This study aimed to characterise pressurised hot water (PHW) extracts from nonconventional sources of functional carbohydrates and phenolic compounds in terms antioxidant capacity, antiviral activity, toxicity, human erythrocytes' protection antidiabetic potential. PHW Norway spruce bark (E1 + E2) Birch sawdust (E3 E4) contained mostly galactoglucomannan glucuronoxylan. In contrast, samples E5 E9 extracted spruce, Scots pine are rich compounds. Overall, phenolic-rich presented the highest...
Aqueous extracts from blackcurrant press cake (BC), Norway spruce bark (NS), Scots pine (SP), and sea buckthorn leaves (SB) were obtained using maceration pressurized hot water tested for their bioactivities. Maceration provided the extraction of higher dry matter contents, including total phenolics (TPC), anthocyanins, condensed tannins, which also impacted antioxidant activity. NS SB presented highest mean values TPC Individually, extract high contents proanthocyanidins, resveratrol, some...
This study demonstrated the antibacterial and antiviral potential of condensed tannins tannic acid when incorporated into fiber networks tested for functional material purposes. Condensed were extracted from industrial bark Norway spruce by using pressurized hot water extraction (PHWE), followed purification extracts XADHP7 treatment to obtain sugar-free extract. The chemical composition was analyzed HPLC, GC‒MS UHPLC after thiolytic degradation. test matrices, i.e., lignocellulosic...
Earlier studies have shown that the bark of Salix L. species (Salicaceae family) is rich in extractives, such as diverse bioactive phenolic compounds. However, we lack knowledge on properties willow and clones adapted to harsh climate conditions cool temperate zone. Therefore, present study aimed obtain information functional profiles northern for use value-added solutions. Of 16 studied here, 12 were examples widely distributed native Finnish species, including dark-leaved (S. myrsinifolia...
Due to seasonally appearing viruses and several outbreaks present pandemic, we are surrounded by in our everyday life. In order reduce viral transmission, functionalized surfaces that inactivate large demand. Here the endeavor was functionalize cellulose-based materials with tannic acid (TA) tannin-rich extracts using different binding polymers prevent infectivity of both non-enveloped coxsackievirus B3 (CVB3) enveloped human coronavirus OC43 (HCoV-OC43). Direct antiviral efficacy TA spruce...
To efficiently lower virus infectivity and combat epidemics or pandemics, it is important to discover broadly acting antivirals. Here, we investigated two naturally occurring polyphenols, Epigallocatechin gallate (EGCG) Resveratrol (RES), polyphenol-functionalized nanoparticles for their antiviral efficacy. Concentrations in the low micromolar range permanently inhibited of high doses enteroviruses (107 PFU/mL). Sucrose gradient separation radiolabeled viruses, dynamic light scattering,...
L. is a carnivorous plant used in traditional medicine for its therapeutic properties. Because of small size, collection nature laborious and different cultivation methods have been studied to ensure availability. However, only few studies exist where the lab-grown sundew tissue field-grown would compared their functionality or metabolic profiles. In this study, antioxidant antiviral activities extracts profiles are examined. The effect drying on chromatographic profile also shown....
Recurring viral outbreaks have a significant negative impact on society. This creates need to develop novel strategies complement the existing antiviral approaches. There is for safe and sustainable solutions derived from nature. study aimed investigate potential of willow (Salix spp.) bark hot water extracts against coronaviruses enteroviruses. Willow has long been recognized its medicinal properties used in traditional medicines. However, as broad-spectrum agent remains relatively...
