Abstract

Tujuan penelitian adalah menguji toksisitas tepung pelepah aren yang diawali dengan maserasi dengan pelarut etanol kemudian difraksinasi dengan petroleum eter, etil asetat dan air. Masing-masing ekstrak dilakukan uji toksisitas dan uji fitokimia. Metode yang digunakan untuk pengujian toksisitas adalah Brine Shrimpt Lethality Test (BSLT) dengan menggunakan larva udang jenis Artemia salina Leach sebagai bioindikator dan uji fitokimia. Hasil uji toksisitas ekstrak etil asetat tepung pelepah aren adalah bersifat sangat toksik dengan nilai LC50 < 1000 ppm (7,76 ppm) yang diikuti oleh ekstrak petroleum eter 10,69 ppm kemudian ekstrak etanol 15,81 ppm dan terakhir ekstrak air 26,92 ppm. Hasil uji fitokimia tepung pelepah aren mengandung beberapa senyawa metabolit sekunder yaitu alkaloid pada ekstrak etanol, petroleum eter, etil asetat dan air, triterpenoid hanya pada ekstrak etanol, petroleum eter dan etil asetat sedangkan ekstrak air negatif. Selanjutnya tanin yang positif adalah ekstrak etanol, etil asetat dan air sedangkan petroleum eter negatif. Kesimpulan tepung pelepah aren toksik terhadap larva udang artemia salina Leach dan mengandung senyawa metabolit sekunder alkaloid, triterpenoid dan tanin The purpose of this study was to examine the toxicity of Aren’s midrib flour that was preceded by maceration with ethanol solvent then concentrated and fractionated with petroleum ether, ethyl acetate and water. Each extract was tested for toxicity and phytochemical testing. The method used for toxicity testing is the Brine Shrimpt Lethality Test (BSLT) by using artemia salina Leach shrimp larvae as bioindicators and phytochemical tests. The results of the toxicity test of the ethyl acetate extract of aren’s midrib flour are very toxic with LC50 value <1000 ppm (7.76 ppm) followed by petroleum ether extract 10.69 ppm then ethanol extract 15.81 ppm and finally water extract 26.92 ppm. The results of phytochemical tests of aren’s midrib flour contain several secondary metabolites, namely alkaloids in ethanol extract, petroleum ether, ethyl acetate and water, triterpenoids only in ethanol extract, petroleum ether and ethyl acetate while negative water extracts.

Conclusion Aren’s midrib flour is toxic to the larvae of shrimp artemia salina Leach and contains secondary metabolites of alkaloids, triterpenoids and tannins
研究的目的是测试一种棕榈棕榈粉的毒性,这种粉末从乙醇溶剂开始,然后从乙醇溶剂开始,然后从棕榈棕榈中分离出乙醇、乙酸乙和水。每一种提取物都有毒性试验和植物化学试验。用于毒理学测试的方法是BSLT虾幼虫作为生物指标和植物化学测试。糖棕榈乙基乙醇提取物的毒性检测结果为高毒性,其值为LC50 < 776 ppm (7.76 ppm),其次是石油提取物10.69 ppm,然后是15.81 ppm提取物,最后是水质提取物26.92 ppm。植物化学测试面粉含有一些化合物的棕榈叶次生代谢乙醇提取物的生物碱、石油醚醋酸纤维素乙醇和水,只在乙醇提取物triterpenoid,石油醚醋酸纤维素乙醇而负水提取物。乙醇、乙醇和水的乙醇和乙醇的乙醇是正的。结论面粉toksik对幼虫的棕榈叶虾artemia salina Leach和次生代谢,triterpenoid生物碱化合物含有单宁这个研究的目的是to examine The toxicity棕榈midrib的面粉那是preceded由maceration乙醇solvent然后深和fractionated石油醚醋酸,乙基和水。每一份说明书都参加了毒性和植物化学测试。用于毒性测试的方法是用青蒿素作致命虾试验(BSLT)。toxicity对他们的含水率的结果是对lcyl acetate extract of他们的排泄物的毒性的再现,在petroleum extract 10.69 ppm之后,乙醇extract 15.81 ppm和最后水排水量26.92 ppm之后。对,对,对,对,对,对,对,对,对,对,对。更远的地方,最好的地方是乙醇、乙醇和水在石油以太时开采。天然棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈棕榈
