Abstract

To study the main aroma components of Phalaenopsis orchid and their relationship with colors, 10 fragrant cultivars with different colors, like pink, rose, yellow, and purple, were used as samples in this experiment. Headspace-gas chromatography-mass spectrometry was used to determine the main components of floral fragrance and analyze the correlation between floral color and fragrance. The results showed that the main aroma components of the 10 fragrant cultivars of Phalaenopsis were alcohols, alkenes, esters, and benzene ring compounds, and the main aroma components of different cultivars were diverse. The main aroma components of yellow fragrant flowers were esters, alcohols, and alkenes. The purple and pink series were alcohols and phenyl rings. There was a certain correlation between flower color and floral fragrance. There was a significant positive correlation between esters and flower color C* value, and a significant negative correlation between alkenes and flower color h value. There was a significant negative correlation between alcohol and flower color C* value, and a significant positive correlation between alcohol and L* value. The content of benzene compounds was negatively correlated with L* and positively correlated with h value. This may be related to the synthesizing of anthocyanins and benzene ring compounds through the phenylpropanoid metabolic pathway. In this paper, the correlation between Phalaenopsis floral color and fragrance was studied, and the synthetic pathway of floral color and fragrance components was analyzed. The proposed method and research data can provide a theoretical basis for floral color breeding and fragrance synthesis.
