Abstract

One of the plants used by the people of East Kalimantan, especially the people of West Kutai, as a medicinal plant is Kitolod (Hippobroma longiflora L.). The plant parts used are the leaves and flowers. The secondary metabolites contained in Kitolod leaves are alkaloids, saponins, flavonoids and polyphenols. The aim of this research is to identify secondary metabolite groups and test the cytotoxicity of Kitolod leaf extracts and fractions. Secondary metabolites are identified qualitatively using various chemical reagents and metabolites characterized by the presence or absence of color changes or the presence of sediment or foam. Cytotoxicity testing was carried out using the Brine Shrimp Lethality Test (BSLT) method. The data research was analyzed using the Reed and Muench method to determine the Lethality Concentration 50% value. The results of research on the metabolite content of ethanol extract, fractions: n-hexane, ethyl acetate and n-butanol contain alkaloid, flavonoids and phenolic/polyphenols compounds. The bioactivity test results for the ethanol extract had an LC50 value of 592.93 ppm, the n-hexane fractions of 582.77 ppm, the ethyl acetate fraction of 531.37 ppm, and the n-butanol fraction of 119.48 ppm. These results indicate that the n-butanol fraction of Kitolod leaves has stronger cytotoxic activity than other extracts. .

Abstract

A study was conducted on the secondary metabolite content and toxicity testing of Artemia salina leach larvae using extracts from Bangkal leaves (Nauclea subdita (Korth.) Steud.) and Genjer plants (Limnocharis flava (L.) Buch). The objective of this study is twofold: firstly, to ascertain the compounds present in Bangkal leaf extract and Genjer plant extract, and secondly, to assess the toxicity levels of the extracts and fractions from Bangkal leaves and Genjer plants on Artemia salina Leach larvae. In this study, the extraction method employed was maceration with 96% ethanol as the solvent. The crude 96% ethanol extract was fractionated in stages using n-hexane, ethyl acetate, and n-butanol solvents based on polarity levels. The toxicity testing was conducted using the Brine Shrimp Lethality Test (BSLT) method, with Artemia salina Leach larvae serving as the bioindicator. A range of test concentrations were utilised, with each concentration having three replicates. The mortality of Artemia salina was observed after a 24-hour period and was analysed using the Reed and Muench method to determine the LC50 value. The results of the study demonstrated that the secondary metabolites present in the 96% ethanol extract of bangkal leaves com-prised the following groups of compounds: steroids, and triterpenoids, phenols, quinones, and saponins. The toxicity test results of the bangkal leaf extract and fractions yielded LC50 values of 418.79 ppm for the 96% ethanol extract; 716.14 ppm for the n-hexane fraction; 263.03 ppm for the ethyl acetate fraction; and 70,79 ppm for the extract n-buthanol fraction. Meanwhile, the toxicity test results of the genjer plant extract and fractions obtained an LC50 value of 490.23 ppm for the 96% ethanol extract; n-hexane fraction 551.31 ppm; ethyl acetate fraction 425.01 ppm; and n-butanol fraction extract 46.02 ppm. These results indicate that the n-butanol fraction of bangkal leaves and genjer plants have stronger cytotoxic activity than other fraction extracts.
