Eleutherine bulbosa (Mill.) Urb come from the Iridaceae family, this species contains secondary metabolites in the form of flavonoids and quinones. This research method includes Brine Shrimp Lethality Test (BSLT) toxicity using Artemia salina Leach larvae to determine the LC50 value. This study used experimental methods pharmacologically using a completely randomized design in the same direction pattern in the selection of test animals, 25 animals used were white mice divided into 5 groups with 5 mice per group, with 4 hours observed to find out toxic symptoms and continued observation every 24 hours to see death. Testing of BSLT results showed that ethanol extract had LC50 toxicity = 66.68 ppm (very toxic category), n-hexane fraction had LC50 toxicity = 47.64 ppm (very toxic category), chloroform fraction had LC50 toxicity = 295.1 ppm ( toxic category), and the water fraction has a toxicity of LC50 = 194.54 ppm (very toxic category). The chloroform fraction is an active fraction. Acute toxicity test LD50 value according to the calculation method of Miller Tainter Probit (187,499 mg/KgBB), the method of calculation of Thompson Weil (182,810 mg/KgBB), how to calculate Indonesian Pharmacopoeia (187,068 mg/KgBB). Based on the three calculations, the LD50 value is in the medium category (50-500 mg/kgBB).

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.

ABSTRACTGuava is one of the plants that can traditionally be used for the treatment of diseases. Many kinds of guava, one of which is the Australian guava has the characteristics of roots, stems, leaves, dark red fruit. This study aims to determine the toxicity of the ethanol extract of Australian guava leaves (Psidium guajava L) using the BSLT (Brine Shrimp Lethality Test) method and determine the chemical content of Australian guava leaves (Psidium guajava L). The extract was made by the ultrasonic method using 96% ethanol solvent. Toxicity tests were carried out using 48-hour-old Artemia salina Leach shrimp larvae. The toxic effect of the extract was identified by the percentage of shrimp larvae mortality using probit analysis (LC50). From the research results, phytochemical content includes tannins, flavonoids, alkaloids, terpenoids and saponins, and flavonoid compounds have the highest content compared to the others. Research shows that the ethanol extract of Australian guava leaves is of a moderate category (LC50 441,977 ppm).Keywords :Australia guava leaves, BSLT, Artemia salina L, Ultrasonic

Abstract: Papaya tree is one of the medicinal plant types which advantages for traditional medicine. The flavonoid, alkaloid and saponin were the compounds of papaya leaves. There potentially as cytotoxic for certain levels. The purpose of this research is to determine the potency cytotoxic ethanol extract papaya leaves against Artemia salina Leach larvae using Brine Shrimp Lethality Test (BSLT) method. Research method by quasi experimental, and purposive sampling used 360 Artemia salina Leach larvae divided to 5 groups treatment. Each group contains 15 larvaes. Each group is done by the replication of research for 4 times. The extract concentration are 1000, 750, 500, 250, 100 and 0 µg/ml as a negative control. Data have been obtained by calculating amount of died larvae 24 hours after treatment. Mean percentage larvae death in the concentration of 1000, 750, 500, 250, 100 and 0 µg/ml consecutively were 95%, 78,33%, 53,33%, 36,67%, 21,67% and 0%. Through the data, LC50 value was analyzed by probit analysis using Microsoft offce excel. The higher of extract concentration cause higher percentage death of the larvae. This result shows that LC50 value of ethanol extract of papaya leaves is 285,693 µg/ml (less than 1000 µg/ml). The conclusion is the ethanol extract of papaya leaves had acute toxicity potency against Artemia salina Leach larva according to Brine Shrimp Lethality Test (BSLT). Abstrak: Tanaman pepaya merupakan satu diantara jenis tanaman obat yang umum dimanfaatkan oleh masyarakat secara empiris untuk pengobatan secara tradisional. Tanaman ini mengandung senyawa flavonoid, alkaloid dan saponin. Senyawa tersebut diduga berpotensi sebagai sitotoksik pada kadar tertentu. Tujuan dari penelitian ini adalah untuk mengetahui potensi sitotoksik ekstrak etanol daun pepaya (Carica papaya L.) terhadap larva Artemia salina Leach dengan metode Brine Shrimp Lethality Test (BSLT). Metode penelitian ini berbentuk eksperimental semu dengan menggunakan 360 ekor larva Artemia salina Leach yang dibagi dalam 5 kelompok perlakuan. Tiap kelompok terdiri dari 15 ekor. Tiap kelompok dilakukan pengulangan percobaan 4 kali. Konsentrasi ekstrak berturut-turut adalah 1000, 750, 500, 250, 100 dan 0 µg/ml sebagai kontrol negatifnya. Data diperoleh dari menghitung jumlah larva yang mati 24 jam setelah perlakuan. Rata-rata persentase kematian larva pada konsentrasi 1000, 750, 500, 250, 100 dan 0 µg/ml berturut-turut adalah 95%, 78,33%, 53,33%, 36,67%, 21,67% dan 0%. Berdasarkan data, LC50 ekstrak etanol daun pepaya ditentukan dengan analisis probit menggunakan Microsoft offce excel. Semakin tinggi konsentrasi ekstrak menyebabkan semakin tinggi persentase kematian larva. Hasil penelitian ini menunjukkan harga LC50 dari ekstrak etanol daun pepaya adalah 285,693 µg/ml (kurang dari 1000 µg/ml). Hal ini menunjukkan bahwa ekstrak etanol daun pepaya memiliki potensi toksisitas akut terhadap larva Artemia salina Leach dengan metode Brine Shrimp Lethality Test (BSLT).
