1. In vivo anti-arthritic and antioxidant effects from the standardized ethanolic extract of Moussonia deppeana
ABSTRACT Moussonia deppeana (Schltdl. & Cham.) Klotzsch ex Hanst., Gesneriaceae, known as tlachichinole, is a Mexican medicinal plant used for treatment of chronic inflammation-related diseases such as arthritis. In this paper, the main metabolite verbascoside was quantified in ethanolic extract; anti-arthritic and antioxidant activities were also evaluated

2. Isolamento do verbacosídeo e validação de método analítico para padronização do extrato bruto das partes aéreas de Buddleja stachyoides Cham. & Schltdl. (Scrophulariaceae)
Phenylpropanoid glycoside verbascoside was isolated and identified from the ethyl acetate fraction of the aerial parts of Buddleja stachyoides Cham. & Schltdl. by 1H-NMR. A method using high-performance liquid chromatography has been developed and validated for determination of verbascoside in alcoholic crude extract of the aerial parts of B. stachyoides. An

3. Assessment of free-radical scavenging activity of Gypsophila pilulifera: assay-guided isolation of verbascoside as the main active component
Gypsophila pilulifera, Boiss & Heldr, Caryophyllaceae, is a perennial medicinal herb that grows in the southwestern region of Turkey. Except for only one report on the isolation of cytotoxic saponins from the underground parts of G. pilulifera, there are no published thorough phytochemical or bioactivity studies on this species. In the present study, the fre

4. Phytochemical study, antioxidant and antibacterial activities of Stemodia maritima
Stemodinol, a new natural compound, together with known compounds including jaceidin, stemodin, stemodinoside B, isocrenatoside, verbascoside, crenatoside, and isoverbascoside, were isolated from Stemodia maritima Linn. The antioxidant (DPPH method) and antimicrobial activities of stemodin, stemodinoside B, and crenatoside were investigated. Among the compon

5. Phytochemistry and bioactivity of Pedicularis sibthorpii growing in Iran
The methanol extract of the aerial parts of the medicinal plant Pedicularis sibthorpii Boiss., Scrophulariaceae, growing in the Azerbaijan province of Iran, was found to be active in the 2,2-diphenyl-1-picryl-hydrazyl (DPPH) and the antibacterial agar well diffusion assays, but no general toxicity was observed in the brine shrimp lethality assay. A combinati

6. Volatile and non-volatile compounds and antimicrobial activity of Mansoa difficilis (Cham.) Bureau & K. Schum: (Bignoniaceae)
Essential oil from the leaves of Mansoa difficilis was analyzed by GC/MS. Oct-1-en-3-ol (49.65%) was the major compound, but diallyl di- and trisulfide were also present (0.85 and 0.37%, respectively), justifying the garlic-like odor of the crushed leaves. The hexane and methanol extracts of the leaves and stems afforded as main constituents a mixture of lin

7. Inhibition of human platelet aggregation in vitro by standardized extract of Wendtia calycina
Wendtia calycina (Griseb.) Griseb., Vivianiaceae, is a Paraguayan herbaceous plant commonly known as burrito. Our previous study indicated that burrito leaves are a very good source of phenylpropanoid glycosides, principally verbascoside. From W. calycina leaves, a standardized, water-soluble extract rich in phenylpropanoid glycosides (WSE) has been develope

8. Antioxidant activity of natural compounds of Stachytarpheta cayennensis (Rich.) Vahl, Verbenaceae, by scavenger of mitochondrial reactive oxygen species
The etiology of a range of diseases is associated with an excessive generation of reactive oxygen species (ROS). Exacerbated ROS production leads to mitochondrial dysfunction, cellular damage and apoptosis. Nowadays, many strategies are being developed for the targeted delivery of antioxidants compounds to mitochondria, trying to minimize the damages. Produc

11. Estudo fitoquímico da fração n-butanólica de Lippia Alba (Mill.) N. E. Br.
Lippia alba is a medicinal plant wich is find in all regions of Brazil. This especie is largely used in the folk medicine, especially as a tranquilizer. It needs cientific studies about isolation and identification of its constituents. In previous studies, the n-butanolic fraction, obtained from a hidroalcoolic extract showed sedative and anticonvulsant effe

12. Dirhamnosyl flavonoid and other constituents from Brillantaisia palisatii
A mixture containing sitosterol and stigmasterol; a new triterpene 3-epi-ursolic acid; another triterpene mixture comprising a-amyrin, b-amyrin and lupeol; verbascoside, a phenylpropanoid glycoside; and lespedin, a glycosyl flavonoid, were isolated. The less polar compounds (steroids and triterpenoids) were isolated from the hexane partition of the crude eth
