Centella asiatica (L.) Urban is a medicinal herb traditionally used in Asiatic countries for its multiple therapeutic properties, essentially due to its accumulation of specific pentacylic triterpenoid saponins, mainly asiaticoside and madecassoside and the corresponding sapogenins. This review summarizes the updated knowledge about the chemical structures of about forty centelloids, found as minor metabolites in Centella, and all derived from ursane and oleane ring patterns. Similarly, the most recent genetic and enzymatic features involved in their biosynthesis is reviewed, in relation with their biotechnological production developed, either from in vitro plant cultures or undifferentiated cells, in order to be independent of natural sources and to provide a continuous and reliable source of centelloids...

Sodium alginate and chitosan were in favor of wound healing. However, the two polymers were not compatible in one formulation due to the electrostatic interaction. Coaxially electrospinning technology could make two or more noneletrospun polymers to be electrospun in independent core and shell layer. Asiaticoside-loaded coaxially electrospinning nanofibers of alginate, polyvinyl alcohol (PVA) and chitosan (alginate/PVA/chitosan) were prepared and evaluated. Morphologies and microstructure of nanofibers were observed with scanning electron microscopy (SEM) and transmission electron microscopy (TEM)...

The increase in endothelial permeability often promotes edema formation in various pathological conditions. Tumor necrosis factor-alpha (TNF-α), a pro-atherogenic cytokine, impairs endothelial barrier function and causes endothelial dysfunction in early stage of atherosclerosis. Asiaticoside, one of the triterpenoids derived from Centella asiatica, is known to possess antiinflammatory activity. In order to examine the role of asiaticoside in preserving the endothelial barrier, we assessed its effects on endothelial hyperpermeability and disruption of actin filaments evoked by TNF-α in human aortic endothelial cells (HAEC)...
