Hawthorn (Crataegus spp. L.) is a native fruit of great economic importance in Turkey and has been widely using in folk medicine particularly for the treatment of mild heart diseases for a long time. In the study, 18 previously selected hawthorn genotypes belong to several Crataegus species grown in the hawthorn repository collection in Malatya province in Turkey were evaluated. Fruit mass and ...

Ecological speciation with gene flow may be an important mode of diversification for phytophagous insects. The recent shift of Rhagoletis pomonella from its native host downy hawthorn (Crataegus mollis) to introduced apple (Malus domestica) in the northeastern United States is a classic example of sympatric host race formation. Here, we test whether R. pomonella has similarly formed host races ...

Antrodia cinnamomea is a valuable fungus. The 4-acetylantroquinonol B (4-AAQB) contained in it has strong anticancer activity. In this study, five kinds of herbs, burdock, wolfberry, coix seed, hawthorn, and tangerine peel were selected processed into powders, aqueous extracts, ethanolic extracts to investigate the effects on production 4-AAQB by A. cinnamomea. A combination strategy was conduc...

To investigate the possibility that natural medicines affect lipid metabolism by regulating lipoprotein lipase (LPL) expression, a green fluorescent protein (GFP) gene was constructed downstream of the peroxisome proliferator response element (PPRE) and the constructed plasmid was microinjected into Xenopus oocytes to establish a PPRE regulatory reporter system. Using this system, hawthorn flav...

Seasonal distributions of the western cherry fruit fly, Rhagoletis indifferens Curran (Diptera: Tephritidae), in sweet cherry (Prunus avium (L.) L.) (major host), black hawthorn (occasional developmental host) (Crataegus douglasii Lindley), and other trees were determined in a ponderosa pine ecosystem in Washington state, USA. The hypothesis that most fly dispersal from cherry trees occurs afte...

In the preceding study (Feder et al., 1990), we report that paired apple and hawthorn infesting populations of Rhagoletis pomonella are genetically differentiated for six allozymes. Here, we show that patterns of intra- and inter-host allele frequency variation seen for these six loci across the eastern United States are consistent on a more fine grained spatial scale in western Michigan. Malic...

The experiment was conducted to proof the new natural plant extracts (Fagopyrum Mill. (buckwheat), Crataegus ex L., (hawthorn), Hypericum L. (St -John's -wort's) and Helichrysum arenarium) and selected flavonoids as reference substances for the in vitro. The probing was performed as considering four different parameters: the antioxidant activity, the antiradical activity – DPPH test, the DPH te...
