Absrtact：【Objective】Thisstudyaimed toinvestigatethecompositionanddiffrences of volatilecomponentsofflowers oftwosourcitrusvarieties，andprovidesatheoretical basis forthediversifiedandhigh-valueutilizationof citrus germplasm resources.【Method】 Headspace solid-phase microextraction（HS-SPME）coupled with gas chromatographymasspectrometry（GC-MS）was used to analyze the volatile components of the blossoming flowers of two sour citrus varieties.【Result】Atotalof90volatilecomponents weredetected fromtwo typesof sourcitrus flowers.The highestrelative content of volatilecomponents in bothsour citrus flowerswas monoterpenesamong the olefins，followed by terpene alcoholsamong thealcohols.Atotalof63and 62volatilecompounds were detected intheflowers of Fortunellobovata var variegated calamondin and Citrus depressa，respectively.The main volatile components in F .obovatavarvariegated calamondin were β -myrcene （ 31.63% ），linalool （ 24.42% ）， α -farnesene （ 14.74% ），（Z）-3，7-dimethyl-1，3，6-octatriene （ 7.89% ），methyl anthranilate （ 3.54% ），and D-limonene （ 3.00% ）.And the main volatile components in C depressa were β -myrcene （ 36.19% ），linalool（ 15.24% ），methylanthranilate（ 8.56% ）， γ -terpinene（ 7.56% ），（Z）-3，7-dimethyl-1，3，6- octatriene （ 5.70% ），N-phenylformamide（ 4.71% ），and（Z）-3-heptadecene （ 4.06% ）.The contents of components such as linalool， α -farnesene， γ -terpinene，and N-phenylformamide were identified as critical factors contributing to the distinct aroma profiles between the two varieties.【Conclusion】The volatile components ofthe two sour citrus flowers share common characteristics in composition，but exhibit significantdiferences in specificcomponents andtheir contents.
