The ursane triterpenoids, asiatic acid 1 and madecassic acid 2, are the major pharmacological constituents of Centella asiatica, commonly known as Gotu Kola, which is used traditionally for the treatment of anxiety and for the improvement of cognition and memory. Using the two-electrode voltage-clamp technique, these triterpenes, and some semisynthetic derivatives, were found to exhibit selective negative modulation of different subtypes of the GABAA receptor expressed in Xenopus laevis oocytes. Despite differing by only one hydroxyl group, asiatic acid 1 was found to be a negative modulator of the GABA-induced current at α1 β2 γ2L, α2 β2 γ2L and α5 β3 γ2L GABAA receptors, while madecassic acid 2 was not...

Abstract Centella asiatica (Gotu Kola) is a plant that grows in tropical swampy regions of the world and has important medicinal and culinary use. It is often considered as part of Ayurvedic medicine, traditional African medicine, and traditional Chinese medicine. The unavailability of genomics resources is significantly impeding its genetic improvement. To date, no attempt has been made to develop Expressed Sequence Tags (ESTs) derived Simple Sequence Repeat (SSR) markers (eSSRs) from the Centella genome. Hence, the present study aimed to develop eSSRs and their further experimental validation and cross-transferability of these markers in different genera of the Apiaceae family to which Centella belongs...

Centella asiatica (CA), commonly named gotu kola, is an Ayurvedic herb used to enhance memory and nerve function. To investigate the potential use of CA in Alzheimer's disease (AD), we examined the effects of a water extract of CA (GKW) in the Tg2576 mouse, a murine model of AD with high β-amyloid burden. Orally administered GKW attenuated β-amyloid-associated behavioral abnormalities in these mice. In vitro, GKW protected SH-SY5Y cells and MC65 human neuroblastoma cells from toxicity induced by exogenously added and endogenously generated β-amyloid, respectively...

Self-administration of complementary products concurrently with conventional medication is increasingly common. The potential for cytochrome P450 (CYP) inhibition requires investigation. The N-in-one assay with ten probe substrates for nine CYPs was used with human liver microsomes to investigate ten products. CYP inhibition was measured in a single liquid chromatography-tandem mass spectrometry (LC/MS-MS) analysis. Estimated IC(50)-values were determined for the extracts that produced significant inhibition (less than 100 microg ml(-1))...
