Abstract: Three oil samples: cold-pressed oil, refined oil, and organic solvent oil were diluted by petroleum ether into different mass concentrations and irradiated by 40 WUV rays. The absorption bands, UV absorption ability of 10% Moringa oleifera oil, and absorbance of 0.1% Moringa oleifera oil were determined. The results showed that the maximum absorption wavelength is 212 nm; cold-pressed oil and organic solvent oil show better anti-UV ability than refined oil; 10%30% Moringa oleifera oil can resist UVB and UVC while 30%100% Moringa oleifera oil can resist UVA, UVB, and UVC; 10% Moringa oleifera oil can absorb short-wavelength UV and partrial mid-wavelength UV; 0.1% Moringa oleifera oil can absorb UVC. The results demonstrated that Moringa oleifera oil own the character of anti-UV ability.

Key words: Moringa oleifera oil, UV rays, transmittance, absorbance
