Abstract

Bioactive compounds from the sea which are generally in the form of secondary metabolites have the potential to be developed as medicinal ingredients. Marine life can be used as an object of research and development, considering the many benefits that can be taken from the secondary metabolite compounds contained in it, especially compounds that have bioactivity. Soft corals are marine biota that have bioactivity, extracts from sost coral contain bioactive compounds that have cytotoxic, anti-tumor, anti-viral, anti-inflammatory, anti-fungal, anti-leukemic, and enzyme activity inhibitory properties. Some of the research results show that marine soft corals have a variety of structures and biological activities including antioxidant substances. Soft corals were extracted by maceration method and then evaporated. The cytotoxic activity of soft coral extract was tested using the BLSA method and then analyzed the data to find the concentration of mortality (LC50). The purpose of this study was to test the cytotoxic activity of soft coral Xenia sp. The results of this study were testing the cytotoxic activity of the sample Xenia sp., amounting to 20.89 ppm, and having strong toxic properties.

Abstract

Secondary metabolites produced by marine organisms commonly have unique chemical structures and very interesting pharmacological activities. Marine organisms that have the most chemical conent are produced by marine invertebrates, followed by marine plants. Groups that include marine invertebrates include: sponges, bryozoans, cnidarians and tunicates. Soft coral, which is one of the marine invertebrates, has biological activities, such as antifungal, cytotoxic, antineoplastic, antimicrobial, HIV inhibitor and anti-inflammatory. This study aims to determine the  value of the soft coral extract Cespitularia sp. taken from Manado Bay by the Brine Shrimp Lethality Assay (BSLA) method. This toxicity test was carried out quantitatively by analyzing data based on the number of deaths caused by the test extract of Artemia sp. The results obtained based on data analysis namely the value of the soft coral extract Cespitularia sp. is 53.27 ppm, this means that the extract can be developed as an anticancer drug candidate due to below below to 1000 ppm. Soft coral Cespitularia sp. categorized as toxic based on the Meyer classification or moderately toxic based on the Tanamatayarat classification and very toxic based on the Clarkson classification.Keywords: Soft coral; Cespitularia sp.; Toxicity;

Abstract

Ascidia Eudistoma sp. produce bioactive compounds that can inhibit the growth of microorganisms. Ascidians are also known for their potential secondary metabolites in the biomedical world. This study aimed to obtain isolates of the ascidia symbiont Eudistoma sp., determine the antifungal activity against the test fungus Candida albicans, and determine the anti-UV activity of the symbiont Eudistoma sp. The ascidia symbiont fungus was extracted using maceration method with ethyl acetate solvent and tested for antifungal activity using the test fungus Candida albicans. The antifungal activity test results showed that the diameter of the AFBN 5b inhibition zone of 9 mm. The symbiont fungus can be said to have potential as an antifungal drug.  Testing the anti-UV activity of fungi in symbiosis with ascidia Eudistoma sp. using a spectrophotometer showed that the extract sample of the ascida symbiont fungus could produce an absorption at UV-B (λ 290–320 nm) of 3.8 absorbance and when compared to UV-A (λ 370–400 nm) an absorption value of 0.38 was obtained and is still classified as moderate Keywords: Ascidia, Eudistoma sp., symbionts, Antifungal and Anti-UV

Abstract

The purpose of this study was to determine the composition of nematocysts in the body tissue of the coral fungia, C. vaugani.  The location for the collection of C. vaugani colonies was on the coral reefs of the Malalayang coastal area, Manado. This research was carried out in September - December 2020. The observation of nematocysts of C. vaugani was carried out using an Olympus CX41 microscope with a magnification of x100 objective lens which connected to a computer monitor equipped with an optical view 7 application at the Fish Health Environment and Toxicology Laboratory, Faculty of Fisheries and Marine Science, UNSRAT.  The present results showed that C. vaugani had a composition of nematocysts, namely type I microbasic p-mastigophore (MpM-I) of 40.00%, small type II microbasic p-mastigophore (sMpM-II) of 31.11%, small holotrichous isorhizas (sHI) of 24.44 %, large type II microbasic p-mastigophore (lMpM-II) of 2.22%, and large holotrichous isorhizas (IHI) of 2.22%.  sMpM-II is the most dominant nematocyst type of C. vaugani and this type of nematocyst is thought to be used by coral for aggression and killing prey or predator if there is disturbance from the surrounding aquatic environment where the coral lives.  Further research is recommended to study the types and morphology of nematocyst from various species of coral fungia, including C. vaugani to understand the differences in their types and dimension of the nematocyst. Keywords: Composition, Cycloseris vaugani, Fungia, Manado, nematosit
