Tobacco smoking remains a leading cause of preventable diseases and premature death in many countries. Many smokers want to quit smoking but are not offered the highly effective treatments available to manage tobacco dependency. There has been a current trend for researchers to find new natural ingredients that were safe and still effective in treating tobacco dependence. BTL tea was a herbal-derived product prepared from Herba Menthae, Pogos cablin (Blanco) Benth., Zingiber Officinale Rosc., Flos Chrysanthemi, Radix Glycyrrhizae, Pericarpium Citri deliciosa, and Flos Lonicera. At this time, the safety of this product has not been reported. Thus, this study aimed to evaluate BTL tea’s acute and subchronic toxicity through oral administration in experimental animals. The acute toxicity was determined by Litchfield-Wilcoxon method in mice at the doses of 45.0 g/kg b.w/day to 112.5 g/kg b.w/day. The subchronic toxicity was evaluated following WHO and OECD’s Guidelines in rats with oral doses of 1.08 g/kg b.w/day (equal to recommended human dose) and 3.24 g/kg b.w/day (three times as high as recommended human dose) for four consecutive weeks. As a result, in the acute toxicity test, the mice showed no abnormal sign or death. The subchronic toxicity test, hematological indexes, hepato-renal functions, and microscopic images of liver and kidney were unchanged. However, compared with the control group, there were significant differences in various indexes, including total WBC, lymphocytes, neutrophils, and AST level, but the levels were still safe. In conclusion, BTL tea does not appear to produce acute and subchronic toxicities in mice and rats.

Withania frutescens (W. frutescens) is a medicinal plant widely used to treat several diseases. This work aims to study phytochemical composition as well as acute and subacute toxicity of W. frutescens hydroethanolic extract in mice. The phytochemical composition of W. frutescens extract was performed using gas chromatographic analysis. Acute toxicity was studied in vivo with oral administration of single doses 400 mg/kg, 1000 mg/kg, and 2000 mg/kg for 14 days. Subacute toxicity was studied with the administration of repeated doses of 400 mg/kg/day and 2000 mg/kg/day for 28 days. Phytochemical analysis of W. frutescens hydro-ethanolic extract confirmed the presence of interesting chemical compounds. Acute toxicity results showed no toxic symptoms in mice treated with an increasing dose up to a maximum of 2000 mg/kg. Alongside acute toxicity, subacute data showed no clinical symptoms nor biochemical or histological alteration in mice treated with an increasing dose up to a maximum of 2000 mg/kg compared to the control group (p < 0.05). This study shows no toxic effects in animals treated with W. frutescens extract, and, therefore, this plant can be considered safe in animals up to 2000 mg/kg under both acute and subacute toxicity conditions.

Objective: This study aimed to evaluate the toxicological potential of the ethanol extract of Holothuria atra through the acute oral toxicity – acute toxic class method. Methods: The sample was immersed in ethanol for 72 h at room temperature and repeated 3 times. The extracts were evaporated using a vacuum rotary evaporator. The identification of compounds in the ethanol extract of H. atra was carried out using liquid chromatography–mass spectrometry (LCMS) analysis. The acute toxicity test was examined the effects of treating male mice with the ethanol extract of H. atra at 300 and 2000 mg/kg by oral administration for 14 days. On the past day of the toxicity test, liver of all experimental animals was taken for histopathological testing. Results: LCMS analysis showed that the ethanol extract of H. atra is contained polar compounds (chlorogenic acid, coumaric acid, a glycosaminoglycan, and holothurin) and non-polar compounds (fatty acids). Acute toxicity study was performed at a dose of 300 and 2000 mg/kg for 14 consecutive days. No deaths or behavioral changes were observed during the administration of both doses. Histopathological test results on the liver showed a few changes at doses of 2000 mg/kg. Conclusions: The LD50 is equal to 5000 mg/kg and the ethanol extracts of H. atra can be classified as practically nontoxic. However, further studies are required to proceed to clinical studies in humans.

The herb frequently used as spices or remedies in the Indonesian community, with the seed as the most common part is kapulaga (Amomum cardamomum). According to earlier evidence, this possessed antibacterial, antifungal and several biological properties, reduced blood glucose and atherogenic parameter, and is developed as standardized herbal cures. However, the application of herbal medicine requires validating evidence of safety and effectiveness, including toxicity tests, particularly in clinical settings. The target organs in this comprised hepar, due to the role in several drug metabolism. This study aimed at discovering the safety profile of kapulaga seed extract based on the hepatic transaminase enzyme (SGOT and SGPT) level, by conducting an acute toxicity test in Winstar rats. Also, this was implemented with the OECD 420 Fixed-Dose Procedure, and the preliminary test employed 300 mg/kg BW dose followed by a maximum single quantity (2000 mg/kg BW) of kapulaga. The main test was executed by a separation into control and treatment groups of 5 rats each. Therefore, a single dose of 2000 mg/kg BW kapulaga seed extract was administered to the treatment group, while the control group received standard pellets and water ad libitum. The blood from orbital vein was acquired on day 14, and SGOT and SGPT were subsequently assessed by an enzymatic-photometric method. Also, this data was analyzed using an independent sample t-test, and the mean of SGOT in both groups were 116.92±22.35 and 98.02±16.38 (p=0.17), with 58.72±8.79 and 47.64±7.30 (p=0.06) as SGPT respectively. Therefore, there was no statistical difference, and no acute toxicity signs were discovered. The maximum dose was not toxic and did not result in poisonous symptoms or alter hepatic transaminase enzyme (SGOT and SGPT) in rats.Keywords: Amomum cardamomum, kapulaga, acute toxicity, SGOT, SGPT  Uji Toksisitas Akut Ekstrak Biji Kapulaga (Amomum cardamomum) Berdasarkan Kadar Enzim Transaminase Hepar Tikus WinstarAbstrakKapulaga (Amomum cardamomum), merupakan salah satu herbal Indonesia yang secara umum dimanfaatkan sebagai rempah-rempah maupun obat, terutama bagian biji. Beberapa bukti sebelumnya menunjukkan bahwa kapulaga memiliki berbagai aktivitas biologis seperti antibakteri, antijamur, dan sudah dibuktikan mampu menurunkan glukosa darah dan parameter arterogenik. Bukti tersebut mendukung pengembangan kapulaga sebagai obat herbal terstandar. Penggunaan obat herbal terutama di klinik harus didukung dengan adanya bukti keamanan maupun efektivitasnya termasuk uji toksisitas. Hepar merupakan salah satu target organ dari uji toksisitas karena perannya yang penting pada metabolisme sebagian besar obat. Penelitian ini bertujuan untuk menilai profil keamanan ekstrak biji kapulaga melalui uji toksisitas akut menggunakan tikus Winstar berdasarkan kadar enzim transaminase hepar (SGOT dan SGPT). Uji toksisitas akut berpedoman pada OECD 420 Fixed Dose Procedure. Uji pendahuluan menggunakan ekstrak biji kapulaga dosis 300 mg/kg BB dan diikuti dengan dosis tinggi 2000 mg/kg BB yang diberikan secara tunggal. Uji utama dilakukan dengan membagi tikus ke dalam kelompok kontrol dan perlakuan, masing-masing kelompok terdiri atas 5 tikus. Berdasarkan hasil uji pendahuluan, uji utama menggunakan dosis tunggal 2000 mg/kg BB untuk kelompok perlakuan, sedangkan kelompok kontrol hanya mendapatkan pelet dan air secukupnya. Pada hari ke-14, darah dari vena orbital diambil, lalu kadar SGOT dan SGPT diukur menggunakan metode enzymatic-photometric. Independent sample t-test digunakan untuk menilai data rata-rata kadar SGOT dan SGPT dari kedua kelompok. Rata-rata kadar SGOT pada kelompok kontrol dan perlakuan sebesar 116,92±22,35 dan 98,02±16,38 (p=0,17), sedangkan rata-rata SGPT sebesar 58,72±8,79 dan 47,64±7,30 (p=0,06). Perbedaan rata-rata SGOT dan SGPT pada kedua kelompok tersebut secara statistik tidak bermakna dan tidak ditemukan tanda toksisitas pada semua hewan coba. Ekstrak biji kapulaga dosis maksimal 2000 mg/kg BB tidak toksik pada hepar tikus karena tidak menimbulkan tanda toksisitas maupun mengubah enzim transaminase hati (SGOT dan SGPT). Kata kunci: Amomum cardamomum, kapulaga, toksisitas akut, SGOT, SGPT

Abstract: Toxicity Test Of Acute Industrial Waste Water On Tilapia Fish (Oreochromis Niloticus). The sasirangan industrial liquid wastes containing high ammonia and high pH when discharged into the receiving water body without treatment will result in changes in water quality and even the death of aquatic biota so that an acute toxicity test is necessary. This study aims to determine the value of LC50 from waste sasirangan against tilapiaI. This research used the experimental method of Post Control Only Control Group Design design. Samples taken as much as 100 liters of waste in one industry sasirangan existing in the city of Banjarmasin. Concentrations of the sasirangan waste solution to be used in the acute toxicity test are: 4, 8, 12, 16 and 20%. Parameters studied include ammonia, DO, pH, and temperature. To determine the value of LC50 using probit analysis. The results showed that LC50 for exposure time 24, 48, 72 and 96 hours were 14.73%, 10.21%, 8.26%, and 7.35%, respectively. The results of the analysis show that pH and ammonia content of industrial effluent sasirangan affect the death of tilapia fish. This research is hoped that the sasirangan industry does not dispose of its waste directly to the water body but needs to process it first. For further research it can complement the untested parameters such as BOD, COD, and TSS that affect fish survival.
