Dispersive liquid-liquid microextraction method (DLLME) combined with high-performance liquid chromatography-ultraviolet detection (HPLC-UV) was used to determine thiamine (B1), nicotinamide (B3) and pyridoxine (B6) in sour cherry juice. This method was rapid, simple and sensitive. Separation was accomplished using a C18 column. The optimum chromatographic conditions were found to be: mobile ph...

The present study was carried out to determine variations in flower and dye yield chemical contents of safflower genotypes with different colors 2017–2018. dyestuff yields the genotype ranged between 6.6–12.0 kg da−1 218.1–421.7 g da−1, respectively. TPC high antioxidant capacity values were listed according color as yellow > orange red white. Gallic, rosmarinic chlorogenic acid higher orang...

Eight African marigold varieties (`Nari `(orange), `Bindi`(orange), `Bali` (orange), `Little Duck `(orange), `Bali` (yellow), `Bali` (gold), `Little Duck` (yellow) and `Eagle` (yellow) were comparatively studies for growth habit and flowering quality in open field condition at Training Centre for Floriculture and Landscaping, Directorate of Floriculture, Lahore during 2018-2019. Among the varie...

Hummingbird flowers are typically red in color but the reasons for this are not well understood. Relatively few studies have examined hummingbird flower color preferences under natural conditions in which flower color varies within a species. We recorded hummingbird visitation rates to flowers that vary in color from yellow to red in a natural hybrid population between redand yellow-flowered Mi...

Lutein is a health promoting xanthophyll that may be extracted from marigold flowers. But the plant is known also for biosynthesis of phototoxic polythiophenes. Extracts of flowers of some Tagetes species grown in Belgorod (RF) T. erecta L. (cv. Gavaii) , T. patula L. (cv. Petit orange), T. tenuifolia Cav. (unknown cv.), and T. lucida Cav. were investigated by thin layer chromatography (TLC) an...

ABSTRACT In breeding programs, the identification of genetic variability and knowledge constitutions existing within segregating populations are fundamental importance for success continuation program. The present study aimed to quantify diversity among progenies a sour passion fruit population based on morphoagronomic variables flowers fruits using Ward-MLM (modified location model) procedure,...
