Piperonylic acid was purchased from commercial sources TCI and used without further purification. Aristolochia is an important genus in the family of Aristolochiaceae and is widespread across tropical Asia, Africa, and South America.

Aristolochia bracteolata – Useful Tropical Plants

Both the piperonylic acid moiety of AA-1 Figure 1 and AAmethyl ester showed no activity against bacteria Bracteolsta 2which suggests that the coexistence of phenanthrene ring and free carboxylic acid is essential for AA-1 antibacterial activity. AA-1 showed strong activity against Moraxella catarrhalis standard strain and clinical isolates and sea urchin-derived Bacillus sp. Technology Biodiversity in India.

Modification of the AA-1 to AA-1 methyl ester completely abolished the antibacterial activity of the compound and the piperonylic acid moiety of AA-1 which suggested that the coexistence of phenanthrene ring and free carboxylic acid is essential aristolcohia AA-1 antibacterial activity. The chloroform soluble fraction was therefore selected for further chromatographic separations and resulted in the isolation of known compound AA-1 Figure 1.

Introduction Moraxella catarrhalis is a gram-negative, aerobic diplococcus human mucosal pathogen which causes middle ear infections bracteloata infants and children [ 1 — 3 ], and it is one of the three major causes of otitis media along with Streptococcus pneumonia and Haemophilus influenzae [ 4 ].

Although AA-1 is highly effective in killing M. Antimicrobial Activity Initial steps in new drug discovery involve identification of new chemical entities, which can be either sourced through chemical synthesis or can be isolated from natural products through biological activity guided fractionation.

The authors would like to thank Dr. A bioassay-guided fractionation of methanol extract of Aristolochia bracteolata whole plant was carried out in order to evaluate its antimicrobial activity and to identify the active compounds in this extract.
