Abstract

Malaria remains the most devastating infectious parasitic disease, inflicting both death and economic losses on at least half the world's population. Numerous attempts have been made to control the disease using vector control measures and/or chemoprophylaxis. Antimalarial drugs have a selective action on the different phases of the parasite life cycle. Mechanism of antimalarial drugs action will be discussed in this article.

Abstract

The Indonesian people empirically use Sidaguri (Sida rhombifolia L.) in medicine, such as anti-hyperuricemia. Herbal-based treatment is currently much preferred. Drug metabolism, in general, mainly occurs in the liver, so the possibility of damage to this organ is high. This study aims to determine the acute toxicity category of 96% ethanol extract of sidaguri based on the LD50 value, changes in body weight, changes in organ weight, and macro pathology in the organs of male DDY mice in vivo. The method used in this research was experimental with a fixed dose design following the Indonesian Food and Drug Authority regulations regarding guidelines for in vivo non-clinical toxicity tests. The test group was divided into six dose groups (standard, 50, 300, 2000, 5000, and 15000 mg/kg Body of weight). Observations were made for 24 hours. Observations were continued for 14 days on death parameters, toxicity symptoms, body weight, and relative organ weights using five main organs (heart, lungs, liver, spleen, and kidneys, and pathological examination). The acute toxicity test results showed no death in all dose treatment groups. Macropathological analysis did not show abnormalities in organs in all groups of mice. LD50 value is more than 15000 mg/kg. Sidaguri 96% ethanol extract is safe and Practically non-toxic.

Abstract

Sea cucumbers are deep-sea-dwelling invertebrate animals that are rich in nutrients and have been empirically used to prevent various degenerative diseases, especially due to their ability to dampen free radicals. The purpose of this study was to identify, and determine antioxidant activity, total phenolic content, and toxic properties in extracts of several sea cucumber species originating from Tegal Mas Island, Lampung. The identification results of the three sea cucumber species were Stichopus vastus Sluiter (SV), Stichopus monotuberculatus Quay & Gaimard (SM), and Stichopus quadrifasciatus Massin. (SQ). The extraction was performed by kinetic maceration against all parts of the sea cucumber using a 70% ethanol solvent. Antioxidant activity test using the DPPH (2,2-diphenylpicrilhydrazyl) free radical suppression method and determination of the total phenolic content using the Folin-Ciocalteu method. The results showed that SV had the highest total phenolics and antioxidants with the lowest toxicity. However, optimisation of extraction between wet and dry sea cucumbers is still required. Extraction optimisation with various solvents can also be done to gain secondary metabolites more effectively.
