TLDR
In this paper, two soluble phenolics have been isolated from Norway spruce needles and their structures elucidated on the basis of chromatographic (TLC, HPLC), chemical (hydrolysis), enzymic and spectroscopic (UV, NMR, MS) techniques.About:

Antioxidant activity of plant extracts containing phenolic compounds
Marja P Kähkönen,Anu Hopia,Heikki Vuorela,Jussi-Pekka Rauha,Kalevi Pihlaja,Tytti S. Kujala,Marina Heinonen +6 more
TL;DR: High activities were found in tree materials, especially in willow bark, spruce needles, pine bark and cork, and birch phloem, and in some medicinal plants including heather, bog-rosemary, willow herb, and meadowsweet and potato peel and beetroot peel extracts showed strong antioxidant effects.
Journal ArticleDOI
Anthocyanins and other flavonoids
TL;DR: More than 450 new flavonoid structures, reported from January 2001 until December 2003, are reviewed and the biological activity of some of the compounds is discussed.
Journal ArticleDOI
Apoplastic Peroxidases and Lignification in Needles of Norway Spruce (Picea abies L.).
TL;DR: It is suggested that soluble alkaline apoplastic peroxidases participate in lignin formation in spruce needles, which was apparently unrelated to developmentally regulated lignification inspruce needles.
Journal ArticleDOI
Contents of soluble, cell-wall-bound and exuded phlorotannins in the brown alga Fucus vesiculosus, with implications on their ecological functions.
TL;DR: A quantification procedure is modified to measure, for the first time, the amount of cell-wall-bound phlorotannins, which appears to be a secondary function in brown algae, while the effects of nutrient shortage and herbivory on the rate of phlorOTannin exudation are examined.

A rapid and sensitive method for the quantitation of microgram quantities of protein utilizing the principle of protein-dye binding
TL;DR: This assay is very reproducible and rapid with the dye binding process virtually complete in approximately 2 min with good color stability for 1 hr with little or no interference from cations such as sodium or potassium nor from carbohydrates such as sucrose.

A simple procedure for removal of Triton X-100 from protein samples.
TL;DR: A simple procedure is described for removal of Triton X-100 from protein samples by adsorption of the detergent on a commercial copolymer in bead form with no loss or dilution of protein.

Histochemistry and identification of condensed tannin precursors in roots of cotton seedlings
M. E. Mace,C. R. Howell +1 more
TL;DR: Histochemical studies revealed the localization of the catechins in the hypodermis, endoderm is, scattered cells of the xylem parenchyma, and the proximal portion of the root cap.
