| dc.description.abstract | This study aimed to identify, classify and determine the zoochemical properties of the different brittle star species at Barangay Culat, Casapsapan beach, Casiguran Aurora. Abiotic factors were determined such as salinity, temperature and pH using multiparameter probe. Ecological and habitat assessment were computed such as: Frequency, Relative Frequency, Density, Relative Density, Dominance, Relative Dominance, Shannon's Diversity Index and Hill's Number. methanol was used as a solvent for zoochemical analysis and Thin Layer Chromatography was the method used in assessing its secondary. Brittle stars were identified and classified into five (5) species namely: Breviturma brevipes, Ophiocome scolopendrina, Breviturma dentata, Ophiocomaaethiops and Ophiocoma erinaceus, B. brevipes was observed to have the highest frequency of 24.21%. However, B. dentata listed the most dominant with the value of 36.80%. The computed diversity index was 1.49 which is considered very low. Secondary metabolites were determined using Thin layer chromatography and different brittle stars extracts revealed the presence of anthraquinones, anthrones, tannins, flavonoids and alkaloids. The results of the study demonstrated the possibility of obtaining pharmacological property in brottle stars. | |
