Benzenoids together with isoprenoids dominated the scent in all species. Among the benzenoids, benzaldehyde (Silene subconica 35.5%, Silene succulenta 23.1%, Silene sericea 15.6%, Silene vulgaris 12.2%, and Silene nutans 9.9%), methylbenzoate (Silene saxifraga 96.1%, S. succulenta 15.2%), benzyl acetate (Silene dichotoma 37.8%, S. nutans 30.1%, Silene italica 9.0%, and Silene latifolia 5.5%), or benzyl alcohol (Silene viscosa 36.1%) occur in the largest amounts. p-Cresol is only found in the floral scent of S. dichotoma (28.5%). Among the isoprenoids, monoterpenes occur in the largest amounts (myrcene 23% in Silene chlorantha, trans-beta-ocimene 27.2% in S. nutans and 34.9% in S. sericea, fenchyl acetate 12.7% in S. chlorantha, beta-linalool 40.5% in S. chlorantha and 14.5% in S. italica). Relatively high amounts of lilac compounds occur in S. latifolia (49.1%), Silene otites (35.7%), S. subconica (15.2%), and S. vulgaris (59.6%). Higher amounts of sesquiterpenes (isoprenoids) were only found in Silene vallesia with beta-bourbonene and gamma-muurolene. 收起
