Abstract
The medicinal plant under the Thai name of “Thian Klaep” is still confusion now. The objectives of this study are to identify the specie and specification of crude drug under the Thai name of Thian Klaep. Method: The pharmacognostic (macroscopical character, microscopical character, chemical Identification) and physico-chemical of crude drug were studied follow the methods in Thai Herbal Pharmacopoeia to establish the specification. The 16 samples including authentic and crude drug samples were collected from different resources in various regions throughout Thailand. Results: The result showed that 2 species of crude drug under the Thai name of Thian Klaep were identified as sweet fennel (Foeniculum vulgare Mill. subsp. vulgare var. dulce) and malted barley (Hordeum vulgare L.) but most of them (13 samples) were malted barley. We didn’t find Foeniculum vulgare Mill. subsp. vulgare var. vulgare as referenced in many text books. The malted barley was selected to study for establishing the specification. The macroscopical, microscopical and chemical character of malted barley showed the typical specification. The physicochemical specifications of malted barley viz. foreign matter, loss on drying, total ash content and acid insoluble ash content were not more than 0.5, 12, 4 and 0.5 % while water, ethanol, chloroform and hexane extractive were not less than 21, 4, 3 and 2 %, respectively. Conclusion: There are 2 species; sweet fennel (Foeniculum vulgare Mill. subsp. vulgare var. dulce) and malted barley (Hordeum vulgare L.) were used under the Thai name of Thian Klaep. The specification of malted barley was established and could be used as a standard specification.
