Abstract: | ObjectiveTo evaluate the anticancer, antioxidant and antimicrobial activities along with total phenolic and flavonoids contents extracted from Lespedeza bicolor indigenous to Khyber Pukhtoonkhwa, Pakistan.MethodsAnticancer activity against human lung carcinoma (LU-1) and human prostate carcinoma (LnCap), antimicrobial against Aspergillus fumigates, Aspergillus niger, Fusarium solani, Mucor sp Klebsiella pneumonia and Enterococcus and antioxidant activity on 1,1-Diphenyl-2-picryl-hydrazyl (DPPH) and Hydrogen peroxide radicals scavenging activity were assessed in methanol extract of Lespedeza bicolor.ResultsLespedeza bicolor aerial parts and root extract showed IC50 value of 12.5 and 50 μg/mL against LU-1 whereas, ≤ 12.5 and 12 μg/mL were calculated against LnCap cell line. Minimum inhibition concentration (MIC) value of 20–35 μg/mL has been observed against Aspergillus fumigates, Aspergillus niger, Fusarium solani and Mucor sp in comparision with 1–2.5 μg/mL of Terbinafine used as a standard fungicide. MIC value of 20 and 35 μg/mL of Lespedeza bicolor aerial parts and root extract against bacterial pathogen Klebsiella pneumonia and 20–50 μg/mL against Enterococcus has been measured. DPPH radical scavenging activity of Lespedeza bicolor with IC50 values of ≤ 50 μg/mL and ≤ 200 μg/mL was observed whereas, hydrogen peroxide scavenging activity with IC50 values of ≤ 25 μg/mL for aerial parts and ≤ 50 μg/mL for the root extract of Lespedeza bicolor has been shown.ConclusionThese data suggested that the methanolic extract of Lespedeza bicolor could be potential candidates for natural antioxidants and anticancer. |
