| Summary: | <em>Dendrophthoe falcata</em> (L.f.) Ettingsh is a hemiparasitic plant, used in Sri Lankan and Indian indigenous medicine to treat various diseases such as asthma, cancerous tumors, diabetes and wounds. Despite the hemiparasite on the host <em>Limonia acidissima</em> is used to treat various diseases, any bioactivity study of <em>Dendrophthoe falcata</em> grown on the particular host has not been conducted yet. This study aimed to investigate several bioactivities of the hemiparasite grown on <em>Limonia acidissima</em> (<em>La</em>) and compare with that grown on <em>Mangifera indica</em> (<em>Mi</em>). Sequential extracts by Soxhlet method from hexane (<em>La</em>-HE and <em>Mi</em>-HE), ethyl acetate (<em>La</em>-EAE and <em>Mi</em>-EAE) and methanol (<em>La</em>-ME and <em>Mi</em>-ME) were investigated for bioactivities. Antioxidant activity was determined using DPPH radical scavenging assay in which <em>Mi</em>-ME and <em>Mi</em>-EAE showed the highest activity, that is five times more than that of α-tocopherol. Brine shrimp lethality assay was conducted as a preliminary toxicity assay, where <em>La</em>-EAE showed the highest activity that is approximately four times that of K<sub>2</sub>Cr<sub>2</sub>O<sub>7</sub>. The total polyphenolic content was determined by Folin-Ciocalteu method in which both methanol extracts showed the highest polyphenolic content of which <em>Mi</em>-ME was approximately four times more than that of <em>La</em>-ME. These results suggest that the bioactivity of the hemiparasite vary considerably with the host. Further, extracts of the hemiparasite on <em>Limonia acidissima</em> showing high antioxidant activity coupled with high toxicity justifies its applicability in indigenous medicine. |
