Genetic variation of Kaempferia (Zingiberaceae) in Thailand based on chloroplast DNA(psbA-trnH and petA-psbJ) sequences

Phylogenetic Analyses of Molecular Data and Reconstruction of Morphological Character Evolution in Asian <I>Impatiens</I> section <I>Semeiocardium</I> (Balsaminaceae)

“…The nuclear ribosomal internal transcribed spacer ("ITS" hereafter) and the plastid atpB-rbcL intergenic spacer ("atpB-rbcL" hereafter) were amplified following Yuan et al (2004) and Janssens et al (2006). The total PCR reaction volume was 50 μl and the reaction mix, modified from Techaprasan et al (2010), contained 1 × PCR buffer (Thermo Scientific, Massachusetts, U. S. A.…”

Phytochemistry and medicinal properties of Kaempferia galanga L. (Zingiberaceae) extracts

“…genetic variations are not observed in many Kaempferia species including KG, taxonomic identification of Kaempferia species is quite difficult due to the morphological similarities in the vegetative parts of Zingiberaceae (Techaprasan et al, 2010). That is why misuse of other species, for instance Kaempferia marginata as KG is quite common (Yu et al, 2000).…”

“…Ethyl-p-methoxycinnamate isolated from extracts of KG has considerable activity against Mycobactrium tuberculosis and Candida albicans (Kanjanapothi et al, 2004, Techaprasan et al, 2010. More recently, this ethyl-p-methoxycinnamate by resazurin microtitre assay has shown to inhibit drug susceptible and multidrug resistant clinical isolates of M. tuberculosis with minimum inhibitory concentration (MIC) of 0.242 to 0.485 mM (Lakshmanan et al, 2011).…”

“…The plant is native to tropical Asia including southern China, Indochina, Thailand, Taiwan, Malaysia and India (Koh, 2009;Mitra et al, 2007;Techaprasan et al, 2010). Being a source of valuable bioactive compounds, KG is famous for its medicinal as well as edible use (Techaprasan et al, 2010). Although included in the list of 112 medicinal herbs and spices issued by the international organization for standardization, KG is one of those medicinal herbs which are still comparatively less known and are underutilized (Peter, 2004).…”
