As the interest in heirloom cultivars of apple trees, their fruit, and processed products is growing worldwide, studies of the qualitative and quantitative composition of biological compounds are important for the evaluation of the quality and nutritional properties of the apples. Studies on the variations in the chemical composition of phenolic compounds characterized by a versatile biological effect are important when researching the genetic heritage of the heirloom cultivars in order to increase the cultivation of such cultivars in orchards. A variation in the qualitative and quantitative composition of phenolic compounds was found in apple samples of cultivars included in the Lithuanian collection of genetic resources. By the high-performance liquid chromatography (HPLC) method flavan-3-ols (procyanidin B1, procyanidin B2, procyanidin C2, (+)-catechin and (-)-epicatechin), flavonols (rutin, hyperoside, quercitrin, isoquercitrin, reynoutrin and avicularin), chlorogenic acids and phloridzin were identified and quantified in fruit samples of heirloom apple cultivars grown in Lithuania. The highest sum of the identified phenolic compounds (3.82 ± 0.53 mg/g) was found in apple fruit samples of the 'Koštelė' cultivar.

Background: Kombucha, a fermented beverage obtained from a Symbiotic Culture of Bacteria and Yeast (SCOBY), has shown potential in modulating gut microbiota, although no clinical trials have been done.
Objective: We aimed to evaluate the effects of regular black tea kombucha consumption on intestinal health in individuals with and without obesity.
Methods: A pre-post clinical intervention study was conducted lasting eight weeks.

This study investigated the antihyperglycemic potential of a hydroalcoholic extract from Syzygium malaccense leaves (E-SM) and isolate phenolic compounds with antioxidant and cytotoxic activities through a bioguided assay. The aim was to explore the therapeutic properties of S. malaccense in managing hyperglycemia and oxidative stress-related conditions.

Black rice bran (BRB), a valuable byproduct from the rice milling process, possesses numerous pharmacological activities, including antioxidant potential, but information regarding highly efficient extraction methods is scarce. To enhance the extraction efficiency, ultrasonic-assisted extraction coupled with Box-Behnken design (BBD) was used in this study to maximize the total phenolic content (TPC), total flavonoid content (TFC), total anthocyanin content (TAC), and antioxidant capacity of BRB extract. The BBD results showed that 57% ethanol at 50°C and pH 3.

This study aimed to examine the extraction of specific phenolic compounds from blackthorn using ultrasound-assisted extraction (UAE) and to evaluate the influence of UAE on the phenolic composition, bioaccessibility, and cytotoxic effect evaluated on ovarian cancer (OVCAR-3 and SKOV-3) and healthy (HaCaT) cell lines. The UAE parameters were optimized by modeling with the response surface method. Temperature, time, and ultrasound amplitude were utilized to determine the optimal extraction conditions.
