Abstract:
Objective To investigate the antimicrobial and antitumor activities of extracts from the root of mangrove plant,Kandelia candel.Methods Micro-dilution and MTT method were used to test the antimicrobial and antitumor activities of extracts from the root of K.candel.Results The petroleum ether extracts of root could inhibit the growth of Staphylococcus aureus,S.epidermidis,Bacillus subtilis and Sarcina lutea with the minimal inhibitory concentration(MIC) of 3.125 mg?mL-1,1.5625 mg?mL-1,0.78125 mg?mL-1 and 3.125 mg?mL-1 respectively.The ethyl acetate extracts and ethyl alcohol extracts could inhibit the growth of S.epidermidis with MIC of 3.13 mg?mL-1 and 6.25 mg?mL-1 respectively.At the same time,the petroleum ether extracts could inhibit the proliferation of tumor cells,such as SMMC-7721,B16,BGC803 and HepG2 with IC50 of 355.2?g?mL-1,378.6?g?mL-1,275.6?g?mL-1 and 411.6?g?mL-1 respectively,while the other extracts could stimulate the proliferation of tumor cells apparently.Conclusion The antimicrobial and antitumor activities of extracts from the root of K.candel indicate the potential pharmaceutical usage of this plant.
