Abstract

ABSTRAK: Telah dilakukan uji aktivitas antikanker isolat toksik dari ekstrak metanol spons genus Haliclona Grant, 1836 terhadap sel HeLa. Uji untuk mengetahui toksisitas spons genus Haliclona Grant, 1836 dilakukan dengan metode Brine Shrimp Lethality Test (BSLT) menggunakan larva Artemia salina Leach terhadap ekstrak etanol dan metanol spons tersebut. Hasil uji menunjukkan ekstrak metanol bersifat lebih toksik dengan nilai LC50 32,36 ppm. Hasil partisi ekstrak metanol menghasilkan ekstrak n-heksana, kloroform dan air. Ekstrak kloroform memiliki toksisitas paling tinggi dengan LC50 64,57 ppm. Ekstrak kloroform dipisahkan dengan kromatografi kolom silika gel menggunakan eluen etil asetat : n-heksana (2 : 8), diperoleh 5 fraksi (F1 – F5). Fraksi satu (F1) memberikan nilai toksisitas paling tinggi dengan LC50 70,79 ppm dan berdasarkan uji fitokimia diduga mengandung senyawa golongan steroid. Isolat toksik (F1) selanjutnya diuji secara in vitro terhadap sel HeLa, namun memiliki daya hambat yang sangat rendah dalam membunuh sel HeLa dengan nilai IC50 sebesar 2187,5 ppm.ABSTRACT: A research to test the anticancer activity toxic isolate of the methanol extract genus sponge of Haliclona Grant, 1836 to HeLa cells was conducted.

Abstract

The “Brine Shrimp Lethality Test” (BSLT) is a preliminary test used to monitor the bioactive compounds from natural products as anti-cancer. This research aimed to determine of toxic compounds in the leaf of waru (Hibiscus tiliaceus L.). Maceration of 900 g waru leaf powder with 7000 mL of ethanol (5x24 hours) yielded 53,19 g ethanol extract with toxicity tests to larvae of Artemia salina Leach (LC50) of 79.43. The ethanol extract was partitioned to yield 1,81 g of n-hexane (LC50 = 63,09 ppm), 1,52 g of chloroform (LC50 = 1000 ppm) and 50,08 g of aqueous extract (LC50 = 316 ppm). The most toxic, n-hexane extract, was then separated , purified and identified. n-hexane extract was separated by column chromatography with silica gel 60 as stationary phase and n-hexane-chloroform-ethanol (5:4:1) as mobile phase to yield 7 fractions. Fraction one (F1) with a single stain on thin-layer chromatography was the most toxic (LC50 = 398 ppm). Identification with phytochemical test, UV-Vis spectrophotometer and IR spectrophotometer,  showed that the isolate contained sterol compounds.
