Control of Fusarium wilt of safflower by mangiferin

Control of Fusarium wilt of safflower by mangiferin. Ghosal, Shibnath; Biswas, Kanika; Chakrabarti, Dilip K.; Chaudhary, Kailash C. Basu (Dep. Pharm., Banaras Hindu Univ., Varanasi, India). Phytopathology, 67(4), 548-50 (English) 1977. CODEN: PHYTAJ. DOCUMENT TYPE: Journal CA Section: 5 (Agrochemicals) The antifungal activity of magniferin (I) [4773-96-0], a naturally occurring xanthone-C-glucoside from Canscora decussata, against Fusarium oxysporum f. carthami was evaluated. Safflower seedlings grown from mangiferin-treated seeds in infested potting soil were protected for up to 2 weeks from infection by 3 strains of the fungus known to cause wilting in safflower. I caused lysis of hyphal cells in vitro and significantly retarded mycelial growth of the fungus. Prodn. of fusaric acid [536-69-6], a normal metabolic product of this fungus, was prevented completely by I, and a different amino acid that was produced was isolated and partially characterized.

Photometric determination of mangiferin

DOCUMENT TYPE: Journal CA Section: 64 (Pharmaceutical Analysis) A photocolorimetric method using comparison with a calibration curve is described for detn. of mangiferin (I) [4773-96-0] in cryst. powder or chromatog. exts. prepd. from honeysuckle stock.
