GB/T 14454 "spice general test method" consists of the following components.

--- Part 1. perfume sample preparation;

--- Part 2. spice aroma evaluation method;

--- Part 4. Determination of the refractive index of spices;

--- Part 5. Determination of optical rotation of spices;

--- Part 6. assessment perfume evaporation residue content;

--- Part 7. Determination of spices freezing point;

--- Part 11. Determination of phenol content of spices;

--- Part 12. Determination of trace chlorine spices;

--- Part 13. Determination of carbonyl value and carbonyl compounds content;

--- Part 14. Preparation of spices standard solution, the test solution and the indicator solution;

--- Part 15. Determination of sassafras safrole and safrole exclusive content packed column gas chromatography.

This is Part 15 GB/T 14454 of.

The partial modification of international standards ISO 7355. 1985 "sassafras and nutmeg oil safrole and cis, trans - different safrole content measured Given Packed Column Gas Chromatography. " This part of ISO 7355. 1985 as compared to the main technical differences are as follows.

--- Increasing the reference retention index;

--- Remove the ISO 7355. 1985 superposition method.

This part is GB/T 14454.15-1993 "sassafras safrole and safrole different Determination of Packed Column Gas Chromatography Amendment Act ". This section compared with the GB/T 14454.15-1993, mainly made editorial changes.

Appendix A of this section is an informative annex.

This part is proposed by the China National Light Industry Council.

This part of the National Fragrance Flavor and Cosmetic Standardization Technical Committee.

This section is responsible for drafting the Shanghai Institute of spices.

Introduction

Since the description of gas chromatography is very lengthy, so that the following approach is useful. On the one hand the development of common methods, pointed out that Detailed information about the common parameters, equipment, products, methods, formulas, and other aspects; the other hand, the determination to develop a more specific brief essential oil component Standard, given only for specific operating conditions.

This section references General Standard GB/T 11539 General Chapter "spice Packed Column Gas Chromatography common law".

Determination of sassafras safrole and safrole exclusive content Packed Column Gas Chromatography

1 Scope

This section GB/T 14454 specifies the determination of the oil content of sassafras safrole and iso-safrole by packed column gas chromatography.

This section applies to the determination of safrole and safrole different content in sassafras oil.
