Abstract

Garcinia tetranda Pierre (Clusiaceae) is a plant that is widely used to treat various diseases and its chemical compounds has not been much studied. Compound isolation using the three methods of chromatography (Vacuum Liquid Chromatography Column (VLCC), preparative Thin Layer Chromatography (pTLC) and TLC) generate novel compound 5,7,4 ', 5'', 7'', 3''', 4 '''-heptahidroksi-2'''-methoxy-flavanon [ 3,8 ]-flavone'' which is different from the compounds that had been found previously in Garcinia tetranda Pierre. Structure identification was conducted using UV, IR and NMR spectroscopic data and by comparing the 13C and 1H-NMR data of the isolate compound and known biflavonoid compounds. Biogenesis pathway analysis of the new compound showing relationship with molecular compounds which have previously been found in Garcinia. Antibacterial test of the novel compound using Kirby-Bauer agar diffusion methode against Gram-negative bacteria Salmonella typhi showed that the compound is not potentially used as antibacterial agent compared to chloramphenicol.

Abstract

ABSTRACT Development stage of parasite resistance assay and the Globin accumulation using SDS-PAGE Method has been done to parasite P. falciparum by giving α-mangostin from G. tetranda. α-Mangostin cause delays in the development stage of the parasite P. falciparum from stage schizont to stage trofozoit and cause parasite death after 48 hour. Swelling of the parasite of abnormal parasite food vacuole occurred after administration of α-Mangostin show from the results of SDS-PAGE. Key word : α- Mangostin, G. tetranda, P. falciparum, globin accumulation ABSTRAK Telah dilakukan pengujian hambatan perkembangan stadium parasit dan akumulasi globin menggunakan metode SDS- PAGE terhadap P. falciparum dengan pemberian α-Mangostin dari G. tetranda. Diketahui α-Mangostin menyebabkan penundaan perkembangan parasit P. falciparum dari stadium trofozoit menjadi stadium skizon dan menyebabkan parasit mati setelah jam ke 48. Pembengkakan vakuola makanan parasit yang abnormal terjadi setelah pemberian α- Mangostin terlihat dari hasil SDS-PAGE. Kata Kunci : α-Mangostin, G. tetranda, P. falciparum, , akumulasi globin
