The antiinflammatory effect of the total flavonoids of Laggera pterodonta (TFLP) was evaluated with various in vivo models of both acute and chronic inflammation. In the acute inflammation tests, TFLP significantly inhibited xylene-induced mouse ear oedema, carrageenan-induced rat paw oedema and
The influenza virus is a pathogen that can cause pandemic and epidemic outbreaks, and therefore represents a severe threat to human health. Antiviral drugs have an important role in the prevention and treatment of influenza, although the increasing emergence of drug resistance has given rise to a
BACKGROUND
Laggera alata, as a traditional Chinese herbal medicine, has been widely used to ameliorate some ailments associated with inflammation including hepatitis in folk.
OBJECTIVE
Based on anti-inflammatory activity of total phenolics from Laggera alata (TPLA), to further validate the
Laggera plants are traditionally used as folk medicine to treat bacterial infection, inflammation and fever in China. Three species, Laggera alata, L. intermedia and L. pterodonta, grow in China. Modem clinical studies show that L. pterodonta is a good medicine against inflammation. More than 100
The anti-inflammatory effect of total phenolics from Laggera alata (TPLA) was evaluated with various in vivo models of both acute and chronic inflammations. In the acute inflammation tests, TPLA inhibited significantly xylene-induced mouse ear oedema, carrageenan-induced rat paw oedema and acetic
Laggera pterodonta is commonly used for treating influenza in Southwest China, especially in Yunnnan province. The main clinical effects of L. pterodonta include anti-influenza, anti-microbial, anti-inflammatory. To investigate the anti-influenza A (H1N1) virus effect of L. pterodonta,
Influenza viruses can bring about acute respiratory diseases and are a potential hazard to human health. Antiviral drugs are the main ways to control the influenza virus infection except the vaccine. In this study, the immune regulation activity of pterodontic acid isolated from Laggera pterodonta
Artemitin, a significant flavonol compound existing in Laggera pterodonta (DC.) Benth., Artemisia rupestris L, etc., is the subject of attention by researchers owing to its pharmacological activities (such as antioxidative, anti-inflammatory and antiviral). In this work, a highly sensitive and
The anti-hepatitis B activity of 3,4-O-dicaffeoylquinic acid isolated from Laggera alata was studied using the D-galactosamine- (D-GalN-) induced hepatocyte damage model, HepG2.2.15 cells, and with HBV transgenic mice. In vitro results showed that 3,4-O-dicaffeoylquinic acid improved HL-7702
Eudesmane-type sesquiterpenes are natural sesquiterpenes with anti-inflammatory properties, but their anti-angiogenic activities are not known. The present study demonstrated that 5α-hydroxycostic acid and hydroxyisocostic acid, two eudesmane-type sesquiterpenes (ETSs), isolated from the herb
The hepatoprotective activities of total flavonoids of Laggera alata (TFLA) were evaluated by carbon tetrachloride (CCl(4))-induced injury in primary cultured neonatal rat hepatocytes and in rats with hepatic damage. In vitro, TFLA at a concentration range of 1-100 microg/ml improved cell viability
BACKGROUND
Influenza virus poses serious threats to human health, especially human infection with avian influenza virus. Laggera pterodonta (DC.) Benth is a medicinal plant that is widely used in Traditional Chinese Medicine, especially in Yunnan province, and has been used to treat influenza,
Liver fibrosis, a chronic damage process related to further progression of hepatic cirrhosis, has yet no truly effective treatment. Isochlorogenic acid A (ICQA), isolated from a traditional Chinese herbal medicine named Laggera alata (DC.) Sch.Bip. ex Oliv. (Asteraceae), is proved to exhibit
