Abstract: Cancer is the biggest cause of death in Indonesia. Cancer treatment efforts have been made but it could harm cancer patients. It is necessary to find another alternative from nature as an anticancer. This study aims to see the ability of endophytic actinobacterial isolates from ginger (Zingiber officinale) as an anticancer tested using the BSLT method (Brine Shrimp Lethality Test) by calculating the values of LC50 and LT50. The best value isolates from the BSLT method, then tested using phytochemical ethanol extract. The highest toxicity value was found in AJ2 isolates. LC50 and LT50 values of AJ2 isolates were 309.358 µg/ml and 11.879 hours. Phytochemical results of ethanol extract of AJ2 isolates were detected containing steroids, terpenoids, phenols, tannins, flavonoids, alkaloids, and saponins. AJ2 isolates which derived from ginger endophytic actinobacteria have potential as an anticancer because they have high toxic values that rised rapidly.Abstrak: Kanker menjadi penyebab kematian terbesar di Indonesia. Upaya pengobatan kanker sudah dilakukan namun memberikan dampak negatif bagi penderita kanker. Perlu dilakukan penemuan alternatif lain berasal dari alam sebagai antikanker. Penelitian ini bertujuan untuk melihat kemampuan isolat aktinobakteri endofit asal jahe (Zingiber officinale) sebagai antikanker. 7 isolat aktinobakteri endofit jahe diuji menggunakan metode BSLT (Brine Shrimp Lethality Test) dengan menghitung nilai LC50 dan LT50. Isolat nilai terbaik dari metode BSLT, selanjutnya diuji  menggunakan fitokimia ekstrak etanol. Nilai toksisitas tertinggi terdapat pada isolat AJ2. Nilai LC50 dan LT50 isolat AJ2 adalah 309,358 µg/ml dan 11,879 jam. Hasil fitokimia ekstrak etanol isolat AJ2 terdeteksi mengandung steroid, terpenoid, fenol, tanin, flavonoid, alkaloid dan saponin. Isolat AJ2 yang berasal dari actinobacteria endofit jahe berpotensi sebagai antikanker karena memiliki nilai toksik yang tinggi dalam waktu singkat.

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.

Acute Toxic

Soursop fruit (Annona montana Macf.) is one of the plants can be used as as traditional medicine. This plant contains terpenoid and acetogenin which can cause toxicity. The fruit has a flavor that is tasteless so the innovation becomes probiotic drinks. This drink has been proven as an antioxidant, antibacterial, antihyperuricemia and antidiarrheal. The aim of this study was to know about acute toxicity of probiotic drink of soursop juice using brine shrimp lethality test method which will be indicated by LC50 value. This study used experimental methods conducted in the Laboratory of Farmakoknosi. There are several variations in concentration in this study, namely 10000 ppm, 20000 ppm, 30000 ppm, 40000 ppm, 50000 ppm, 60000 ppm, 70000 ppm, 80000 ppm and replication was done 3 times with total number of test animals used was 270. The results showed that probiotic drink of soursop juice can provide acute toxic effects on test animals with LC50 value of 29717,23 ppm. LC50 values ​​indicate that the mountain soursop probiotic drink is not potentially toxic because it has a value of >1000 ppm.

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)

Study Results

Prasman leaves (Eupatororium triplinerve V) was well documented to have anti cancer benefit in Indonesian traditional medicine history. However, there were no scientific studies including toxicological assessment on the plan extract. The purpose of this study was to investigate the toxicological effect of some fractions of Prasman leaves methanol extract. Phytochemical screening by the Farnsworth method on powder and some fraction of the methanol extract were conducted followed by toxicity test using the “Brine Shrimp Lethality” test (BSLT) method. In the current study results, the phytochemical screening showed the presence of flavonoid, saponin, coumarin, tannin, steroid and volatile oil. LC50 of the n-hexane fraction 238.66 µg/mL, ethyl acetate fraction 24.42 µg/mL,  and n-butanol 64.10 µg/mL.Keywords : BSLT, Toxicity test, Eupatororium triplinerve

Toxicity test and phytochemical screening of ant plant ethanol extract were done. The toxicity test was done by employing the Brine Shrimp Lethality Test (BSLT) method. Sample of ant plant taken from the Aceh Besar forest have been extracted with ethanol. The sample was thenconcentrated using a rotary evaporator until a crude extract was obtained. The extract was tested by toxicity to larva Artemia salina L. Thetoxicity test for larvae Artemia salina Leach have been done by employing the Brine Shrimp Lethality Test (BSLT) method at four concentrationlevels, i.e: 250 ppm, 125 ppm, 50 ppm, and 25 ppm. The result of the research showed that ethanol extract of ant plant Aceh had acute toxicityby LC value 61.11 ppm. The extract had identified were fenolik, saponin, steroid and terpenoid.____________________________________________________________________________________________________________________Key words: rine Shrimp Lethality Test, LC5050, Ant Plant, Aceh, Bphytochemical Screening
