KOMPONEN FITOKIMIA DAN TOKSISITAS SENYAWA BIOAKTIF DARI LAMUN ENHALUS ACOROIDES DAN THALASSIA HEMPRICHII DARI PULAU PRAMUKA, DKI JAKARTA

Abstract

Some of marine bioactive research has been done using seagrass, such as Enhalus acoroides and Thalassia hemprichii. Respect to the bioactive compound in Enhalus acoroides and Thalassia hemprichii as medicine, and other pharmaceuticals, it is necessary to observations phytochemical components and toxicity level. This study informs the toxicity level and phytochemical compounds which is contained in Enhalus acoroides and Thalassia hemprichii from Pramuka Island, Jakarta. Phytochemical test of Enhalus acoroides and Thalassia hemprichii showed that there are containing flavonoids, alkaloids, and steroids. Toxicity test wich is conducted with Brain Shrimp Lethal Toxic (BSLT) method showed that methanol extract of Enhalus acoroides is highly toxic with LC50 = 5.74 ppm, while the n-hexane extract of Enhalus acoroides is not toxic, indicated by LC50 = 1309.42 ppm.
