Abstract

            Taxonomic studies of Terrestrial Aroids (Araceae) in Saiyok national park, Kanchanaburi province were carried out during January-December 2012 by using classical taxonomy. It was found eight genera and thieteen species of Terrestrial Aroids (Araceae) were identified, namely Aglaonema simplex (Blume) Blume, Alocasia acuminata Schott, Alocasia hypnosa J. T. Yin,Y. H. Wang & Z. F. Yu, Amorphophallus cruddasianus Prain ex Engl., Amorphophallus maxwellii Hett.,  Amorphophallus muelleri Blume, Amorphophallus paeoniifolius (Dennst.) Nicolson, Arisaema maxwellii Hett. & Gusman, Colocasia esculenta (L.) Schott, Colocasia gigantea (Blume) Hook. f., Lasia spinosa (L.) Thwaites, Sauromatum horsfieldii Miq. and Typhonium trilobatum (L.) Schott. Secondary metabolites were extracted from modified stems of 11 terrestrial aroids species (except  Amorphophallus cruddasianus Prain ex Engl. and Sauromatum horsfieldii Miq.) Thin Layer Chromatography (TLC) screening and detection using different specific reagents showed terpenoids, phenolic compounds, courmarin, and alkaloids. The TLC profiles of terpenoids at Rf 0.30, 0.40, 0.91 were similar to phenolic compounds at Rf 0.20, 0.33, 0.95. Courmarin and alkaloids were found specific in 7 species. For  this case study, lipophilic extract from Lasia spinosa Thwaites rhizome effected on seed germination and seedling growth of invasive plant, Mimosa diplotricha C. Wright ex Sauvalle, the results showed that lipophilic extract could delay seed germination in culture dish and effected to seedling characteristics after transplanting 1 week.
