AI Article Synopsis

  • The study aimed to create identification standards using microscopic features for four species in the Uncaria genus.
  • The research involved examining the microscopic characteristics of both the transverse sections and powder of these rattan species.
  • Key identification features include the presence of cork cambium, pericycle, phloem fiber, and stone cells in sections, as well as scalariform vessels, calcium oxalate crystals, and stone cell quantity in powders.

Article Abstract

Objective: To establish microscopic identification standards for four species from Uncaria genus.

Methods: The microscopic characteristics of transvers section and powder of these four species rattan were observed.

Results: As for these four species from Uncaria genus, the microscopic identification of rattan transvers section could be made by the existence of cork cambium and pericycle in the cortex, and the location of phloem fiber and stone cells, while the powder identification could be made according to the existence of scalariform vessel and calcium oxalate crystal, and the quantity of stone cells.

Conclusion: The microscopic characteristics of rattan can provide information for identification of these four species from Uncaria genus.
