Publication date: April 2020Source: Biochemical Systematics and Ecology, Volume 89Author(s): Yingchun Zhang, Mei Ge, Xinhui Wang, Yue Zeng, Yixuan Liao, Yapeng Wang, Zhongliang ZengAbstractThe root bark of tree peony (Paeonia suffruticosa Andr.), also called Coetex Moutan (CM), is a traditional Chinese medicine. The medicinal plant is also well known for its beautiful flowers with hundreds of cultivars. CM from different cultivars or grown in various geographic areas are significantly different in quality and chemical properties. So the aim of this study is to develop specific SSRs by transcriptome analysis to distinguish ...

Seasonal and diel variations in scent composition of ephemeral Murraya paniculata (Linn.) Jack flowers are contributed by separate volatile components
Publication date: April 2020Source: Biochemical Systematics and Ecology, Volume 89Author(s): Ishita Paul, Pratap Bhanu Singh Bhadoria, Adinpunya MitraAbstractScent profile of the ephemeral nocturnal floral species Murraya paniculata was characterized to assess diel and seasonal variability. The floral fragrance was found to constitute a characteristic set of 15 major volatile organic compounds (VOCs) dominated by benzenoids, terpenoids and phenylethanoids. Strong diel variability was detected due to dominantly endogenous regulation of 2-phenylethanol and (E)-β-ocimene emission levels, along with temperature-correlated emi...

Carotenoids of dragonflies, from the perspective of comparative biochemical and chemical ecological studies
Publication date: April 2020Source: Biochemical Systematics and Ecology, Volume 89Author(s): Takashi Maoka, Naoki Kawase, Tetsuyuki Ueda, Ritsuo NishidaAbstractCarotenoids of 20 species of dragonflies (including 14 species of Anisoptera and six species of Zygoptera) were investigated from the viewpoints of comparative biochemistry and chemical ecology. In larvae, β-carotene, β-cryptoxanthin, lutein, and fucoxanthin were found to be major carotenoids in both Anisoptera and Zygoptera. These carotenoids were assumed to have originated from aquatic insects, water fleas, tadpoles, and small fish, which dragonfly larvae feed o...

Horse chestnut (Aesculus hippocastanum L.) seed fatty acids, flavonoids and heavy metals plasticity to different urban environments
In this study, the content of fatty acids, flavonoids, aescin and heavy metals in seeds of 11 horse chestnut genotypes growing in urban conditions was investigated. A total of 16 fatty acids were identified. Unsaturated fatty acids in seed samples were the most abundat. Among the saturated fatty acids, palmitic acid was the dominant one, with a total average content of 8.12%. Oleic acid, with the total average content of 53.46%, was the most abundant unsaturated fatty acid. The results of this study indicated the presence of the following flavonoids: quercetin, kaempferol and rutin. Rutin was the most abundant, averagely c...
