“…). Astringin as well as piceid and isorhapontin belong to the stilbene glucoside family, which has been intensively studied and reported to be abundant in spruce bark (Mannila and Talvitie, ; Pan and Lundgren, ; Kylliainen and Holmbom, ) and they all exhibit antioxidant activity (Wang et al , ). Furthermore, the obtained mass spectra (see Figs.…”

“…Compound 1, obtained as colorless amorphous powder, was identified as piceatannol, one of the stilbenes widespread in plants, such as Picea sp., 10) grapes, 11) rhubarb 12) and others, based on the various spectral data. Compound 2, isolated as a dark brownish amorphous powder, was concluded to be scirpusin B, a constituent of Scirpus fluviatilis, based on comparison of the various spectral data with those in the literature.…”

From stem bark of Callistemon rigidus (Myrtaceae), piceatannol and scirpusin B were isolated as components that exhibit inhibitory effects on a a -amylase activity in isolated mouse plasma. In particular, scirpusin B also inhibited a a -amylase in mouse gastrointestinal tract. Thus, we expect the depressive effect on the elevation of postprandial blood glucose may be a new medicinal use of this compound as well as the plant itself.

“…Dehydroabietic acid is the main component of the abietane diterpene content with a plethora of bibliographic references regarding its antibacterial and antifungal properties [4]. On the other hand, several phenolic compounds including stilbenes, lignans, flavonoids, and tannins have been referred in hydrophilic bark extracts [5,6]. These compounds are of high interest, with numerous biological properties and applications in food and pharmaceutical industry [7].…”

Bio-Guided Isolation of Methanol-Soluble Metabolites of Common Spruce (Picea abies) Bark by-Products and Investigation of Their Dermo-Cosmetic Properties

Abstract:Common spruce (Picea abies L.) is a fast-growing coniferous tree, widely used in several countries for the production of sawn wood, timber and pulp. During this industrial exploitation, large quantities of barks are generated as waste materials. The aim of this study was the bio-guided investigation and the effective recovery of methanol-soluble metabolites of common spruce bark for the development of new dermo-cosmetic agents. The active methanol extract was initially fractionated by Centrifugal Partition Chromatography (CPC) using a triphasic solvent system in a step-gradient elution mode. All resulting fractions were evaluated for their antibacterial activity, antioxidant activity and their capability to inhibit tyrosinase, elastase and collagenase activity. In parallel, the chemical composition of each fraction was established by combining a 13 C-NMR dereplication approach and 2D-NMR analyses. As a result, fourteen secondary metabolites corresponding to stilbene, flavonoid and phenolic acid derivatives were directly identified in the CPC fractions. A high amount (0.93 g) of E-astringin was recovered from 3 g of crude extract in a single 125 min run. E-Astringin significantly induced the tyrosinase activity while E-piceid, taxifolin, and taxifolin-3 -O-glucopyranoside exhibited significant anti-tyrosinase activity. The above compounds showed important anti-collagenase and antimicrobial activities, thus providing new perspectives for potential applications as cosmetic ingredients.
