Asiaticoside is a natural compound possessing diverse pharmacological effects with great potential for clinical use. However, the low solubility and oil-water partition coefficient of asiaticoside lead to reduced effect and limited application. This study aims to construct a porous microsphere for the sustained release of asiaticoside to improve its absorption and enhance the therapeutic effects. Parameters of the formulations, including the drug to polymer ratio, solvent amounts of the inner and external phases, the stirring speed for preparation, and the drug entrapment efficiency were investigated and optimized...

The healing of burn wounds has been widely characterized to be highly intricate, involving processes such as neo-vascularization, granulation, re-epithelialization, inflammation and wound contraction. Various therapies are available for the management of burn wounds; however, a truly effective therapeutic strategy has yet to be identified due to safety issues. The aim of the present study was to assess and confirm the burn wound healing properties of the compounds asiaticoside (AE) and madecassoside (MA), which are found in the herb Centella asiatica...

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)...

Centella asiatica was extracted by methanol. The assay content of triterpenes in the extract was 0.12 % asiatic acid, 0.54 % madecassic acid, 0.25 % asiaticoside and 1.02 % madecassoside. The extract was complexed with hydroxypropyl-β-cyclodextrin (HP-β-CD) and formulated with Eudragit E100, glycerol, PEG 400, copovidone, ethanol and purified water. A clear yellowish solution (F1-F8) was obtained. The formulations had a pH of 5.5-6.0 with viscosity in the range of 20-60 mPa s, surface tension 20.3-24.6 mN m-1 and contact angle less than 20°...

Centella asiatica (L.) Urban (Apiaceae), a small annual plant that grows in India, Sri Lanka, Malaysia, and other parts of Asia, is well-known as a medicinal herb with a long history of therapeutic uses. The bioactive compounds present in C. asiatica leaves include ursane-type triterpene sapogenins and saponins-asiatic acid, madecassic acid, asiaticoside, and madecassoside. Various bioactivities have been shown for these compounds, although most of the steps in the biosynthesis of triterpene saponins, including glycosylation, remain uncharacterized at the molecular level...

This systematic review aimed to evaluate the effects of plants on osteogenic differentiation and mineralization of human periodontal ligament cells. The included studies were selected using five different electronic databases. The reference list of the included studies was crosschecked, and a partial gray literature search was undertaken using Google Scholar and ProQuest. The methodology of the selected studies was evaluated using GRADE. After a two-step selection process, eight studies were identified. Six different types of plants were reported in the selected studies, which were Morinda citrifolia, Aloe vera, Fructus cnidii, Zanthoxylum schinifolium, Centella asiatica, and Epimedium species...

This study aims to investigate whether asiaticoside, a triterpene glycoside, can afford protection to DNA from alterations induced by gamma radiation under in vitro, ex vivo, and in vivo conditions. In vitro studies were done on plasmid pBR322 DNA, ex vivo studies were done on cellular DNA of human peripheral blood leukocytes, and in vivo investigations were conducted on cellular DNA of spleen and bone marrow cells of mice exposed to whole-body gamma radiation. The supercoiled form of the plasmid pBR322 DNA upon exposure to the radiation was converted into relaxed open circular form due to induction of strand breaks...

This study is to investigate the potential role of asiaticoside (AS) in Aβ1-42-induced apoptosis on the human umbilical vein endothelial cell (HUVEC). HUVEC cells were divided into Aβ1-42 group (treated with 50 μM Aβ1-42), AS groups (treated with 50 μM Aβ1-42 and 10 mM, 1 mM, 0.1 mM or 0.01 mM AS), and negative control group (without treatments). Cell proliferation was detected by CCK-8 assay. Apoptosis was analyzed by Hochest33342 staining and flow cytometry. Western Blot was carried out to detect the expression of Bcl-2 and Bax protein...

Asiaticoside has potent pharmacological activity and broader pharmacological effects, including anti‑oxidant, antidepressant and hepatic protection effects, and the inhibition of tumor cell proliferation. However, the mechanism underlying the effects of asiaticoside on neurological pain in spinal cord injury (SCI) remain to be fully elucidated. Therefore, the present study investigated the specific mechanism underlying the beneficial action of asiaticoside in a SCI rat model. In the present study, Basso, Beattie and Bresnahan scores was determined to analyze the therapeutic effects of asiaticoside on the neurological function of the SCI rat model...

BACKGROUND: Asiaticoside is one of the main functional components of the natural plant Centella asiatica urban. Studies have reported it has several functions such as anti-depression and nerve cell protection. Asiaticoside can reduce the cerebral infarct size in acute focal cerebral ischemia in a mouse model and asiatic acid glycosides can significantly improve neurobehavioral scores. Currently, there is a lack of understanding of asiaticoside in regard to its neural protective mechanism in cerebral ischemia...

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)...

This study was designed to investigate the protective effects of the centella triterpene saponins (EXT) on cyclophosphamide (CYP)-induced hepatotoxicity and immunosuppression in rats. The phytochemical profile of EXT was analyzed for centella saponins by using high-performance liquid chromatographic (HPLC). Therapeutic efficacy of EXT (250 mg/kg/day p.o) on hematological profile of blood, liver function markers, and cytokine profiles in CYP (10 mg/kg/day p.o)-treated rats. In addition, weights of immune organs (spleen and thymus) and histopathological changes in the liver, intestine, and spleen were also evaluated...

Diabetes-associated cognitive dysfunction, referred as "diabetic encephalopathy", has been confirmed in a great deal of literature. Current evidence support that oxidative stress, inflammation, energy metabolism imbalance, and aberrant insulin signaling are associated with cognition deficits induced by diabetes. The present study explore the effect of asiaticoside on the cognition behaviors, synapses, and oxidative stress in diabetic rats. Asiaticoside could markedly ameliorate the performance in the Morris Water Maze (decreased latency time and path length, and increased time spent in the target quadrant), which was correlated with its capabilities of suppressing oxidative stress, restoring Na(+)-K(+)-ATPase activity and protecting hippocampal synapses...
