Indigenous trade of medicinal plants in South Africa is a multi-million-rand industry and is still highly relevant in terms of primary health care. The purpose of this study was to identify today’s most traded medicinal barks, traditionally and contemporaneously used for dermatological, gastrointestinal, and respiratory tract infections; then, to investigate the antimicrobial activity and toxicity of the respective extracts and interpret outcomes in light of pharmacokinetics. Thirty-one popularly traded medicinal barks were purchased from the Faraday and Kwa Mai-Mai markets in Johannesburg, South Africa. Information on the medicinal uses of bark-based medicines in modern commerce was recorded from randomly selected traders. The minimum inhibitory concentration (MIC) method was used for antimicrobial screening, and brine shrimp lethality was used to determine toxicity. New medicinal uses were recorded for 14 bark species. Plants demonstrating some broad-spectrum activities against tested bacteria include Elaeodendron transvaalense, Erythrina lysistemon, Garcinia livingstonei, Pterocelastrus rostratus, Rapanea melanophloeos, Schotia brachypetala, Sclerocarya birrea, and Ziziphus mucronata. The lowest MIC value of 0.004 mg/mL was observed against Staphylococcus epidermidis for a dichloromethane bark extract of E. lysistemon. The tested medicinal barks were shown to be non-toxic against the Artemia nauplii (brine shrimp) bioassay, except for a methanol extract from Trichilia emetica (69.52% mortality). Bacterial inhibition of bark extracts with minimal associated toxicity is consistent with the safety and valuable use of medicinal barks for local muthi market customers. Antimicrobial outcomes against skin and gastrointestinal pathogens are feasible because mere contact-inhibition is required in vivo; however, MIC values against respiratory pathogens require further explaining from a pharmacokinetics or pharmacodynamics perspective, particularly for ingested rather than smoked therapies.

Ganoderma lucidum is polyporus fungi from Basidiomycetes which can be used as traditional medicines. Toxicity test with Brine Shrimp Lethality Test (BST) method using Artemia salina was conducted to find out toxic effect of G.lucidum. An extract would have toxic effect if the LC50 < 1000 µg/ml. The aims of this experiment were to know about the toxicity level from G.lucidum with Brine Shrimp Lethality Test (BST) method and determined the concentration of fruiting body extract of G.lucidum which had the best toxicity effect in LC50. There were two extraction methods used in this experiment, first one stage extraction and then multilevel extraction with hexane, ethyl acetate, and ethanol. Each solvent was made in 1000 ppm, 500 ppm, 250 ppm, and 125 ppm. This process was repeated for three times. This experiment used G.lucidum extract which was tested to A.salina and secunder compound metabolit test from the most toxic G. lucidum was done with phytochemical analysis. The result indicated that fruiting body extract from G.lucidum could kill A.salina because all extract was positively contained alkaloid and terpenoid but negatively contained flavonoid. Fruiting body extract from G.lucidum which had lowest LC50 wass ethyl asetat extract with one stage extraction in concentration 53,70 ppm and highest LC50 was ethanol extract with multilevel extraction in concentration 501,18 ppm.

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.

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)

Brine Shrimp Lethality

Kolagen dan kitosan dapat digunakan sebagai bahan pembalut luka karena memiliki karakteristik yang baik. Namun, pembalut luka kolagen-kitosan perlu dilakukan uji sitotoksisitas sebelum diaplikasikan secara in vivo, seperti Brine Shrimp Lethally Test (BSLT). Pembalut luka kolagen-kitosan tidak dapat larut dalam Dimetil Sulfoksida (DMSO) dan aquadest dengan mudah, oleh karena itu perlu pertimbangan alternatif pelarut karena kolagen dan kitosan lebih mudah larut dalam pelarut asam seperti asam klorida (HCl) dan asam asetat ( CH3COOH). Penelitian ini bertujuan untuk mengetahui Lethal Concentration  50 (LC50) dari pembalut luka kolagen-kitosan yang dilarutkan dalam pelarut DMSO, HCl, CH3COOH dengan metode Brine Shrimp Lethality Test (BSLT). Pembalut luka kolagen-kitosan didapatkan dengan mencampurkan larutan kitosan 2% dan kolagen dengan perbandingan 1:1 w/w kemudian dihomogenkan, dicetak, dan dikeringkan.  Penelitian ini menggunakan uji sitotoksisitas dengan metode BSLT dan LC50 dihitung menggunakan Analisis Probit. Pembalut luka dilarutkan dalam pelarut DMSO 1%, CH3COOH 1%, dan HCl 1% hingga homogen, kemudian diencerkan dengan berbagai konsentrasi yaitu 100 ppm, 250 ppm, 250 ppm, 500 ppm, dan 1000 ppm dengan tiga kali ulangan untuk setiap perlakuan. Setelah itu uji BSLT dilakukan dengan menggunakan Artemia salina. Hasil penelitian menunjukkan bahwa pembalut luka yang dilarutkan dalam DMSO 1% memiliki LC50 > 1000 ppm, sedangkan pada pelarut CH3COOH dan pelarut  HCl menunjukkan  LC50< 30. Kesimpulan dari penelitian ini adalah pelarut DMSO bersifat non-toksik (LC50  > 1000 ppm), tetapi pelarut CH3COOH 1% dan HCl 1% bersifat sangat toksik (LC50 < 30 ppm) sebagai pelarut alternatif pembalut luka kolagen-kitosan pada uji BSLT.
