Antimicrobial and antioxidant test of several mistletoe extracts (Scurrula ferruginea (Roxb. Ex.Jack) Danser) from avocado plants

Scurrula ferruginea (Roxb. Ex. Jack) Danser is a mistletoe plant which is used by the community as a medicine for lowering blood pressure, cough medicine, diabetes, diarrhea, wounds, smallpox, skin infections, ulcers, diuretics and hypertension. This study aims to determine the antimicrobial potential, determine the Minimum Inhibitory Concentration (MIC) and Minimum Lethal Concentration (MLC) as well as determine the antioxidant activity and total polyphenols from fresh, boiled and steeped extracts of mistletoe (S. ferruginea) from avocado plants. The microbial tests used in this study were S. aureus, E. coli, and C. albicans. This study carried out in experimented methods and designed in nested pattern. The results showed that the inhibition zone of the avocado parasite extract had a significantly different effect on S. aureus and E.  coli, but did not have a significantly different effect on the C. albicans test microbe. The MIC of fresh extract is true against S. aureus and E.coli which is 6.125% with 50% MLC. The optimal antioxidant value was obtained from fresh mistletoe extract with an IC50 value of 117.8 µg/ml in the medium activity category and the highest total polyphenols obtained from fresh extract was 67.80 mg. GAE/ml.
