Anthraquinones from Polygonum cuspidatum as tyrosinase inhibitors for dermal usePhytotherapy Research - Tập 22 Số 4 - Trang 552-556 - 2008
Yann‐Lii Leu, Tsong‐Long Hwang, Jiuan‐Wen Hu, Jia‐You Fang
AbstractFour anthraquinones, physcion (1), emodin (2), citreorosein (3) and
anthraglycoside B (6), and two stilbenes, resveratrol (4), and piceid (5), were
isolated previously from the root of Polygonum cuspidatum. These bioactive
compounds were examined for their antityrosinase potency. No antityrosinase
activity was detected with treatment using stilbenes. On the other hand, the
anthraquinones s... hiện toàn bộ
Antibacterial and Antimycobacterial Lignans and Flavonoids from Larrea tridentataPhytotherapy Research - Tập 26 Số 12 - Trang 1957-1960 - 2012
Juan Manuel Favela-Hernández, Abraham García, Elvira Garza‐González, Verónica M. Rivas-Galindo, María del Rayo Camacho‐Corona
Three lignans and four flavonoids were isolated and characterized from Larrea
tridentata and compounds were tested against 16 bacterial species/strains.
Results showed that: dihydroguaiaretic acid (1) had activity towards methicillin
resistant (MR) Staphylococcus aureus (minimum inhibitory concentration (MIC)
50 µg/mL) and multidrug‐resistant (MDR) strains of Mycobacterium tuberculosis
(MIC 12.5–5... hiện toàn bộ
Vitexin, orientin and other flavonoids from Spirodela polyrhiza inhibit adipogenesis in 3T3‐L1 cellsPhytotherapy Research - Tập 24 Số 10 - Trang 1543-1548 - 2010
Jin-Pyo Kim, Ik‐Soo Lee, JeongJu Seo, Mun Yhung Jung, Young‐Hee Kim, Nam–Hui Yim, KiHwan Bae
AbstractTo investigate the adipogenesis inhibitory effect on lipid accumulation,
3T3‐L1 cells were treated with fractions and isolated flavonoids of Spirodela
polyrhiza. An ethanol extract of S. polyrhiza was fractionated into three
fractions. The butanol soluble fraction (SPB) exhibited potent antiadipogenesis
activity and decreased C/EBPα and PPARγ protein expression level in 3T3‐L1 cells

Trifolium L. – A review on its phytochemical and pharmacological profilePhytotherapy Research - Tập 23 Số 3 - Trang 439-446 - 2009
Temine Şabudak, Necmettin Güler
AbstractPlants from the genus Trifolium have been used in traditional medicine
by many cultures. In Turkish folk medicine, for example, some Trifolium species
are used for their expectorant, analgesic, antiseptic properties and also to
treat rheumatic aches. Some species are also grown as pasture crops for animals
in the Mediterranean. The high quercetin concentration and soyasaponin
occurrence ma... hiện toàn bộ
Licoflavone C attenuates the genotoxicity of cancer drugs in human peripheral lymphocytesPhytotherapy Research - Tập 22 Số 12 - Trang 1650-1654 - 2008
Roberto Scarpato, Letizia Paganucci, Alessandra Bertoli, Lisa B. Fiore, Luisa Pistelli, Giovanni Federico
AbstractFlavonoids exhibit a wide spectrum of biological activities that can
lead to beneficial effects for human health. The search for cytotoxic, genotoxic
and/or antimutagenic natural compounds is therefore of great relevance,
especially in cancer chemotherapy. In view of this, we screened the potential
genotoxicity/antigenotoxicty of licoflavone C (LFLC) – a naturally occurring
prenyl‐flavone ... hiện toàn bộ
Polar Constituents of Marrubium thessalum Boiss. & Heldr. (Lamiaceae) and their Cytotoxic/Cytostatic ActivityPhytotherapy Research - Tập 26 Số 12 - Trang 1800-1806 - 2012
Aikaterini Argyropoulou, Pinelopi Samara, Ourania E. Tsitsilonis, Helen Skaltsa
The methanol extract of the aerial parts of Marrubium thessalum Boiss. & Heldr.
(Lamiaceae) afforded 30 phenolic metabolites, belonging to the classes of
phenylethanoid glycosides, flavonoids and simple phenolic compounds. The crude
methanol extract as well as the secondary metabolites were screened for their
cytotoxic/cytostatic effects against four human cancer cell lines, specifically

AbstractThe presence and distribution of biosynthetically related di‐ and
terthiophenes from 25 crude drugs derived from some genera of the family
Compositae were investigated by high performance thin layer chromatography
(HPTLC) densitometry. A significant thiophene content was found in Tagetes

Inhibition of cholesterol biosynthesis in HepG2 cells by artichoke extracts is reinforced by glucosidase pretreatmentPhytotherapy Research - Tập 16 Số 4 - Trang 368-372 - 2002
Rolf Gebhardt
AbstractHigh‐dose aqueous extracts from artichoke leaves were found to inhibit
cholesterol biosynthesis from 14C‐acetate rather moderately in HepG2 cells in
contrast to primary cultured rat hepatocytes in which the inhibition was
stronger. Preincubation of the extracts with several glycohydrolases revealed
that pretreatment with β‐glucosidase considerably reinforced the inhibition. A
