The use of medicinal plants in traditional medicine is a common practice in developing countries. However, this unregulated or poorly rational use may present a dose-dependent risk of toxicity to humans. This study aimed to explore the phytochemical and toxicological characteristics of ten (10) plant species used in the traditional treatment of infectious diarrhea in Benin. The acute toxicity of aqueous and hydroethanolic extracts of Khaya senegalensis, Daniellia oliveri, Rauvolfia vomitoria, Vernonia amygdalina, Manihot esculenta, Ocimum gratissimum, Senna italica, Diospyros mespiliformis, Pterocarpus erinaceus, and Anacardium occidentale was evaluated following the OECD 423 protocol at a single dose of 2000 mg/kg. This safety test was complemented by a larval cytotoxicity test. Hematological and biochemical examinations, as well as a histological study of the liver and kidneys, were performed. Larval cytotoxicity was assessed by the sensitivity of Artemia salina larvae to different concentrations of the plant extracts studied. Testing for chemical compounds was performed on the basis of differential staining and precipitation reactions. The mean lethal concentration (LC50) was determined by the probit method. The qualitative phytochemical screening of the plants studied revealed the presence of catechic tannins, gallic tannins, flavonoids, anthocyanins and sterol-terpenes, alkaloids, saponosides, and reducing compounds. This composition varied according to the plants studied. Acute toxicity data indicated that there was no mortality and no structural and functional alterations of the liver and kidneys of treated animals. Larval cytotoxicity data suggest that the plants studied are not cytotoxic (LC50 ≥ 0.1 mg/mL). These observations reflect the safety of these plants and justify their use in traditional medicine in the treatment of many diseases including diarrheal diseases.

AbstrakToksisitas akut merupakan kemampuan suatu bahan kimia (obat/bahan obat) dalam menimbulkan kerusakan  pada suatu organisme dalam waktu yang relatif singkat. Tujuan penelitian ini adalah untuk mengetahui potensi ketoksikan akut dari ekstrak metanol, fraksi etil asetat dan fraksi air kulit batang ketapang laut (Terminalia catappa L.). Pengujian toksisitas akut dilakukan dengan menggunakan metode BSLT (Brine Shrimp Lethality Test) dan menggunakan analisis program untuk mengetahui nilai LC50 dari ekstrak dan fraksi. Hasil uji toksisitas akut menunjukan nilai LC50  dari ekstrak metanol, fraksi etil asetat dan fraksi air kulit batang ketapang laut (Terminalia catappa L. )  berturut-turut 247,997 ppm; 400,666 ppm dan 618,046 ppm. Hal ini menunjukan bahwa ekstrak metanol batang ketapang laut (Terminalia catappa L.) bersifat paling toksik dibandingkan fraksi etil asetat dan fraksi air.Kata kunci: Ekstrak, Fraksi, Terminalia catappa L., BSLT, Artemia salina LeachAbstractAcute toxicity is the ability of chemical (drug/drug ingredient) to cause damage to organisms in a relatively short time. The purpose of this study was to determine the potential for acute toxicity of methanol extract, ethyl acetate and water fractions of sea ketapang stem skin (Terminalia catappa L.). Acute toxicity testing was performed using the BSLT (Brine Shrimp Lethality Test) method and program analysis to determine the LC50 values of extracts and fractions. The results of the acute toxicity test showed the LC50 values of methanol extract, ethyl acetate and water fractions of the plant stem skin consecutively were 247,997 ppm; 400,666 ppm and 618,046 ppm. This shows that the methanol extract of sea ketapang stems (Terminalia catappa L.) is the most toxic compared to the ethyl acetate and the water fraction.Keywords: Extract, Fraction, Terminalia catappa L., BSLT, Artemia salina Leach

Croton argyrophylloides Muell. Arg. is widely used in Brazilian folk medicine to treat diabetes and venereal diseases. This study examined the acute toxicity and cytotoxicity of the essential oil of C. argyrophylloides(EOCA). In addition, vascular effects of the EOCA have been examined. In mice, an oral acute toxicity test revealed that EOCA could be considered as a non toxic essential oil since it showed a very high LD50 (9.84 ± 0.01 g/kg). In the brine shrimp ( Artemia salina) cytotoxic assay, the LC50 value of EOCA was 275 [165-534] μg/mL. EOCA (1-1000 μg/mL) relaxed isolated endothelium-intact aortic rings precontracted with phenylephrine with an IC50 value of 126.7 [89.8-163.7] μg/mL. In rat mesenteric bed preparations precontracted with phenylephrine, EOCA (1-300 μg/mL) also induced a reversible, vasodilator effect with an IC50 value of 46.0 [33.3-58.7] μg/mL. It is concluded that EOCA is a very interesting agent from the point of view of the possibility of therapeutic application. This is because, whilst showing a very small acute toxicity, EOCA also showed maximal efficacy as a vascular antispasmodic agent with a pharmacological potency similar to that of other Croton species essential oils.

Objective: This study aims to investigate the anti-inflammatory effect of the ethanolic extract of Callyspongia sp. using stabilization of the human red blood cell (HRBC) membrane method and its acute toxicity using brine shrimp lethality test (BSLT) method. Methods: Callyspongia sp. was macerated with 96% ethanol. Extract characterized and screened for the secondary metabolite. Anti-inflammatory activity by stabilization of the HRBC membrane method with a varied dose of 50 ppm; 100 ppm; 200 ppm; 400 ppm; 800 ppm; 1600 ppm; and 3200 ppm. Solutions observed using a photometer to describing stability and ability in preventing membranes hemolytic and statistically analyzed using SPSS. Acute toxicity carried out by the BSLT method and analyzed using Minitab®ver. 17.2.1. Results: The phytochemical screening was indicating that Callyspongia sp. contains flavonoid, alkaloid, and terpenoid. The results of the anti-inflammatory activity test showed that the percentage value of stability and hemolysis of extracts with doses of 50, 100, 200, 400, 800, 1600, and 3200 ppm were 55% and 45%, 63% and 37%, 70% and 30%, 74% and 26%, 80% and 20%, 87% and 13%, and 97% and 3%, respectively. It showed that extract of sponge Callyspongia sp. in all varied dose has activity in stabilizing the HRBC membrane thus can be potential as an anti-inflammatory. The results of acute toxicity assay showed that the value of LC50 was 1281.45 μg/ml and categorized as nontoxic to Artemia salina Leach. Conclusion: Various concentrations of Callyspongia sp. effective as an anti-inflammatory in stabilizing HRBC, and categorized as safe.

ABSTRACTAnnona muricata is a family of Annonaceae that has been known as a medicinal plant. Sirsakleaves contain alkaloids, tannins, and several other chemical contents including acetogenin.The aim of this study was to determine the acute toxicity of the infusion of Sirsak leaves onthe Artemia salina larvae by the Brine Shirmp Lethality Test (BSLT) method. This experimentalstudy used 5 treatment concentrations (10 mg/L, 50 mg/L, 100 mg/L, 500 mg/L, 1000mg/L) and 1 negative control. All treatments were repeated 3 times. The number of Artemiasalina larvae used for each concentration was 10 larvae. The number of dead larvae wascounted after 24 hours of treatment.
