Fungal exudate is the phenomenon that involves the exudation of water and metabolites produced by fungal cells, Fungal exudates are rich sources of bioactive secondary metabolites with potential applications. Exudates are a prevalent phenomenon in the fungal domain, influenced by various factors, such as the composition of the growth medium and incubation temperature. Filamentous fungi, renowned for their extensive metabolic capabilities, release exudates that act as reservoirs for a wide range of bioactive compounds. These exudates, often underexplored, contain diverse secondary metabolites and proteins with significant biological activities. From Centella asiatica, 30 fungal isolates were obtained, of which 12 were analyzed based on morphological and cultural characteristics. Among these, Talaromyces verruculosus and Penicillium chrysogenum exhibited exudate production. SEM analysis highlighted the structural morphology of the fungi, while ATR- FTIR revealed the presence of diverse functional groups, indicative of a complex chemical composition, Exudates from T. verruculosus exhibited hydroxyl (-OH) stretch, isothiocyanate (-NCS), conjugated alkene, allenes, amines, and aliphatic iodo compounds. In contrast, P. chrysogenum exudates contained secondary amines, carbodiimides,...

Wound healing remains a significant challenge in modern medicine, necessitating the exploration of innovative therapeutic strategies. Centella asiatica, a widely recognized medicinal herb, has garnered attention for its potential wound healing properties. This study aimed to investigate the efficacy of a Centella asiatica transdermal patch in promoting wound healing. These results suggest that the Centella asiatica transdermal patch holds promise as a novel therapeutic intervention for promoting wound healing. Further research is warranted to elucidate the underlying mechanisms of action and optimize the formulation of the patch for clinical application. This study contributes to the growing body of evidence supporting the use of herbal remedies in wound management and underscores the potential of Centella asiatica as a valuable adjunctive therapy in wound healing. This study investigates the wound healing activity of a transdermal patch containing a combination of Centella asiatica and Liquorice extracts. The patch was formulated and evaluated for its efficacy in promoting wound healing using in-vitro and in-vivo assays. Overall, this study suggests that the Centella asiatica...

Centella asiatica (Linn) Urban, a herb of immense medicinal properties, has been widely used by traditional healers in the treatment of skin diseases, mental fatigue, anxiety, rheumatism, eoilepsy and leprosy. In the present investigation, the antibacterial activity of ethanol, acetone and aqueous extracts of Centella asiatica were tested in-vitro against seven bacterial species viz. Staphylococcus aureus, Salmonella typhi, Salmonella paratyphi, Klebsiella sp., E. coli, Bacillus sp. and Pseudomonas sp. by well diffusion method. The ethanol extract inhibited the growth of Bacillus sp. and S. aureus, maximally (14 mm each), followed by that of E. coli (12 mm) and Klebsiella sp. (11 mm). The extract unaffected the growth of Salmonella typhi, Pseudomonas, and Salmonella paratyphi. The acetone extract inhibited the growth of Bacillus sp. (10 mm); the other six bacteria remained unaffected. Likewise, the aqueous extract also inhibited the growth of none of the test bacteria in this...

Ulcerative colitis was defined as a common intestinal infla-mmatory disease characterized by upregulation of pro-inflammatory cytokines and oxidative stress. The leaves of Murraya koenigii and Centella asiatica had been used in traditional medicine to treat the disease. The present study aimed to perform a comparative protective efficacy evaluation between Murraya koenigii and Centella asiatica on acetic acid-induced ulcerative colitis in rats. Rats were randomly categorized into nine groups: control, acetic acid, standard drug, acetic acid + extract of Murraya koenigii (50, 100, 200 mg/kg), and acetic acid + extract of Centella asiatica (50, 100, 200 mg/kg) groups. After 5 days of feeding, colitis was induced in the experimental animal groups by transrectal administration of 1ml of 4% acetic acid. The rats were sacrificed after 24 hr of rectal installation, and their colon tissues were examined. Pretreatment with extract of Murraya koenigii and Centella asiatica significantly reduced colon weight-length, macroscopic scores, histological changes, and upregulated the enzymatic activity of superoxide dismutase (SOD). The above results indicated that oral administration of...

The research aim is to develop and evaluate Centella asiatica Chloroform extract and silver-coated suture against the most common organisms that cause surgical site infections (SSI) by in-vitro methods. This prospective study is to coat the Centella asiatica (CA) extract to the suture along with the silver nitrate solution. In this study, a suture filament was formulated with Poly Lactic Glycolic Acid (PLGA) (50:50 ratio). A formulated filament was coated with Centella asiatica extract, and its property was compared with the marketed future. After minor modifications, the marketed suture was coated with Centella asiatica extract. Antibacterial efficacy of Centella asiatica extract coated suture filaments with and without silver nitrate solution were evaluated against gram-positive and gram-negative bacteria. Chloroform extract of Centella asiatica powder was effective against gram positive and negative bacteria compared to crude powder. Particle size and Zeta potential of the CA powder extract with and without silver nitrate at the end of 3 h was found to be 676.9 and 140.1nm and 0.295 1.45mv of Zeta potential,...
