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.

Abstract

This research aimed to identify steroid compound from leaf of gayam (Inocarpus fagiferus Fosb) and test its antioxidant activity. Dried leaf powder of gayam was extracted with 5000 mL of 96% ethanol to yield 28,05 g concentrated extract. This extract was then fractionated into n-hexane and choloform to yield 14,18 g n-hexane and 2,21 g choloform fractions respectively. The test using Lieberman Burchard reagent showed that both fractions contain steroid, but n-hexane fraction contained more steroid than chloroform fraction. Separation of n-hexane fraction was done using silica gel column chromatography with n-hexane : ethanol (7:3) as eluent and four groups of fraction were obtained. Fraction F1 contained steroid and was relatively pure therefore it was then identified. The infrared and ultraviolet-visible spectra suggest that the isolate (F1 fraction) has functional groups such as O-H, C=O, C-H, and unconjugated C=C and showed lmax at 279,407, and 669 nm. The antioxidant test showed that the isolate had antioxidant activity toward DPPH with IC50 of 4 ppm.

This study aimed to isolate and identify cytotoxic compounds of nagasari leaves by extracting 1000 g of leaf powder with 10 L of 96% ethanol  (5L x 2) to produce 66.81 g of ethanol extract (LC50 = 19.06 ppm). Fractionation of the ethanol-water extract (7: 3) in a row with 300 mL of n-hexane, chloroform 400 mL, 400 mL of n-butanol, and water and toxicity tests against larvae of Artemia salina Leach generate 2.52 g of n-hexane extracts (LC50 = 275.42 ppm), 7.06 g chloroform extract (LC50 = 63.10 ppm), 9.54 g of n-butanol extract (LC50 = 27.54 ppm) and 25.38 g aqueous extract (LC50 = 478 , 63 ppm). N-buthanol extract which was the most toxic was then separated, purified and identified. The separation of 2.0 g of n-butanol extract using column chromatography techniques with silica gel 60 as the stationary phase and chloroform- n-butanol (5: 3) as the mobile phase resulted in 5 fractions (F1, F2, F3, F4, and F5). Fraction F1 which was the most toxic (LC50 = 91.20 ppm) was then separated by preparative Thin Layer Chromatography and resulted two fractions (FA and FB). Fraction FB was the most toxic with LC50 = 83.18 ppm. UV-Vis and IR spectrophotometric analysis of FB identified a compound suspected to be terpenoides that has the characteristics of functional groups such as O-H, O = C-OH, aliphatic C-H.

Abstract

Isolation and identification of toxic compounds from ethanol extract of Prunus domestica L. have been conducted. Extraction of 1000 gr of plum fruit produced 128,75 g concentrated ethanol extract. The results of toxitcity tests of the extract using Artemia salina L. larvae showed the LC50 value of 100 ppm. Partition of ethanol extract yielded chloroform (10,52 g), n-hexane (26,58 g), and water (52,57 g) extracts. The toxicity test showed the chloroform extract to be the most toxic with LC50 of 31,97 ppm. Chloroform extract was separated by column chromatography using silica gel as stationary phase and chloroform : ethanol : water (5:4:1) as mobile phase giving three fractions. The toxicity test showed that fraction II was the most toxic with LC50 of 364,74 ppm. The phytochemical test result showed  that fraction II (the active isolate) belonged to terpene groups. Analysis using UV-Vis spectrophotometer showed three peaks at 241,  409, and 668 nm, showing the possibility of the presence of funtional groups of C-H aliphatic, C-O alkoholic and C=O, respectively
