The purpose of this research is to know the class of compounds, profiling IC 50, LC 50 and the Selectivity Index of root extracts, stems, seeds and leaves of sunflower plants (Helianthus annuus). Helianthus is likely to be regarded as a difficult genus by many, careful study of the excellent key provided by Voss ( 996), which typically provides many alternative characters, should enable one to make reliable identifications. The aim of this study was to evaluate the differences in the antioxidant activity and phenolic profile of sunflower (Helianthus annuus L.) extracts obtained from the aerial parts of plants harvested at five growth stages. It is found in shallow water rocky habitats and in the kelp forests off the Pacific coast of Ecuador, Peru and Chile. The soil is an eutric Cambisol, sandy loam textured, with 10 g kg-1 of organic matter and pH (H 2 O) 5.8. Although Heliaster is distributed at present only on parts of the eastern Pacific shoreline, fossils of Heliaster were found in the Pliocene of Florida (Jones & Portell 1988).

Schilling (2006) has provided a detailed taxonomic overview of the Helianthus praecox complex, treating this as comprised of three infraspecific categories: subsp.
Sunflowers are native primarily to North and South America, and some species are cultivated as ornamentals for their spectacular size and flower heads. Subspecies debilis hybridization with subspecies vestitus may cause the latter to go extinct. The fractions of protein from Helianthus tuberosus tubers with inulinase activity, immobilized on ion-exchange KU-2 pitch, were objects of research (activity of heterogeneous preparation was ~ 80%). It is also cultivated widely across the temperate zone for its tuber, which is used as a root vegetable. This species is present in the southeastern Pacific Ocean, along the west coast of South America. This sunflower species is also used as bird food, as livestock forage (as a meal or a silage plant), and in some industrial applications. The isocentric arm reduces examination time by allowing all breast projections to be made without having to adjust the height of the C-arm or move the patient. across (20-30 cm), with brilliant golden-yellow petals surrounding a dark chocolate central disk.

Extensive hybridizing has resulted in a great number of cultivars providing a wide range of colors (yellow, red, orange, creamy-white and bicolor), flower shapes (short or long rays, frilled or double), and sizes (dwarf to giant).

Despite their common occurrence and critical ecological role, little is known about how these generalist predators respond to variation in prey productivity over geographic scales. This accounts for its extensive spread outside its native east coast range and up and down the west coast of Florida. Sunflower (Helianthus annuus L.) is one of the few crop species that originated in North America (most originated in the Fertile Crescent, Asia or South or Central America).

The Helianthus front attachment for sunflower harvesting adopts a row-independent harvesting system. The growing demand of the Russian population for healthy food dictates the need in functional ingredients production increase. Soil types include sand, chalk and loam within an alkaline or neutral PH balance. The rates and patterns of feeding and displacement of predators constitute two of the most important plastic behavioral responses that allow individuals to respond quickly to changes in abundance of their prey, predation risks and to rapid alterations in environmental conditions.
