Anti-aging potential and phytochemicals of Centella asiatica, Nelumbo nucifera, and Hibiscus sabdariffa extracts

Anti-allergic, anti-pruritic, and anti-inflammatory activities of Centella asiatica extracts.

This study investigated antipruritic and anti-inflammatory effect of Centella asiatica extract in rats and anti-allergic in vitro using sheep (Capra hircus) serum method and compound 48/80 induced mast cell degranulation method, compared with standard drug ketotifen fumarate. In rats, extract of Centella asiatica administered orally was examined for anti-pruritic study and chlorpheniramine male...

Evaluation of Analgesic and Anti-Inflammatory Activity of Chloroform and Methanol Extracts of Centella asiatica Linn

A variety of active constituents with wide range of pharmacological actions have been reported with Centella asiatica. The present study was undertaken to assess analgesic and anti-inflammatory properties of its leaf extracts. Dried leaves were defatted with petroleum ether and extracted with chloroform and methanol.

Anti-Angiogenic Effect of Nelumbo nucifera Leaf Extracts in Human Umbilical Vein Endothelial Cells with Antioxidant Potential

Nelumbo nucifera Gaertn (Nymphaeaceae) has long been used as a traditional herb in Chinese, Japanese, Indian, and Korean medicinal practices since prehistoric times and flourishes today as the primary form of medicine. This study reports for the first time the potent ability of N. nucifera leaf extracts to inhibit vascular endothelial growth factor (VEGF)-induced angiogenesis in vitro and in vi...

Nelumbo nucifera leaves extracts inhibit mouse airway smooth muscle contraction

BACKGROUND Alkaloids extracted from lotus leaves (AELL) can relax vascular smooth muscle. However, whether AELL has a similar relaxant role on airway smooth muscle (ASM) remains unknown. This study aimed to explore the relaxant property of AELL on ASM and the underlying mechanism. METHODS Alkaloids were extracted from dried lotus leaves using the high temperature rotary evaporation extraction...
