The aim of this study was to investigate the chemical constituents of Lindera erythrocarpa essential oil (LEO) by gas chromatography-mass spectrometry and evaluate their inhibitory effect on the expression of pro-inflammatory mediators in lipopolysaccharide (LPS)-stimulated RAW264.7 cells. Fifteen
Here, we investigated the anti-inflammatory activity of lucidone, a phytocompound isolated from the fruits of Lindera erythrocarpa Makino, against lipopolysaccharide (LPS)-induced acute systemic inflammation in mice. Male ICR mice were injected intraperitoneally with LPS (5 microg/kg), and the
Four new sesquiterpenes (1-4), one new alkaloid (5), and one new benzenoid glycoside (6) were characterized from Lindera aggregata, and their structures were elucidated according to their spectrometric analytical data. Among these isolates, 3 and 4 were constructed as possessing unprecedented carbon
In this study, in vitro and in vivo antiinflammatory activities of fruits from Lindera erythrocarpa Makino were evaluated. The ethyl acetate soluble fraction derived from the ethanol extract of L. erythrocarpa fruits inhibited significantly nitric oxide (NO) production in lipopolysaccharide (LPS)
A new butanolide, 3β-((E)-dodec-1-enyl)-4β-hydroxy-5β-methyldihydrofuran-2-one (1) and four known butanolides: Akolactone A (2), (3Z,4α,5β)-3-(dodec-11-enylidene)-4-hydroxy-5-methylbutalactone (3), (3E,4α,5β)-3-(dodec-11-enylidene)-4-hydroxy-5-methylbutalactone (4) and dihydroisoobtusilactone (5),
Obesity and its associated health risks still demand for effective therapeutic strategies. Drugs and compositions derived from Oriental medicine such as green tea polyphenols attract growing attention. Previously, an extract from the Japanese spice bush Lindera obtusiloba (L. obtusiloba)
Ethnopharmacological relevance: Penyanling is made up of Smilacis Glabrae Rhizoma (SG, from Smilar glabra Roxb.), Angelicae Sinensis Radix (AS, from Angelica sinensis (Oliv.) Diels), Salviae Miltiorrhizae Radix et Rhizoma (SM, from Salvia
Obesity, the related metabolic syndrome and associated liver diseases represent an epidemic problem and demand for effective therapeutic strategies. In this regard, natural compounds derived from Oriental medicine such as green tea polyphenols influencing adipogenesis attract growing attention. In
The pseudoguaianelactones A (1) and B (2), two novel sesquiterpene lactones with an unprecedented [5,7,7] ring system featuring an α-methylene-γ-lactone moiety, together with a new pseudoguaianelactone C (3) were isolated from the roots of Lindera glauca. Pseudoguaianelactones A-C (1-3) inhibited
Inflammation is related to many diseases. Lindera akoensis Hayata was often used in folktherapy in Taiwan for inflammation. In this study, three new flavonol acyl glycosides, namelykaempferol-3-O--D-4",6"-di-(E)-p-coumaroylglucoside (1), 3"-(E)-p-coumaroylafzelin (2) and
We investigated the protective effects of lucidone, a naturally occurring cyclopentenedione isolated from the fruits of Lindera erythrocarpa Makino, against free-radical and inflammation stimulator 2,2'-azobis (2-amidinopropane) dihydrochloride (AAPH)-induced oxidative stress in human keratinocyte
OBJECTIVE
To study the antibacterial and anti-inflammatory constituents of the leaves of Lindera aggrega.
METHODS
Compounds were isolated by colum chromatography, and the structures were identified by spectroscopic methods.
RESULTS
Six compounds were isolated and identified as mixture of
Lindera aggregata (Sims) Kosterm. belongs to Lauraceae family and is distributed in the southern parts of China, Japan and southeastern Asia. The leaves of this plant are frequently used in folk medicine, as antioxidant, antiinflammatory and antibacterial. In previous reports, eleven flavones were
A bioassay-guided fractionation and chemical investigation of the MeOH extract from the twigs of Lindera glauca (SIEB. et ZUCC.) BLUME resulted in the isolation and identification of six lignans (1-6) including three new lignan derivatives, named linderuca A (1), B (2), and C (3). The structures of
Four new secondary metabolites, 3α-((E)-Dodec-1-enyl)-4β-hydroxy-5β-methyldihydrofuran-2-one (1), linderinol (6), 4'-O-methylkaempferol 3-O-α-L-(4''-E-p-coumaroyl)rhamnoside (11) and kaempferol 3-O-α-L-(4''-Z-p-coumaroyl)rhamnoside (12) with eleven known compounds-3-epilistenolide D1 (2),
