摘要

Curcuma longa(turmeric)based products namely curcumins I,II,III,alkyl ether derivatives of curcumin-l and turmeric oil were evaluated for their antifungal activity against two phytophagous fungi Helminthosporium oryzae and Fusarium solani.The most effective turmeric oil exhibited IC_(50)of 12.7 mu g mL~(-1)against H.oryzae and 19.73 mu g mL~(-1)againstF.solanii.Curcumin-IIl with respective IC_(50)of 18.9 mu/g mL~(-1)and 49.3 mu g mL~(-1)was next in order followed by curcumin-II(IC_(50)65.5 and 74.4 mu g mL~(-1))and curcumin-l(IC_(50)80.2 and 135.9 mu g mL~(-1)).Alkylation of curcumin-l did not result in products with improved efficacy.
