TLDR
The reversed-phase preparative HPLC analysis of the methanol extract of the rhizomes of Eremostachys glabra (Lamiaceae) led to the isolation of two furanolabdane diterpene glycosides, phlomisoside II, and β-D-glucopyranosyl-(1→2)-β-DAbout:

GC-MS analysis of the essential oils, and the isolation of phenylpropanoid derivatives from the aerial parts of Pimpinella aurea
Abbas Delazar,Fahimeh Biglari,Solmaz Esnaashari,Hossein Nazemiyeh,Amir-Hossein Talebpour,Lutfun Nahar,Satyajit D. Sarker +6 more
TL;DR: A combination of vacuum liquid Chromatography (VLC) and preparative thin layer chromatography (PTLC) of the dichloromethane extract of the aerial parts of the Iranian plant Pimpinella aurea afforded two phenylpropanoids, erythro-1'-(4-methoxyphenyl)-propan-1',2'-diol (1), the latter being a natural product.

Antioxidant phenolic compounds from the leaves of Erica Arborea (Ericaceae)
Hossein Nazemiyeh,Fatemeh Bahadori,Abbas Delazar,Mehmet Ay,Gulacti Topcu,Lutfun Nahar,Runner R. T. Majinda,Satyajit D. Sarker +7 more
TL;DR: Reversed-phase HPLC analyses of the methanol extract of the leaves of Erica arborea afforded a novel phenylpropanoid glucoside, named ericarborin, together with five flavonoids, which were determined by direct comparison of their spectroscopic data with respective literature data.

A Simple Screening Method for Antioxidants and Isolation of Several Antioxidants Produced by Marine Bacteria from Fish and Shellfish
TL;DR: A simple screening method using 1,1-diphenyl-2-picrylhydrazyl (DPPH) and screened bacteria from 16 kinds of marine animals that lived in different environments in the sea to find 112 bacterial isolates-producing antioxidants, strongly suggesting that the bacterial production of the antioxidative compounds is a kind of adaptation to the aerobic conditions.

6-Hydroxyluteolin and scutellarein as phyletic markers in higher plants
TL;DR: 6-hydroxyluteolin is present in the majority as a leaf constituent in some highly specialized herbaceous families and its distribution patterns indicate that the ability to hydroxylate flavones in the 6-position arose relatively late in evolutionary time.

Anatomical, cytological and phytochemical studies on Phlomis L. and Eremostachys Bunge (Labiatae)
D. Azizian,David F. Cutler +1 more
TL;DR: Observations made on the anatomy of Phlomis and Eremostachys confirm previous views that the two genera are closely related, but characters such as trichomes and petiole structure can be used to distinguish species and groups of species.
