chinese medicine.

Method:

2

Photoshop (CS3 version and above) software was used to measure the diameter of 200 Notoginseng Radix et Rhizoma albumin microspheres in the same batch

digital microscopy and Photoshop image processing software was used to draw schematic diagrams of microstructures of Notoginseng Radix et Rhizoma medicinal powders and its four common pseudo-products and powders

namely Bletillae Radix

Alpiniae Officinarum Rhizoma

Curcumae Longae Rhizoma and

Manihot esculenta

and make the identification table for classification and identification.

Result:

2

The average diameter of the microspheres was (30.62±4.21)μm

and the diameter was mainly distributed in 20-40 μm. The average diameter of the microspheres was verified by laser particle size analyzer (30.18±4.67)μm. The differences between the two methods were not statistically significant. There were many starch granules in Notoginseng Radix et Rhizoma powder

with no calcium oxalate needle

oil cell

brown pigment and stone cell. Microscopic identification could be made for Notoginseng Radix et Rhizoma powder and 4 common counterfeits.

Conclusion:

2

Photoshop image processing software measures the diameter of the microspheres with a high speed

high accuracy

simplicity

and low requirements for measuring instruments. It provides a new way to quickly measure the diameter of microspheres. Photoshop image processing software draws a schematic diagram of the microstructure

which is convenient and faster. The original morphology of the ground-reactive microstructure provides a new method for the microstructural drawing.
