Brine Shrimp Toxicity

The present study determined the antifungal activity of the root of extracts Argemone mexicana against 7 fungi using dichloromethane and methanol as solvent. Among these pathogens, 3 were dermatophytes and the rest 4 were nondermatophytes. The dichloromethane extract of Argemone mexicana exhibited moderate to good activity at concentration of 200 ?g/disc but at concentration of 50 ?g/disc, the same extract showed no activity against the tested fungi. The methanol extract were also inactive against the tested pathogens. In brine shrimp toxicity test, it was observed that LC50 value of the dichloromethane extract of Argemone mexicana was 22.35 ?g/ml. From these findings it is indicative that dichloromethane extract of Argemone mexicana is biologically active and may have antifungal principles that could be useful in fungal diseases.KYAMC Journal Vol. 4, No.-2, Jan 2014, Page 402-405

Acacia Catechu

This study focuses on antibacterial, antioxidant and toxic potentials of Viscum album Linn, commonly known as European mistletoe associated with Acacia catechu (Khayer in Nepali). Methanol extract of the aerial parts of the Mistletoe was prepared by cold percolation method. The resulting extract was simultaneously subjected to phytochemical screening; anti-microbial activity; anti-oxidant potential and Brine shrimp toxicity test. The major biologically active phyto-constituents observed were alkaloids, glycosides, saponins, polyphenols, flavonoids, tannins, terpenoids and cardiac glycosides. Upon antibacterial activity screening, the plant extract was found to be highly effective against Pseudomonas aeruginosa with the zone of inhibition 16±1mm compared to 17±1mm of chloramphenicol (50 mcg). The antioxidant activity as EC50 value by DPPH (1,1-diphenyl-2-picrylhydrazyl) free radical scavenging activity was found to be 1.58 mg/ml while the ferric reducing capacity was measured to be 282.83±19.55 mg FeSO4.7H2O eqvt/g dry wt. of the extract during Ferric Ion Reducing Antioxidant Power (FRAP) Assay. The LC50 value for Brine Shrimp Toxicity Assay was found to be 31.62 ppm. This study shows the medicinal value of the mistletoe associated with Acacia catechu. Further meticulous analysis of this plant might lead to identification of active biomolecules effective as drugs for various ailmentsNepal Journal of Biotechnology. Dec. 2015 Vol. 3, No. 1: 60-65

Abstract : This study aims to determine the antidiabetic activity and toxicity of the acetone extract of Tristaniopsis merguensis Griff leaf. The antidiabetic test was the α-glucosidase inhibition method, while the toxicity test used the Brine Shrimp Lethality Test (BSLT) method. The acetone extract possessed antidiabetic activity with an IC50 value of 8.83 ± 0.31 (μg/mL). This value is not much different from the positive control of quercetin which has an IC50 value of 6.04 ± 0.14 (μg/mL). The characteristics of the FT-IR spectrum of acetone extract showed that Tristaniopsis merguensis leaf has the groups Ar-OH (phenolic), -OH (hydroxyl), C=O (ketone) and C=C (aromatic). Based on the toxicity test, the Tristaniopsis merguensis leaf acetone extract has an LC50 value of 959.25 ppm which means that the acetone extract is toxic. Therefore, the acetone extract of Tristaniopsis merguensis might be the potential agent of antidiabetic.Abstrak : Penelitian ini bertujuan untuk mengetahui aktivitas antidiabetes dan toksisitas dari ekstrak aseton daun Tristaniopsis merguensis Griff. Uji aktivitas antidiabetes ditentukan berdasarkan metode inhibisi enzim α-glucosidase, sedangkan toksisitas ditentukan berdasarkan metode Brine Shrimp Lethality Test (BSLT). Ekstrak aseton memiliki aktivitas antidiabetes dengan nilai IC50 8,83 ± 0,31 (μg/mL). Nilai ini tidak jauh berbeda dengan kontrol positif quersetin yang memiliki nilai IC50 6,04 ± 0,14 (μg/mL). Karakteristik spektrum FT-IR ekstrak aseton menunjukkan bahwa daun Tristaniopsis merguensis memiliki gugus fungsi Ar-OH (fenolik), -OH (hidroksil), C=O (keton) dan C=C (aromatik). Berdasarkan uji toksisitas, ekstrak aseton daun Tristaniopsis merguensis memiliki nilai LC50 sebesar 959,25 ppm yang berarti bahwa ekstrak aseton bersifat toksik. Oleh karena itu, ekstrak aseton dari Tristaniopsis merguensis berpotensi untuk dijadikan agen antidiabetes.

The bioactive compound of hyptolide has been isolated from an Indonesian plant Hyptis pectinata using various solvents. The pure compound was then used as a standard in quantitative analysis using HPLC and UV-Vis spectroscopy in ethanol (EEth), ethyl acetate (EEa), acetone (Eac) and hexane (Ehex) extract each earned 3.14%, 0.01%, 1.33% and 0.04% (dry weight per sample). The standard curve of hyptolide using UV spectroscopy has been obtained with the coefficient of relationship (r) of 0.997. However, the use of spectroscopy was not recommended for the standardization of hyptolide in the extract due to interference from other compounds that absorb the same wavelength. Furthermore, the toxicity test using the Brine Shrimp lethality test shows LC50 value of 92-181 ppm, which was in EEa compared to EEth, Eac, and Ehex.

Harmful Effects

Since 1970s, aplysiatoxins (ATXs), a class of biologically active dermatoxins, were identified from the marine mollusk Stylocheilus longicauda, whilst further research indicated that ATXs were originally metabolized by cyanobacteria. So far, there have been 45 aplysiatoxin derivatives discovered from marine cyanobacteria with various geographies. Recently, we isolated two neo-debromoaplysiatoxins, neo-debromoaplysiatoxin G (1) and neo-debromoaplysiatoxin H (2) from the cyanobacterium Lyngbya sp. collected from the South China Sea. The freeze-dried cyanobacterium was extracted with liquid–liquid extraction of organic solvents, and then was subjected to multiple chromatographies to yield neo-debromoaplysiatoxin G (1) (3.6 mg) and neo-debromoaplysiatoxin H (2) (4.3 mg). They were elucidated with spectroscopic methods. Moreover, the brine shrimp toxicity of the aplysiatoxin derivatives representing differential structural classifications indicated that the debromoaplysiatoxin was the most toxic compound (half inhibitory concentration (IC50) value = 0.34 ± 0.036 µM). While neo-aplysiatoxins (neo-ATXs) did not exhibit apparent brine shrimp toxicity, but showed potent blocking action against potassium channel Kv1.5, likewise, compounds 1 and 2 with IC50 values of 1.79 ± 0.22 µM and 1.46 ± 0.14 µM, respectively. Therefore, much of the current knowledge suggests the ATXs with different structure modifications may modulate multiple cellular signaling processes in animal systems leading to the harmful effects on public health.
