The aim of this study was to isolate pectins with antioxidant activity from the leaves of Epilobium angustifolium L. Two pectins, EA-4.0 and EA-0.8, with galacturonic acid contents of 88 and 91% were isolated from the leaves of E. angustifolium L. by the treatment of plant raw materials with aqueous hydrochloric acid at pH 4.0 and 0.8, respectively. EA-4.0 and EA-0.8 were found to scavenge the DPPH radical in a concentration-dependent manner at 17–133 μg/mL, whereas commercial apple pectin scavenged at 0.5–2 mg/mL. The antioxidant activity of EA-4.0 was the highest and exceeded the activity of EA-0.8 and a commercial apple pectin by 2 and 39 times (IC50—0.050, 0.109 and 1.961 mg/mL), respectively. Pectins EA-4.0 and EA-0.8 were found to possess superoxide radical scavenging activity, with IC50s equal to 0.27 and 0.97 mg/mL, respectively. Correlation analysis of the composition and activity of 32 polysaccharide fractions obtained by enzyme hydrolysis and anionic exchange chromatography revealed that the antioxidant capacity of fireweed pectins is mainly due to phenolics and is partially associated with xylogalacturonan chains. The data obtained demonstrate that pectic polysaccharides appeared to be bioactive components of fireweed leaves with high antioxidant activity, which depend on pH at their extraction.

“…13 Thereby, the industry is searching for sources of natural LMP such as sunflower heads, which are available in copious amounts as remainders from seed collection. 14,15 Although sucrose is not required for the gelation of LMP, low contents (10-20%) improve the flavour and taste. 16 Currently, in order to reduce the glycemic index, there is a notable trend towards the consumption of low-calorie alternatives to sucrose such as stevia and saccharin, which are at least 400 times sweeter in taste.…”

BACKGROUND: This study reports the use of low glycemic sunflower pectin gel, elaborated with calcium and without or with sweeteners (sucrose, stevia and saccharin) as an edible coating and its possible combination with two modified atmosphere packaging (MAP), in order to extend shelf life, maintaining the quality, of strawberries during the storage at 4°C. RESULTS: This pectin coating, formed with only calcium and/or stevia or saccharin, extended the shelf life of strawberries with respect to uncoating fruits, up to 12 days, keeping the microbial load constant, the firmness and less weight loss. With the same edible coatings, the shelf life of strawberries was extended up to 23 days when they were combined with MAP [10% carbon dioxide (CO 2 ), 85% nitrogen (N 2 ) and 5% oxygen (O 2 )], maintaining the quality of strawberries, while the other MAP, with a higher CO 2 concentration (20% CO 2 , 75% N 2 and 5% O 2 ), had no effect.CONCLUSIONS: These results highlight the suitability of the combination of edible pectin coating combined with MAP to obtain an important shelf life extension, maintaining the good quality of the fruit.

“…Nine of them are publications from 2015 to 2017 from which it can be concluded that interest and research on the valuable composition of hogweed is increasing. A large proportion is devoted to research on the production of food and agricultural feed from the hogweed [6], [9], [13], [17]- [19], [23], [39], emphasizing the acquisition of polysaccharides from the hogweed. The plant has great potential in the pharmaceutical industry [13], [16]- [18], [21], [23].…”

“…From seeds and fruit shells it is possible to obtain furanocoumarinan organic chemical compound derived from plantsangelicin, which can be used in pharmacy [21]. Pectin from the trunk, leaves and stalks can be used as a thickener in food, for example, as gelatin [19]. A variety of extracts can be obtained from the surface of the plant which in general, Heracleum L. genus contains with characteristics of antimicrobial, antipyretic, immune stimulant, analgesic and vasodilator properties and can be used for enzymes and psoriasis [18].…”

Multicriteria analysis methodology used in the paper allows to evaluate the use of potential bioresources with high added value by prioritizing products from invasive species. The method is applied for the hogweed Heracleum sosnowskyi Manden, which occupies large areas in Latvia and poses great problems in using agricultural land. It is combated purposefully, generating significant amount of biomass waste. The results of TOPSIS multicriteria analysis used with 14 indicators, show that hogweed can be used for production of different pharmaceutical, food, soil fertilizer and chemical materials with a high added value. Pharmaceutical products have the highest potential for production of polysaccharides that can be used in food and pharmaceutical industries.
