Telah dilakukan penelitian mengenai uji toksisitas ekstrak dari daun nanas kerang (Tradescantia spathaceae Sw.) dengan metode Brine Shrimp Lethality Test (BSLT). Penelitian ini bertujuan untuk mengetahui adanya aktivitas toksik dari ekstrak dan mengetahui pengaruh metode ekstraksi terhadap uji toksisitas pada daun nanas kerang. Ekstraksi daun nanas kerang dilakukan dengan metode maserasi dan Refluks. Uji toksisitas dilakukan terhadap larva udang Artemia salina L. Hasil dari penelitian pada metode Refluks memiliki aktivitas toksik yang cukup tinggi pada konsentrasi 132,236 ppm dibandingkan dengan ekstrak maserasi pada konsentrasi 193,001 ppm. Hasil Kromatografi Lapis Tipis (KLT) menunjukkan bahwa pada ekstrak etanol dan fraksi etil asetat diduga terdapat senyawa triterpenoid.

Has done research on toxicity test of extract from leaves of pineapple shells (Tradescantia spathaceae SW.) method with Brine Shrimp Lethality Test (BSLT). This research aims to know the existence of the toxic activity of extracts and find out the influence of extraction methods against toxicity test on the leaves of pineapple shells. Extraction leaves pineapple shells carried out with methods of maceration and Reflux. Toxicity test of Larval Shrimp Artemia salina l. Results of the research on the methods of Reflux have high enough toxic activity on the concentration of 132.236 ppm compared to extract maceration on the concentration of 193.001 ppm. Thin Layer Chromatography results (TLC) showed that the extract on ethanol and ethyl acetate fraction allegedly contained compounds triterpenoid.

We report the toxicity tests of the leaf extract of pineapple shells (Tradescantia spathaceae Sw.) By the method of Brine Shrimp Lethality Test (BSLT). This study aims to investigate the toxic activity of the extract and determine the effect of the extraction methods of toxicity tests on the leaves of pineapple shells. Extraction of pineapple leaves mussels done by maceration method and reflux. Toxicity tests conducted on shrimp larvae Artemia salina L. Results of the research on methods reflux has toxic activity at concentrations high enough 132.236 ppm compared with maceration extract at a concentration of 193.001 ppm. The results Thin Layer Chromatography (TLC) showed that the ethanol extract and ethyl acetate fraction are suspected triterpenoid compounds.
