THE TOXICITY OF MANGOSTEEN RIND EXTRACTS ON DAPHNIA

Abstract

Garcinia mangostana is a tropical tree found across Southeast Asia, Australia and Kerala (India). The fruit has several therapeutic properties and its rind in particular has anti-microbial, anti-malarial, antioxidant and larvicidal activity. The protocol for toxicity was followed as per the OECD guidelines number: 202 and observations were recorded after 24 h and 48 h. The dose- response graph was plotted to determine the EC 50 values.The EC 50 value of the cold extract, Soxhlet extract and microwave assisted extract was found to be 0.51 ppm, 0.49 ppm and 0.83 ppm respectively.
