Journal Title: INTERNATIONAL JOURNAL OF RECENT TRENDS IN SCIENCE AND TECHNOLOGY - Year 2016, Vol 20, Issue 2
Abstract
Wound infections are problematic because it delays healing encourages scarring and may result in bacteraemia, sepsis or multiple organ dysfunction. Bacteria are most common pathogens colonizing wounds. Aster (Callistephus chinenesis) and Calendula officinalis (Asteraceae) is an aromatic annual herb, which is used in traditional system of medicine to treat various diseases like anti-inflammatory, antispasmodic and antitumor activity. In the present study antibacterial and antioxidant activity of cold floral extracts of Aster and Calendula species are determined. The skin pathogens were isolated from clinical sample of various types of skin aliments. The antibiotic sensitivity pattern was determined. The selected isolates were resistant to various antibiotics like Tetracycline, Erythromycin, Penicillin, Amoxicillin, Naladixic acid and Ciprofloxacin. The antibacterial activity was assessed using modified agar cup method followed by Agar dilution method. Although all the extracts showed significant antibacterial activity but highest antibacterial activity was observed with cold water and alcohol extract of Aster followed by Calendula. The antioxidant activity was determined using DPPH method. All the extracts showed significant antioxidant activity. Thus, these extract would be an ideal alternative that could be used in therapeutic preparation against skin infections.
