Crude Methanol Extract

The crude methanol extract of leaves, seeds and stem-bark of Clitoria ternatea demonstrated a significant cytotoxic activity in a brine shrimp lethality bioassay test. The LC50 values of the crude methanol extract of leaves, seeds and stem-bark were found to be 25.82, 110.92, 179.89 μgm/ml respectively Among them crude methanol extract of leaves (25.82 μgm/ml) and methanol fraction of leaves (22.28 μgm/ml) showed a very promising cytotoxic activity. Further studies have been suggested to discover a novel bioactive compound from methanol fraction of leaves of Clitoria ternatea.   DOI: 10.3329/bjpp.v22i1.3564Bangladesh J Physiol Pharmacol 2006; 22(1/2) : 18-21

ABSTRACTBioactive compounds that are suspected of having anticancer activity are first tested for activity by means of a toxicity test. The purpose of this test is to obtain data on the ability of the activity of a bioactive compound to kill cells at small doses so as to obtain a lethal concentration or lethal data. These two measurements are often called LC50 or LD50, concentrations that can kill 50% of test animals. This study aims to test the cytotoxic activity of Thalassia hemprichii seagrass extract using the Brine Shrimp Lethality Test (BSLT) method.The results of the study showed that the mortality of Artemia salina larvae was influenced by the concentration of the test, meaning that the higher the concentration the more test animals died. Furthermore, the results of the probit analysis contained the toxicity activity of bio active compounds from seagrasses where the LC50 was 3.95 mg / l. A substance is declared to have the potential for cytotoxic activity if it has a value of LC50 at concentrations <1000 ppm for extracts and at concentrations <30 ppm for a compound. Keywords: Cytotoxic Activity, Thalassia hemprichii, Brine shrimp Lethality Test (BSLT)

Stem Extract

The antioxidant, antibacterial and cytotoxic properties of methanol extract of Urtica crenulata (syn: Laportea crenulata Gaud) stem has been investigated in the present study. The antioxidant and cytotoxic activity of the Urtica crenulata methanol extract were assessed by DPPH free radical scavenging method and brine shrimp lethality bioassay method, respectively. The antibacterial activity of the plant extract (500 μg/disc) was also carried out by disc diffusion technique. Stem extract showed DPPH (2,2-diphenyl-1-picrylhydrazyl) free radical scavenging effect compared with ascorbic acid. IC50 value of ascorbic acid and stem extract was found 14.72 μg/ml and 1468.9 μg/ml, respectively. In antibacterial experiment, Urtica crenulata stem extract showed 8, 14 and 10 mm of diameter of zone inhibition against Salmonella typhi, Shigella flexneri and Shigella sonnei, respectively and 9 and 8 mm of diameter of zone inhibition against Bacillus subtilis and Bacillus cereus but no activity was observed against Staphylococcus aureus. In brine shrimp lethality assay, the LC50 value of the extract was found 104.0 μg/ml, which indicates that the extract has high cytoxic effect. The present study demonstrates that methanol extract of Urtica crenulata stem has significant cytotoxic effect. The extract also showed some moderate antibacterial and minimum significant antioxidant effects.  Keywords: Urtica crenulata;  Antioxidant; Antibacterial; Cytotoxic; BHT. © 2010 JSR Publications.

Abstract Background Spondias mombin Linn. is a tropical climate plant with wide applications in ethnomedicinal practice. This study evaluates the phytotoxicity, cytotoxicity and chemical composition of the plant’s stem bark. Methods Dried stem bark sample of Spondias mombin Linn. was subjected to exhaustive extraction and partitioned into sub-fractions (hexane-ethylacetate, ethylacetate, ethylacetate-methanol and methanol) by graded polarity technique. The phytotoxicity and cytotoxicity indices of the crude hydro-ethanol extract and fractions were evaluated using Lemna minor and brine shrimp lethality assays, respectively, while chemical composition of the oily hexane:ethylacetate fraction was determined by gas chromatography-mass spectroscopy (GC-MS) technique. Results Phytotoxicity was dose-dependent which ranged from low (crude plant extract), moderate (hexane-ethylacetate and methanol fractions), high (ethylaacetate-methanol fraction) to significant toxicity (ethylacetate fraction) at the highest dose. However, for brine shrimp lethality assay only hexane-ethylacetate (LD50: 284.02 μg/mL) and ethylacetate (LD50: 210.24 μg/mL) fractions were cytotoxic at the highest dose. The GC-MS profile of the oily hexane:ethylacetate fraction identified sixty-eight compounds comprising hydrocarbons, fatty acids, alcohols, steroids, nitrogen and fluoride-containing compounds, terpenes and esters. Conclusion This study concludes that fractions of Spondias mombin Lin. could be potentially toxic. While its phytotoxic potential can be useful in the agrochemical industry for the production of natural herbicides, its cytotoxic property can be cautiously harnessed for ethnomedicinal purposes.

Solvent partitioning followed by column chromatography of the MeOH extract of the seeds of Swietenia mahagoni afforded two limonoids, swietenolide (compound 1) and 2-hydroxy-3-O-tigloylswietenolide (compound 2), later one is new compound. The compounds were identified by spectroscopic means. The cytotoxic activity of these compounds was assessed by using the conventional brine shrimp lethality bioassay. While both compounds were found to have moderate cytotoxic activity, compound 2 displayed overall more potent activity than compound 1.
