Sea buckthorn ( Hippophae rhamnoides L.), a wild berry abundant in Georgia, is a rich source of bioactive compounds, including antioxidants, fatty acids, and phenolic compounds, with significant potential for applications in food, nutraceutical, and cosmetic industries. Despite its traditional uses, the physicochemical properties and valorization potential of Georgian sea buckthorn remain underexplored. This study aimed to analyze the chemical composition of sea buckthorn berries from three distinct regions of Georgia (Adjara, Samtskhe‐Javakheti, and Imereti) and develop innovative, environmentally friendly extraction technologies to maximize the recovery of valuable compounds. Using advanced techniques such as ultrasound‐assisted extraction (UAE) and supercritical water extraction (SWE), alongside traditional methods like maceration and Soxhlet extraction, the study identified and quantified 18 bioactive compounds, including organic acids (malic and citric acid), phenolic acids (quinic acid), and flavonoids (e.g., gallocatechin, catechin, and isorhamnetin derivatives). The lipid fraction, predominantly composed of C18 fatty acids (57.4%–76.9%), was rich in linoleic acid (29.4%–50.0%), with extraction yields varying by method. Total phenolic content ranged from 19.90 to 34.94 mg/g dry weight, with higher levels in Samtskhe‐Javakheti and Imereti samples. The highest carotenoid content (3.363 mg/g dry weight) was observed in Samtskhe‐Javakheti berries. UAE with 75% ethanol optimized carotenoid (1.684 mg/g) and phenolic (8.213 mg/g) recovery, while SWE achieved 86% lipid yield and high phenolic content (92.25 mg/g) in just 7 min. Carotenoid‐enriched sunflower oil exhibited 3.5‐fold higher antioxidant activity than control oil, demonstrating enhanced oxidative stability. The study highlights the efficacy of green extraction methods in valorizing sea buckthorn by‐products, offering sustainable solutions for producing high‐value nutraceuticals and functional foods. These findings underscore the potential of Georgian sea buckthorn as a source of natural antioxidants and lipids, with applications in health‐promoting products.

The study determined the content of lycopene in the fruits of the Elaeagnus umbellata (35.25–60.21 mg/100 g), common at different heights above sea level in Western Georgia. For the effective extraction of lycopene as a biologically active substance, the optimal conditions for ultrasonic extraction were selected: sunflower oil was used as a “green solvent”; the ratio of solid mass and solvent was 1:50; temperature 30°C; ultrasound amplitude 40%; power 85 W; and extraction time 10 min. FTIR spectra revealed the characteristic functional groups of lycopene exhibiting two characteristic peaks at 2920 and 2950 cm⁻¹. To explore the effect of lycopene on oil quality, the acid value, peroxide value, and p‐anisidine were determined in each oil sample. The antioxidant determination by inhibition of DPPH radicals showed significant differences in native oils and oils with lycopene.

The purpose of this research article was to study the physicochemical characteristics of semi-wild Jara honey grown in Western Georgia. Jara honey is produced in the alpine and sub-alpine forest zone of high mountain Adjara, which is distinguished by its variety of honey plants. The physicochemical characteristics were examined concerning the Alimemtarius Code and EU regulations: moisture content, total carbohydrates, free acidity, pH, electrical conductivity, microelements (Li, Na, K, Mg, Ca), color, total phenols, total phenolic acids, total flavonoids, proline, diastase activity, proteins, and microscopic study of pollens. Using the UPLC-MSB method, grayanotoxin-III was identified in the semi-wild Jara honey samples. The findings demonstrated that the honey has significant concentrations of phenols, phenolic acids, and flavonoids. A directly proportional relationship was established between the quantitative content of phenolic compounds and the antioxidant activity of honey. This article is the first study of the characteristics of Jara honey produced in Western Georgia.

Khechechuri is an endemic species of a pear spread over one region of Western Georgia, called Adjara. Pears are a dietary source of bioactive components such as polyphenols and triterpenic acid. In addition to highlighting its gastronomic value, the aim of the article was to examine and compare phenolic compounds, flavonoids, catechins, phenolic acids, and antioxidant activities in Khechechuri collected from various villages in the Adjara region, namely Adjaristskali, Merisi, Dandalo, Shuakhevi, and Khulo. Five parts of the fruit, the skin, edible pulp, whole pear (skin + pulp), juice, and pomace, were analyzed and the results compared. Our study indicated that the highest total phenolic content was found in the skin of West Georgian pear types (4650 mg/kg.) Moreover, the pomace showed significant amounts of total phenolic content in each of the Khechechuri samples analyzed. Flavonoids were found in each part of the Khechechuri pears, with the notable exception of the fruit juice. A positive correlation between the total phenolic content and the geographical altitude of where the fruits were collected was observed.

The purpose of this research article was to study the physicochemical characteristics of semi-wild Jhar honey grown in Western Georgia. Jara honey is produced in the alpine and sub-alpine forest zone of high mountain Adjara, which is distinguished by the variety of honey plants [1]. The physicochemical characteristics were examined concerning the Alimemtarius Code and EU regulations: moisture content, total carbohydrate, free acidity, pH , electrical conductivity, microelements (Li, Na, K, Mg, Ca), color, total phenols, total phenolic acids, total flavonoids, proline, diastase activity, protein and microscopic study of pollens. Using the UPLC-MSB method, grayanotoxin-III was identified in the semi-wild Jara honey samples. The findings demonstrated that honey has significant concentrations of phenols, phenolic acids, and flavonoids. A directly proportional relationship was established between the quantitative content of phenolic compounds and the antioxidant activity of honey. This article is the first study of the characteristics of Jara honey produced in Western Georgia.

The present study was conducted to determine the content of four mineral elements in honeys originating from different regions of West Georgia. Sodium (Na), Potassium (K), Calcium (Ca), magnesium (Mg), and Ammonium (NH4+) were analyzed by HPLC-Conductivity, column “Cation” (3.9x150mm) solvent 0.1 mM EDTA 3mM HNO_3, following the microwave digestion of the honey. High mineral contents were observed in the investigated honeys with K, Na, Ca and Mg being the most abundant elements with mean concentrations in Chestnut honey 5000-7000 ppm, 56-150 ppm, 40-230 ppm, 25-130 ppm, respectively.
