Saint John’s worts or goatweeds are mostly perennial flowering plants in the Hypericaceae family, formerly under Clusiaceae family. Teas and macerations of common traditional medicines modern depression cancer therapies. The most notable bioactive compounds Hypericum hyperforin hypericin. While contains a variety carotenoid phenolic compounds, which well documented, there is little available information on tocopherols almost none tocotrienols. Considering frequency tocotrienol derivatives...

Now under Clusiaceae and Hypericaceae, Clusia Hypericum were previously categorized one family until they divided in 2003 by the APG III system. The genus is characterized presence of tocotrienol derivatives with antiangiogenic properties, only perforatum tocochromanol content has been studied genus. Twelve species analyzed: H. aegypticum, calycinum, empetrifolium, lancasteri, olympicum f. minus ‘Sulphureum’, perforatum, xylosteifolium, C. fluminensis, minor, odorata, palmicida, tocuchensis....

Hypericum perforatum L., commonly known as St. John’s wort, is a widely distributed herbaceous plant utilized in traditional and phytomedicinal applications, particularly for its hydrophilic bioactive compounds. It often used treating early depressive states. In this study, we focused on reporting the tocotrienols—lipophilic phytochemicals with health-promoting properties—in wort. H. flowerheads predominantly contained tocotrienols compared tocopherols (54 30 mg/100 g dry weight,...

St. John’s wort (Hypericum perforatum L.) is an ornamental and medical plant, distributed worldwide, which rich in diverse secondary metabolites. The discovery of the presence tocotrienols (rare prenyllipids) H. marks a new chapter demanding deeper understanding accumulation these lipophilic biomolecules. Three wild populations were harvested Latvia at three different locations from 2022 to 2024 separated into stems, leaves, flower buds, flowers. Plant samples freeze-dried, ground,...

St. John's wort (Hypericum perforatum) is a medicinal plant known for its bioactive compounds, including tocopherols and tocotrienols, which possess antioxidant anti-inflammatory properties. These compounds play vital roles in the plant's metabolism have potential applications cosmetic pharmaceutical industries. However, content of these different anatomical parts plant, as well influence environmental factors, such year collection, remain underexplored. This study examined tocochromanols H....

New cold‐pressed oil recovered from seeds of Japanese quince ( Chaenomeles japonica (Thunb.) Lindl. ex Spach, family: Rosaceae), obtained as a by‐product fruit processing, was characterized and compared with nine well‐known oils. The seed had the highest amounts tocopherols, β‐carotene, total phenolic compounds (726.20; 10.77 64.03 mg/kg, respectively) lowest amount chlorophyll (0.12 mg/kg) peroxide value (0.59 mEq O 2 /kg) to sesame, poppy, peanut, flaxseed, pumpkin, sunflower, almond,...

Abstract BACKGROUND The health‐promoting properties of apples are directly related to the biologically active compounds that they contain, such as polyphenols. objective this study was prepare a low‐sugar, fibre‐ and phlorizin‐enriched powder from unripe gain insight regarding its anti‐hyperglycaemic activity in healthy volunteers. RESULTS ( Malus domestica Borkh.) were collected 30 days after full bloom day; blanched pressed obtain apple pomace which then processed with food cutter,...

The profiles of tocopherols and tocotrienols (vitamin E) in the seed oils recovered from apple ( Malus domestica Borkh.), canary melon Cucumis melo L.), gooseberry Ribes uva‐crispa grape Vitis vinifera Japanese quince Chaenomeles japonica ), pomegranate Punica granatum red currant rubrum sea buckthorn Hippophae rhamnoides watermelon Citrullus lanatus ) by‐products fruit industry were studied. highest concentration tocochromanols was found oil (398.73 mg/100 g) lowest (69.13 g). γ α...

The objective of this study was to determine the effects on quality incorporating raspberry and cranberry pomaces into American-style muffins prepared under various baking conditions. different conditions did not affect texture or microstructure control muffins. enhanced samples baked at 140 °C for 30 min were characterized by a harder than distributed protein matrix distorted starch granules, while those 240 15 had moist showed incomplete gelatinization. mean percent recovery ellagic acid,...

St. John’s wort (Hypericum perforatum L.) has been extensively utilized across various traditional medicinal systems, including ancient Greek medicine, Chinese and Islamic medicine. H. is a well-known plant due to the presence of hypericin hyperforin, which are natural antidepressants. Recent studies indicate that inflorescences wild source rare tocotrienols, primarily δ-T3. Similar lacking for cultivated species. was grown three years. At full bloom each year, cut separated into its parts:...

Eight tocochromanols (α, β, γ, and δ homologues of tocopherol tocotrienol) naturally occurring in foods were successfully separated within a 13‐min run the RP‐HPLC mode. Analytes on Phenomenex Luna PFP column filled with pentafluorophenyl stationary phase (3 µm, 150 mm × 4.6 mm) using mobile containing methanol:water (93:7 v/v) an elution flow rate 1 ml/min oven temperature 40°C. The method was rapid, linear, accurate, precise detection limits range 0.000184–0.000605 µg, preventing analyte...

The antioxidant capacity (AC) of boiled-type coffee brews (CB) and phenolic acids (PA) isolated from them, obtained the caffeinated decaffeinated beans different geographical origins species with roasting degrees, was examined. AC PA CB samples tested in five assays: a total antioxidants reducing assay using Folin–Ciocalteu reagent (FCR), ferric ion power (FRAP) assay, DPPH· radical-scavenging activity (DPPH) metal chelating (MCA) radical trapping parameter (TRAP) assay. In most samples,...

Tocochromanols composition in apple seeds, obtained as a by-product during the fruit salad and juice production, of twelve varieties - seven crab ('Kerr', 'Kuku', 'Quaker Beauty', 'Riku', 'Ritika', 'Ruti' K-8/9-24) five dessert apples ('Antej', 'Beforest', 'Kent', 'Sinap Orlovskij' 'Zarja Alatau') were studied. Tocopherols tocotrienols isolated using micro-saponification method high precision accuracy they analysedanalysed by rapid RP-HPLC/FLD RP-UPLC-ESI/MSn. Four tocopherols, with...
