Summary
Rosehip varieties cultivated in Samara exhibit significant antioxidant properties, including high levels of phenols and flavonoids. These findings support their recommendation for widespread cultivation in the region due to their potent biological activity.
Area of Science:
- Agricultural Science
- Phytochemistry
- Food Science
Background:
- Rosehips (Rosa spp.) are rich in bioactive compounds, contributing to their antioxidant effects.
- Varietal differences in rosehip composition can influence their overall biological activity and potential applications.
Purpose of the Study:
- To evaluate the antioxidant activity of diverse rosehip varieties from the Scientific Research Institute «Zhigulevskiye Sady» collection.
- To assess the suitability of these rosehip varieties for cultivation in the Samara region based on their phytochemical profiles.
Main Methods:
- Analysis of antioxidant activity using antiradical capacity and Ferric Reducing Antioxidant Power (FRAP) assays.
- Quantification of total phenols, total flavonoids, anthocyanins, vitamin C, organic acids, reducing sugars, and soluble solids.
- Evaluation of antioxidant activity in a linoleic acid system.
Main Results:
- Varieties Samarskiy Yubileyniy, Samarskiy, and Desertniy showed the highest total phenol content.
- Desertnyi and Rosa spinosissima L. exhibited the highest total flavonoid content; Rosa spinosissima L. also contained anthocyanins.
- Desertnyi demonstrated superior antiradical activity and Ferric Reducing Antioxidant Power (FRAP), while all varieties inhibited linoleic acid oxidation.
Conclusions:
- The studied rosehip varieties possess high antioxidant activity and rich phytochemical profiles.
- Specific varieties, such as Desertnyi, show exceptional antioxidant potential.

The energy stored by a structure and location of matter in space is called potential energy. For instance, raising a kettlebell changes its spatial location and increases its potential energy. Similarly, a stretched rubber band contains potential energy which, under certain conditions, can be converted into other forms of energy, such as kinetic energy.
Chemical bonds that form attractive forces between atoms also contain potential energy, called chemical energy. When a chemical reaction...

A conservative force, such as a gravitational or elastic force, gives the body the capacity to do work. This capacity, measured as the potential energy, depends on the body's location or “position” relative to a fixed reference position or datum. The gravitational potential energy is considered zero at the reference point. Suppose a body is located at some vertical distance above a fixed horizontal reference or datum. In that case, the weight of the body has positive gravitational potential...

On comparing the reactivity of silver and lead, it is observed that the two ionic species, Ag+ (aq) and Pb2+ (aq), show a difference in their redox reactivity towards copper: the silver ion undergoes spontaneous reduction, while the lead ion does not. This relative redox activity can be easily quantified in electrochemical cells by a property called cell potential. This property is commonly known as cell voltage in electrochemistry, and it is a measure of the energy which accompanies the charge...

Thermodynamics of a Redox Reaction
Thermodynamics is the branch of physics dealing with the relationship between heat and other forms of energy. In an electrochemical cell, chemical energy is converted into electrical energy.
Thus, a link can be predicted between cell potential, free energy change, and the equilibrium constant for the reaction. Cell potential can also be measured as the oxidant or the reducing strength, and similar acid-base strength measures are reflected in equilibrium...

Suppose a positive test charge moves away from a positive static charge, then the Coulomb force does positive work, and its electric potential energy decreases. The potential energy per unit charge is defined as the electric potential. The electric potential is independent of the test charge.
When a test charge moves from the initial to the final position, the electric potential difference between those positions is defined as the ratio of the change in the potential energy to the charge on the...
