Pharmacognostic Specification of Naringi crenulata Stem Wood

Abstract

Pharmacognostic specification of Naringi crenulata stem wood, a traditional cosmetics in Southeast Asia, was done by studying on twelve wood samples from different sources. The powdered stem wood had a sweet natural fragrance but tasteless. Stem wood fibers were predominately found with large amount of longitudinal cells in addition to high lignin content in cell wall. Wood parenchyma contained starch granules and calcium oxalate crystals with oil globules thoroughly distributed. Alkaloids and coumarin tests were positive. Moisture content and loss on drying were 6.125% ± 0.653 and 7.564% ± 1.146, respectively. Total and acid insoluble ash contents were 1.198% ± 0.515 and 0.035% ± 0.077, respectively. Extractive values of 95% EtOH, EtOAc and H2O were 0.165% ± 0.058, 0.036% ± 0.008 and 0.533% ± 0.117, respectively. HPLC chromatograms of twelve wood samples were similar in patterns but diverse in quantity. Arbutin content was 0.750% ± 0.414 of the crude extract weight.
