| Summary: | In this study the plant of Borreria articularies (Linn. F) (family Rubiaceae) were subjected for
phytochemical, antibacterial and antifungal evaluations. The sample powder was subjected to cold
maceration by ethanol and methanol for 48 h at room temperature, concentrated by using a rotary
vacuum evaporator (BUCHI R-205) and drying at −50 °C using bench top freeze dryer (ALPHA 1-4LD-2)
and then kept in the fridge (4°C). Compound identification by comparing the NIST library data of the
peaks with those reported in mass spectra of the peaks with literature data. The in vitro antimicrobial
activities were determined by disc diffusion method and poisoned food technique respectively. Mueller-
Hinton and Sabouraud medium was used for culture of bacteria and fungi. 5% ethanolic solution of the
crude extracts and pure compound were used as the test material. The studies revealed that alkaloids,
glycosides, tanins, flavonoids, saponins and reducing sugars are present in both the extracts. The pure
compound, 6-methyl-5-cyclodecen-1-ol, exhibited good antimicrobial activity against all the pathogens
tested. The highest zone of inhibition 20 mm was exhibited by ethanol and 6-methyl-5-cyclodecen-1-ol
at a concentration of 2,000 μg/disc against both Escherichia coli and Vibrio cholera. The highest
inhibition observed was 55.17 and 53.33% of fungal radial mycelial growth at a concentration of (100
μg/ml) against Aspergillus ustus and Aspergillus ochraceus respectively. The extracts exhibited
antimicrobial activity which could serve as an alternative traditional medicine for treatment as
antimicrobial agent.
