Research

Three species of ''Kaempferia'', i.e., ''K. galanga, K. rotunda'', and ''K. angustifolia'', are well studied for their essential oils along with other important phytochemical and medicinal properties. The micropropagation procedures of ''K. galanga'' and ''K. rotunda'' have been studied by many groups for more than two decades, but ''in vitro'' propagation of ''Kaempferia angustifolia'' was the first reported in 2018.Haque SM, Ghosh B. (2018) Micropropagation of ''Kaempferia angustifolia'' Roscoe - An Aromatic, Essential Oil Yielding, Underutilized Medicinal Plant of Zingiberaceae Family. J. Crop Sci. Biotech. 21 (2):147-153. https://doi.org/10.1007/s12892-017-0051-0
