One new phenanthrene derivative phoimbrtol A (1) with seven known compounds, loddigesiinol B (2), shanciol B (3), (–)-medioresinol (4), (–)-pinoresinol (5), quercetin 3-O-β-l-arabinofuranoside (6), luteolin 7-O-β-glucoside (7) and platycaryanin D (8) have been isolated from the ethyl acetate extract of the air-dried whole plant of Pholidota imbricata Hook. Their inhibitory effects on nitric oxide (NO) production and 1,1-diphenyl-2-picrylhydrazil (DPPH) radical scavenging activity were examined… 
Antioxidant activity and kinetics studies of eugenol and 6-bromoeugenol
TLDR
The antioxidant and free radical scavenging activity of 6-bromoeugenol and eugenol was evaluated using 2,2-diphenyl-1-picrylhydrazyl radical-scavenging method and results have shown high ARE.
Phenanthrenes from Arundina graminifolia and in vitro evaluation of their antibacterial and anti-haemolytic properties.
TLDR
It was found that compounds 1 and 2 had medium antibacterial activity against Staphylococcus aureus, Bacillus subtilis and Escherichia coli, with MICs of 20-40 μg/mL and MBCs of 40-320 μG/mL.
A new (propylphenyl)bibenzyl from Eria bambusifolia
TLDR
All the compounds isolated were evaluated for their cytotoxicity against human tumour HL-60, SMMC-7721, A-549, MCF-7 and SW-480 cell lines, but none showed significant activity.
Phenanthrenes from Arundina graminifolia and in vitro evaluation of their antibacterial and anti-haemolytic properties
TLDR
It was found that compounds 1 and 2 had medium antibacterial activity against Staphylococcus aureus, Bacillus subtilis and Escherichia coli, and compounds 1–3 attenuated the erythrocyte damage.

A New Phenanthrene Derivative with α-Glucosidase Inhibitory Activity from Pleione maculata
A new phenanthrene, 2,3,7-trihydroxy-4,8-dimethoxyphenanthrene ( 1 ), was isolated from Pleione maculata . Its structure was determined on the basis of NMR (1D and 2D) and HR-ESI-MS data. The new
A new flavone C-glycoside and a new bibenzyl from Bulbophyllum retusiusculum
TLDR
Compounds 1 and 2 showed no obvious cytotoxic activity against any five human tumour cell lines with IC50 values >40 μM and were isolated from the tubers of Bulbophyllum retusiusculum.

New phenanthrenes and stilbenes from Dendrobium loddigesii.
TLDR
It is suggested that this phenanthrene is a stronger inhibitor of NO production than dihydrophenanthrene, which has shown significant inhibitory activity against nitric oxide production.
Stilbene derivatives from Pholidota chinensis and their anti-inflammatory activity.
TLDR
Ethyl acetate extract of Pholidota chinensis L. showed strong NO production inhibitory activity in murine macrophage-like cell line, RAW 264.7, which was activated by a lipopolysaccharide and interferon-gamma and led to the isolation of two new stilbene derivatives.
Flavonol glycosides from Dryas octopetala.
Six flavonol glycosides and ent-epicatechin were isolated from Dryas octopetala and their structures elucidated by chemical and spectroscopic methods. Two new flavonoids,
Antifibrotic phenanthrenes of Dendrobium nobile stems.
TLDR
Antifibrotic activity of compounds 1- 19 was evaluated employing HSC-T6, an immortalized rat hepatic stellate cell line, as an in vitro assay system by assessing cell proliferation.
Inhibitory effects of hydrolyzable tannins from Melastoma dodecandrum Lour. on nitric oxide production by a murine macrophage-like cell line, RAW264.7, activated with lipopolysaccharide and interferon-gamma.
TLDR
The results suggest that MDL has the pharmacological ability to suppress NO production by activated macrophages and that the hydrolyzable tannins have major inhibitory activities.
A new lignan from Balanophora abbreviata and inhibition of lipopolysaccharide (LPS)-induced inducible nitric oxide synthase (iNOS) expression.
Six lignans including a new lignan (1), beta-sitosterol glucopyranoside and phenylpropanoids were isolated from the whole plants of Balanophora abbreviata Bl. (Balanophoraceae). Their structures were
Flavan-3-ols and dihydrophenanthropyrans from Pleione bulbocodioides
Benzophenone glycosides from Gnidia involucrata.
