Abstract

Two alkaloid compounds (nicotine and caffeine) together with three phenolic compounds (catechin, proanthocyanidin and phenolic acid) were firstly detected in Rafflesia hasseltii and its host, Tetrastigma leucostaphylum in Bukit Tigapuluh National Park, Riau. The content of all compounds is higher in R. hasseltii than its host.© 2008 Jurusan Biologi FMIPA UNS SurakartaKey words: Rafflesia hasseltii, Tetrastigma leucostaphylum, alkaloids, phenolic compounds, HPLC.

Abstract

The detail observation had been done on the morphological characters of Rafflesia hasseltii from Bukit Tiga Puluh National Park (BTNP). Currently, this endangered and rare flower found in two populations in this park, Aek Telap and Mandi Urau, Tanah Datar. The preliminary study on morphological characters of flowers from this site shows blotches and dot pattern variability. The detail observation of morphology of R. hasseltii from BTNP, presented the similarity to its type except the blotches pattern in perigone lobe. However, the further monitoring research is still needed to observe more flowers in this site. Due to its rarity, study on all Rafflesia species must be carefully done especially in using the characters of blotch for taxonomy evidence, as this characters show the variability among the flowers within population.© 2007 Jurusan Biologi FMIPA UNS SurakartaKey words: Rafflesia hasseltii, tjendawan muka rimau, morphology
