摘要： 研究了作为云南省主要采脂树种的思茅松松节油标准样品的制备和稳定性、均匀性及其定值方法。思茅松松节油制备采用水蒸气蒸馏法,含量分析采用气相色谱面积归一化法。制备得到的松节油标准样品在36个月内保持稳定,通过了均匀性检验。多实验室联合定值结果为:α-蒎烯含量X标=75.30 %,标准不确定度UA=0.23 %,扩展不确定度U0.95=0.45 %; β-蒎烯含量X标=17.80 %,标准不确定度UA=0.08 %,扩展不确定度U0.95=0.16 %; β-水芹烯含量为X标=3.50 %,标准不确定度UA=0.08 %,扩展不确定度U0.95=0.16 %。

Abstract: The reference material of turpentine oil from Simao pine (Pinus kesiya var. langbiangensis) oleoresin were used to investigate its preparation process, homogeneity, evaluation of stability and certification. Simao pine is the major tapping pine species in Yunnan Province. The turpentine oil was extracted from simao pine oleoresin using a steam distillation method, and the distillate was characterized by a gas chromatographic area normalization. The homogeneity test showed that reference materials of turpentine oil kept stable for 36 months or longer. The certification results showed that the standard content values of 3 indicating components were: α-pinene XS=75.30 % with standard uncertainty UA=0.23 %, extended uncertainty U0.95=0.45 %; β-pinene XS=17.80 %, UA=0.08 %, and U0.95=0.16 %; β-phellandrene XS= 3.50 %, UA=0.08 %, U0.95=0.16 %, respectively.

Key words: turpentine oil of Pinus kesiya var. langbiangensis, reference material, certification
