Cytogenetics Study of Medicinal plants of Genus Alpinia two Rare Species from Thailand

Abstract

250 species, is the largest genus in the Alpinieae tribe, Alpinoideae subfamily, and Zingiberaceae family. Alpinia was found in tropical Asia, Australia, the Solomon Islands, the New Hebrides, New Caledonia, Fiji, and Samoa, as well as other Pacific island nations. 1,4,5 There are over 160 species in the genus, most of which are found in the Malesian region. Larsen examined the genus Alpinia in Thailand in 1996 with 13 species, Saensouk et al. followed in 2003 with 14 species, and Chumroenphat and Saensouk in 2022 with 15 species. 6,7 Furthermore, according to research by Ragsasilp et al. in 2022 and Chumroenphat and Saensouk in 2022, the genus Alpinia species were traditionally used as medicinal, food, ornamental, cosmetics, and ritual plants. In particular, A. macrostaminodia Chaveer, Sudmoon, and A. latilabris Ridl were used as local medicinal and food plants. 3,5,8 While the conservation status of Alpinia species was determined to be A. macrostaminodia Chaveer and Sudmoon (rare and endemic species) and A. latilabris Ridl (Least Concern, or LC, and rare species) based on many databases and the literature that was available. 5,9,10,11
