标准范围

ISO 7358规定了一种使用内标或外标的高压液相色谱(HPLC)方法，用于测定佛手柑油[Citrus aurantium ssp bergamia(Risso et Poit.)Wight et Arn.Ex Engl.]、柠檬油[Citrus limon(L.)Burm.f.]、香橼油(Citrus bigaradia Risso)和酸橙油[Citrus aurantifolia(Christm.)Swingle和Citrus latifolia Tanaka]中的bergapten含量，所有这些都在bergapten中完全或部分减少。对于bergapten含量大于或等于1%质量分数的精油，适用内标法。对于质量分数为0.1%至1%的佛手柑素含量的精油，外标法是适用的。

ISO 7358 specifies a high-pressure liquid chromatographic (HPLC) method, using either an internal standard or external standard, for the determination of the bergapten content in oil of bergamot [Citrus aurantium ssp bergamia (Risso et Poit.) Wight et Arn. ex Engl.], in oil of lemon [Citrus limon (L.) Burm. f.], in oil of citron (Citrus bigaradia Risso), and in oil of lime [Citrus aurantifolia (Christm.) Swingle and Citrus latifolia Tanaka], all of them fully or partially reduced in bergapten.For essential oils having a bergapten content greater than or equal to a mass fraction of 1 %, the internal standard method is applicable.For essential oils having a bergapten content from a mass fraction of 0,1 % to 1 %, the external standard method is applicable.
