Flavonoids, triterpenoids and a lignan from Vitex altissima
TLDR
A new tetrahydrofuranoid lignan, altissinone and a new acylated flavone C-glucoside, 2''-O-p-hydroxybenzoylorientin were isolated in addition to several known triterpene acids and flavonoids from the ethyl acetate extractives of the leaves of Vitex altissima.About:

Flavone 8‐C‐Glycosides from Haberlea rhodopensis Friv. (Gesneriaceae)
Samad Nejad Ebrahimi,Samad Nejad Ebrahimi,Frank Gafner,Giorgio Dell'acqua,Kuno Schweikert,Matthias Hamburger +5 more
TL;DR: In this article, a combination of liquid/liquid extraction and HPLC analysis of a MeOH extract from Haberlea rhodopensis was used to identify new flavone C-glycosides, including myconoside and paucifloside.

In search of cyclooxygenase inhibitors, anti-Mycobacterium tuberculosis and anti-malarial drugs from Thai flora and microbes.
George A. Gale,Kanyawim Kirtikara,Pattama Pittayakhajonwut,Somsak Sivichai,Yodhathai Thebtaranonth,Chawanee Thongpanchang,Vanicha Vichai +6 more
TL;DR: Diversities of Thai flora and fungi and their chemical constituents with antagonistic properties against these 2 diseases are described in detail and anti-inflammatory compounds, mostly cyclooxygenase (COX) inhibitors, are described herein to demonstrate the potential of Thai bioresources to provide a wide array of compounds for treatment of diseases of a different nature.

Pterosins from Pteris multifida
TL;DR: In this paper, a new C 14 pterosin sesquiterpenoid, named (2 R)-pterosin P (1), and a new natural product, named dehydropterosIN B (3), were isolated from the aerial parts of PTERIS MULTIFIDA Poir, along with nine known compounds.

Anti-Inflammatory Activity of Vitex leucoxylon L. Bark Extracts Against Freund's Complete Adjuvant Induced Arthritis in Sprague Dawley Rat
Alluri V. Krishnaraju,Chundi B.M. Rao,Dodda Sundararaju,Krishanu Sengupta,Golakoti Trimurtulu +4 more
TL;DR: Oral supplementation of Vitex leucoxylon L., a medicinal plant of the verbenaceae family, resulted in significant anti-inflammatory effects as indicated by reduction in paw edema both at 100 and 250 mg kg-1 doses when compared to untreated rats, indicating that VL-89/185A is a safe intervention for inflammatory disorders.

Superoxide Dismutase AN ENZYMIC FUNCTION FOR ERYTHROCUPREIN (HEMOCUPREIN)
Joe M. McCord,Irwin Fridovich +1 more
TL;DR: The demonstration that O2·- can reduce ferricytochrome c and tetranitromethane, and that superoxide dismutase, by competing for the superoxide radicals, can markedly inhibit these reactions, is demonstrated.

Carrageenin-Induced Edema in Hind Paw of the Rat as an Assay for Antiinflammatory Drugs
TL;DR: The potency ratios obtained for aspirin, phenylbutazone and hydrocortisone are fairly close to the ratios of their respective daily doses in the treatment of rheumatic disease.

Carbon-13 NMR studies of flavonoids. III. Naturally occurring flavonoid glycosides and their acylated derivatives
TL;DR: In this article, 13 C NMR spectra for a variety of flavonoid glycosidcs are presented and analyzed, and evidence is presented which demonstrates that 13 C nMR spectroscopy is a valuable technique for distinguishing the sites of methylation, glycosylation and acylation in glycoiides.

[Medicinal Lamiaceae with antioxidant properties, a potential source of rosmarinic acid].
TL;DR: Hydroalcholic extracts from four native medicinal Lamiaceae, Lycopus europaeus L., Melissa officinalis L., Origanum vulgare L. and Prunella vulgaris L. have shown significant antioxidative activities, by free radical scavenger effect on DPPH, compared with those of Rosmarinus officinal is L. extracts.

Perchloric acid enhances sensitivity and reproducibility of the ferric-xylenol orange peroxide assay.
TL;DR: The ferrous oxidation in xylenol orange (FOX) assay for hydroperoxides suffers from very narrow pH optimum in the range 1.7-1.8, and substitution of perchloric for the sulfuric acid resulted in a lowering of the optimum pH of the assay to 1.1, a decreased dependence of the absorbance of the ferric-xylenl orange complex on acid concentration and decreased sensitivity to added compounds.
