Ueber Parthenogenesis bei Houttuynia cordata

Cytotoxic alkaloids from Houttuynia cordata.

Six bioactive alkaloids, aristolactam B(1), piperolactam A(2), aristolactam A(3), norcepharadione B(4), cepharadione B(5) and splendidine(6) were isolated by bioactivity-guided fractionation of a methanolic extract of the aerial part of Houttuynia cordata. Several of them exhibited significant cytotoxicity against five human tumor cell lines (A-549, SK-OV-3, SK-MEL-2, XF-498 and HCT-15) in vitro.

Increased Flavonoid Compounds from Fermented Houttuynia cordata using Isolated Six of Bacillus from Traditionally Fermented Houttuynia cordata

Flavonoids, which form a major component in Houttuynia cordata Thunb., display a wide range of pharmacological activities. The expression of plant flavonoids is partly regulated by fermentation. Therefore, we studied the effects of fermentation on H. cordata in order to identify the strains present during the fermentation process, and to determine whether fermented H. cordata could be used as a...

Preventive Effects of Houttuynia cordata Extract for Oral Infectious Diseases

Houttuynia cordata (HC) (Saururaceae) has been used internally and externally as a traditional medicine and as an herbal tea for healthcare in Japan. Our recent survey showed that HC poultice (HCP) prepared from smothering fresh leaves of HC had been frequently used for the treatment of purulent skin diseases with high effectiveness. Our experimental study also demonstrated that ethanol extract...

Anti-inflammatory effects of a Houttuynia cordata supercritical extract

Anti-inflammatory effects of Houttuynia cordata supercritical extract (HSE) were investigated in a carrageenan-air pouch model. HSE (200 mg/kg, oral) suppressed exudation and albumin leakage, as well as inflammatory cell infiltration. Dexamethasone (2 mg/kg, i.p.) only decreased exudation and cell infiltration, while indomethacin (2 mg/kg, i.p.) reduced exudate volume and albumin content. HSE l...
