雄株和雌株花蜜中的挥发性成分均含有角鲨烯作为主要成分。雄株花序中角鲨烯的含量大约是雌株花序中角鲨烯含量的两倍。此外，花蜜中还含有C-21至C-31碳氢化合物和雄株样品中的十六烷酸乙酯和苄酯，以及C-18至C-23多不饱和脂肪酸作为其他重要的脂肪成分。花蜜中的芳香化学物质由丁烯醇、丁醇和戊醇、苯甲醇和苯乙醇、橙花醇、香叶醇和苯甲酸乙酯、水杨酸和肉桂酸的乙酯组成。雌株花序中苯甲醇的含量约为雄株花序含量的五倍。简要讨论了花蜜挥发性化合物在蝙蝠授粉和负鼠和航鼠取食花序中的重要性。
The volatile fraction of Dactylanthus taylorii flower nectar from male and female plants has been shown to contain squalene as a major constituent. The inflorescence from male plants contained approximately twice the amount of squalene as that detected in the inflorescence of female plants. In addition, the nectar contained C-21 to C-31 hydrocarbons and in one of the male plants samples, ethyl and benzyl esters of hexadecanoic and C-18 to C-23 polyunsaturated fatty acids as other significant lipid components. The fragrance chemicals in the nectar comprised a relatively simple mixture of butenols, butanols and pentanols, benzyl and phenylethyl alcohols, nerol, geraniol and ethyl esters of benzoic, salicylic and cinnamic acids. The inflorescence from female plants contained approximately five times the amount of benzyl alcohol compared with the amount from the inflorescences of male plants. The importance of the nectar volatile compounds in bat pollination and browsing of Dactylanthus inflorescences by possums and ship rats is briefly discussed.
