At the same time leaf extracts with different solvents displayed broad spectrum of antibacterial activity against panel of significant pathogens including human and phytopathogens. Similar earlier reports reveal the presence of almost same phytochemical components when methanolic extract of C. lanceolatus DC. evaluated. 26 The presence of triterpenoids, 10 volatile oils, 27 polyphenols 28 and 29 see more and flavones
30 were recorded from the earlier studies. The significant antibacterial activity against resistant strain S. aureus was observed in a methanolic, petroleum ether leaf extracts. Perusal of reports by far represents essential oils from C. citrinus and C. viminalis exhibiting strong zone of inhibitions against S. faecalis (20.3–24.0 mm), both strains of S. aureus (23.0–26.3 mm), B. cereus (17.3–19.0 mm)
and S. marcescens (11.3–23.7 mm). The MIC values of both essential oils ranged from 0.31 to 2.50 mg/ml. 31 Whereas antimicrobial activity from essential oil of C. comboynensis showed significant effect against B. Selleckchem GDC0199 subtilis and S. aureus, P. vulgaris, P. aeruginosa and C. albicans. 32 Similarly the essential oil of C. lanceolatus showed effective against S. aureus and K. pneumoniae. 33 The petroleum ether leaf extract of C. lanceolatus showed significant activity against X. campestris pv. vesicatoria (35 mm) compared to the other report which has showed 14.5 mm zone of inhibition in an aqueous bark extract against
X. campestris pv. campestris. 34 With these reported literature and obtained results in the present investigation represents plants as source of therapeutic potential. Appearance of resistant microorganisms has upsurge for novel therapeutic agent from plant resources which are more safe, eco-friendly, selective and efficacious natural products. The drug discovery pipeline in modern-drug discovery is getting dry Isotretinoin and modern world is looking toward the herbal world with great expectations. Thus present study reinforced the assumption that medicinal plants could be a promising source of antimicrobial substances and the antibacterial potential of C. lanceolatus leaf extract has been determined for the first time against phytopathogenic bacteria. Pharmaceutical biology perceives plant as a reservoir of bioactive compounds and is being explored for the discovery of new therapeutic agents. Research on this area has been one of the top priorities in the current scenario to combat various infectious diseases which has become life threatening globally. The finding of the present investigation is a promising enough for further study and will be valuable to reveal any novel compound attributes to the field of pharmaceutical importance as well as a step toward crop protection.
