Metal accumulation and biochemical variations in the freshwater mussels (Unio mancus) collected from Atat ürk Dam Lake, Turkey
In this study, we aimed to determine the toxic effects of metals on mussels (Unio mancus) selected as biomonitor organisms in the Atatürk Dam Lake. The effect of metal pollution was evaluated using some biochemical markers [glutathione-S-transferase (GST), acetylcolinesterase (AChE), carboxylesterase (CaE), glutathione reductase (GR), metallothionein (MT)] in the digestive gland of the mussels. Mussels were collected from four sampling sites of dam lake in the winter and summer of 2016. The metal levels in the mussel samples varied significantly across the sites and seasons (p < 0.05).

In the present study, we investigated the fatty acid (FA) compositions in the muscles of Dai-qu stock and Min-yuedong stock large yellow croakers using gas chromatography-mass spectrometry (GC-MS). The results showed that the contents of some FAs were quite different between these two populations. Therefore, the FA composition could be used as a potential indicator for the id...

Dynamic distribution of Aphis gossypii Glover (Homoptera: Aphididae) and incidence of viral disease in different zucchini (Cucurbita pepo L.) cultivars
In conclusion, the ability to resist aphids was not consistent with the ability to resist disease in zucchini. Varieties with a slow transformation rate and mild disease phenotype in the late growth stage had strong ability to resist disease. (Source: Biochemical Systematics and Ecology)

Anatomy, histochemistry, and comparative analysis of hydroxycinnamic derivatives in healthy leaves and galls induced by Baccharopelma spp. (Hemiptera: Psyllidae) in Baccharis spicata (Lam) Baill (Asteraceae)
Publication date: April 2018 Source:Biochemical Systematics and Ecology, Volume 77 Author(s): Ignacio Agudelo, Laura Cogoi, Rosana Filip, Nicolás Kuzmanich, Marcelo L. Wagner, Rafael A. Ricco Baccharis spicata is a plant native to the south of South America And is infected by psyllids of the Baccharopelma genus, which induce a fold gall in its leaves. This infection induces a series of anatomical and phytochemical variations compared to the healthy leaf: the content of total phenolic compounds and total hidroxycinnamic derivatives is lower, though the chlorogenic acid measured by HPLC remains the same and the 4,5 d...

Soyisoflavone diversity in wild soybeans (Glycine soja Sieb. & amp; Zucc.) from the main centres of diversity
Publication date: April 2018 Source:Biochemical Systematics and Ecology, Volume 77 Author(s): Muhammad Amjad Nawaz, Kirill S. Golokhvast, Hafiz Mamoon Rehman, Chigen Tsukamoto, Hong-Sig Kim, Seung Hwan Yang, Gyuhwa Chung Wild soybeans are naturally found in China, and the Korean Peninsula, Japanese archipelago and Russian Far East, which are considered their centres of diversity. The presence of higher amounts of secondary metabolites in wild soybeans makes them the ideal choice to increase soyisoflavone content in cultivated soybeans through modern breeding and biotechnological techniques. Such a superiority calls for so...

Variation of phenolic constituents of Tunisian Thymus capitatus (L.) Hoff. et Link. populations
Publication date: April 2018 Source:Biochemical Systematics and Ecology, Volume 77 Author(s): Rym Jaouadi, Susana M. Cardoso, Artur M.S. Silva, Imen Ben Hadj Yahia, Mohamed Boussaid, Yosr Zaouali Nine Tunisian Thymus capitatus (L.) Hoff. et Link. populations harvested in six bioclimatic zones extending from the sub humid (550 mm rainfall/year) to the lower arid (96.3 mm rainfall/year), and grown at altitudes ranging from 60 to 600 m were assessed for their phenolic composition. The identification of phenolic compounds was revealed by UHPLC-DAD-ESI/MSn. 11 phenolic compounds including three phenolic acids (rosmarinic...

Isoquinoline alkaloids from three Madagascan Crinum (Amaryllidaceae) species
Publication date: April 2018 Source:Biochemical Systematics and Ecology, Volume 77 Author(s): Areej H.S. Aldhaher, Moses K. Langat, Walter Knirsch, Jacky L. Andriantiana, Dulcie A. Mulholland The phytochemistry of two Madagascan Crinum species, Crinum hardyi Lehmiller and Crinum pronkii Lehmiller were investigated and compared to that of Crinum firmifolium Baker which has been investigated previously. In addition to hippadine, lycorine, hippeastrine, masonine and crinine from C. firmifolium, lycorine, crinine, and 6-hydroxycrinamine from Crinum hardyi and lycorine, 6-hydroxycrinamine and pseudolycorine from C. p...

Chemical constituents from Tsuga longibracteata and its chemotaxonomic study
Publication date: April 2018 Source:Biochemical Systematics and Ecology, Volume 77 Author(s): Guiyuan Liu, Qinfeng Nie, Qinghua Weng, Maosheng Zhang, Lisheng Ding, Yan Zhou, Fang Chen, Shiji Xiao Phytochemical investigation into the bark of Tsuga longibracteata led to the isolation of three lignans (1–3), two triterpenoids (4, 5), nine flavonoids (6−14), three sterols (15–17) and five phenolic acids (18–22). Their structures were determined by spectroscopic analysis of their spectral data with those reported in literature. Among them, compounds 1–3, 6–22 were obtained from this species ...

Phytochemical and chemotaxonomic study of Polygala altomontana (Polygalaceae)
In this study, 7 compounds were isolated from a hydroalcoholic extract of Polygala altomontana: aurapten (1), α-spinasterol (2) dihydrostyryl-2-pyrone (3) and styryl-2-pyrones (4–7). The styryl-2-pyrone (5) is new in the literature and although the others are known compounds this is the first time they have been isolated from the species P. altomontana. This is the second species of the genus Polygala to present the accumulation of dihydrostyryl-2-pyrones and styryl-2-pyrones. The chemotaxonomic significance of this data for the Polygala genus was summarized. (Source: Biochemical Systematics and Ecology)

Biochemical changes in terminal buds of three different walnut (Juglans regia L.) genotypes during dormancy break
In this study biochemical changes in terminal buds of three different walnut genotypes (early-season, mid-season, and late-season), was investigated during winter dormancy release time. Terminal bud samples were taken from the genotypes in two different times in winter (1st and 20th of March). Variables such as; bud soluble sugars, starch, proline, chlorophyll, total phenolic and protein content as well as catalase (CAT) and guaiacol peroxidase (GPO) enzymes activities were assessed. Analysis of variance ANOVA) revealed significant differences (p ≤ 0.05) for the measured variables and sampling times among the ...

Rapid identification of Fritillariae Cirrhosae Bulbus and its adulterants by UPLC-ELSD fingerprint combined with chemometrics methods
In this study, a UPLC-ELSD fingerprint analysis with chemometric methods, including similarity analysis, hierarchical clustering analysis, and principal component analysis, were applied for the identification of FCB and its adulterants. Our results indicated that the combined method could efficiently identify and distinguish FCB from its adulterations. The proposed method provides a potential perspective for the quality control of traditional Chinese medicine. (Source: Biochemical Systematics and Ecology)
