Abstract：‘Huangjincha’is a tradtional and local tea germplasmresource in Xiangxi， with an excellntflavorquality， especially its obvious aroma characteristics， which is highly favored by consumers.This study selected four tea cultivars，namely‘Baojing Huangjincha1’‘Huangjincha 2’，Huangjicha 8’，Huangjincha 18’，to produce ‘Huangjincha’ green and black tea samples. Sensory evaluation， gas chromatography-mass spectrometry （GC-MS）， and relative odor activity value （ROAV） were used to analyze their aroma components. The results show that ‘Huangjincha’ green tea is characterized by its fresh and elegant aroma and a refreshing，sweet aftertaste，while ‘Huangjincha’black tea exhibits distinct sweet and floral notes.A total of101 volatile aroma compounds were detected in ‘Huangjincha’ green tea. Among these， esters and alcohols accounted for 34.4% to 53.5% and 21.9% to 36.3% ，respectively.A total of140 volatile aroma compounds were detected in‘Huangjincha’black tea，with alcohols， esters， and aldehydes being the main volatile components， accounting for 38.6% to 60.0% 11.0% to 26.9% and 9.7% to 17.8% ， respectively. The primary aroma-contributing compounds of both ‘Huangjincha’ green and black tea were further screened.A total of 20 compounds were identified as key contributors to the aroma of ‘Huangjincha’ green tea， including linalool，3，5-octadien-2-one，cis-jasmone， β -ionone，lauric acid， β -cyclocitral，and 2-pentylfuran. For‘Huangjincha’ black tea，33 shared keyaroma components compounds were identified，including linalool， benzaldehyde，3，5-octadien-2-one，trans- ⋅β -ionone， （Z） -linalool oxide（furanoid） and 4-heptenal. This study had preliminarily revealed the similarities and differences in aroma quality characteristics and chemical composition in ‘Huangjincha’green and black tea made by different cultivars，which could be used to improve the processing technology system of‘Huangjincha'.
