“…7α,15-Dihydroxydehydroabietic acid was present as a minor compound in Fr.III and Fr.IV. This abietane diterpene has been previously identified in the aerial parts of Abies georgei Orr [16] and buds of Pinus banksiana Lamb together with its 7β-isomer, [17] while its 4-epi-isomer has been referred in stems of Illicium jiadifengpi [18] and air-dried fruits of Juniperus polycarpus var. seravschanica [19].…”

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.

“…Naturally occurring oplopanane sesquiterpenoids are rarely reported [ 16 , 17 ]. Literature searching showed that there were no more than 20 such type sesquiterpenoids reported up to now, distributed among the families of Alismataceae [ 16 , 17 ], Araliaceae [ 18 ], Araceae [ 19 ], Asteraceae [ 20 ], Chloranthaceae [ 21 ], Cyperaceae [ 22 ], Magnoliaceae [ 23 ], Meliaceae [ 24 ], Schisandraceae [ 25 ], Salicaceae [ 26 ], and Zingiberaceae [ 27 ]. In this study, six oplopananes ( 1 – 6 ), including four new ( 1 – 4 ) and one 3,5- seco -oplopanane ( 6 ), were discovered from the rhizomes of H. occulta .…”

Naturally occurring oplopanane sesquiterpenoids are rarely reported. A phytochemical investigation on the rhizomes of Homalomena occulta (Lours) has resulted in the discovery of six oplopanane sesquiterpenoids (1–6), including four new (1–4) and one 3,5-seco-oplopanane (6), together with three previously reported sesquiterpenoids (7−9). In addition three new oplopananes (2a–4a) were also obtained by chemical transformation. All structures of these sesquiterpenoids were established based on the comprehensive spectroscopic analyses, including NMR, MS, and IR, and comparing with the literatures.Graphical AbstractElectronic supplementary materialThe online version of this article (doi:10.1007/s13659-016-0104-8) contains supplementary material, which is available to authorized users.
