Discrimination of Botanical Origin of Chan-thet, Chan-hom, Chan-chamot, Chan-khao and Chan-thana Using Chemical Test and Thin-layer Chromatography
Objective: To develop the method to discriminate the botanical origin of crude drugs named Chan-thet, Chan-hom, Chan-chamot, Chan-khao and Chan-thana. Methods: Heartwoods of Santalum album, S. spicatum, S. lanceolatum, Tarenna hoaensis, Mansonia gagei, Diospyros decandra and Myristica fragrans which were likely used as above mentioned crude drugs, were examined with various chemical test reactions. Their chemical fingerprints using thin-layer chromatography (TLC) were also studied. Results: Each plant species gave different results on chemical tests and possessed unique TLC chromatograms. Conclusion: Heartwoods of all seven plant species could be discriminated by the reactions with vanillin/sulfuric acid, 10% potassium hydroxide solution and Liebermann-Burchard test. The results were confirmed by their TLC chromatograms developed from hexane-ethyl acetate-methanol (60:30:0.2) and dichloromethane-methanol-formic acid (60:10:1) as mobile phases and detected with vanillin/sulfuric acid spraying reagent. Keywords: Chan-thet, Chan-hom, Chan-chamot, Chan-khao, Chan-thana, chemical test, thin-layer chromatograph

Objective: To identify the botanical origins of âChan-Khaoâ and âChan-Thana.â Methods: Twenty-eight samples of Chan-Khao and Chan-Thanawere randomly purchased from Thai traditional drugstores. Chemicalfingerprints of their methanolic extracts were developed using thin-layerchromatography compared with authentic samples. A main chemicalcomposition was also isolated, purified and identified by spectroscopictechniques. Results: Most of Chan-Khao and Chan-Thana samplesshowed identical TLC chromatograms to Tarenna hoaensis, and containedgeniposidic acid, one of the chemical constituents found in Tarenna spp.One sample of Chan-Khao revealed a TLC chromatogram similar to that ofSantalum spicatum. Eight samples of Chan-Khao and Chan-Thana, dividedinto 3 species based on their TLC chromatograms, could not be identified.Conclusion: Nowadays commercially available Chan-Khao and Chan-Thana were originated from 5 plant species. Most of them were heartwoodof T. hoaensis.Keywords: Chan-Khao, Chan-Thana, botanical identification, Thin-layerchromatography, Tarenna hoaensi

Methods: Seventeen samples of Kot-chula-lampha wererandomly purchased from traditional drugstores. Chemical fingerprints oftheir methanolic extracts were developed using thin-layer chromatographycompared with authentic samples. Main chemical compositions were alsoisolated, purified and identified by spectroscopic techniques. Results: Mostsamples (n = 15) showed identical TLC chromatograms to Artemisiapallens, and contained cirsimaritin and davana acid, ones of the chemicalconstituents found in A. pallens. TLC chromatograms of only two sampleswere similar to A. argyi. Conclusion: Kot-chula-lampha commonly used ascrude drug nowadays was the aerial part of A. pallens.Keywords: Kot-chula-lampha, thin-layer chromatography, chemicalfingerprint, Artemisia pallens, Artemisia argyi, Artemisia vulgaris,Artemisia annu
