Incidence of cancer is growing swiftly worldwide and sparse supply of anticancer drugs; unaffordable cost and its lethal effect have shown the way to adopt complementary and alternative medicine for the treatment and/or prevention of cancer. The isolation of anti-cancer alkaloids vinblastine, vincristine and podophyllotoxins during 1950s prompts research on anticancer agents from plant origins....

Antioxidant activities of the ethanol (90%) extract of seeds of Lawsonia inermis L., as well as chloroform, ethyl acetate and water fractions extracted from the 90% ethanol extract were examined by a DPPH free radical scavenging and ferric reducing power (FRPA) as Non-site specific assays and lipid peroxidation (TBARS) as site specific assay. The 90% ethanol extract and its fractions along with...

Nonsteroidal and steroidal drugs are generally used to treat inflammation. However, these drugs have side-effects like nausea, vomiting, etc. This lead to search for new anti-inflammatory agents from natural sources, which would be effective and safe.

Its leaves are used as a folk medicine for the treatment of external hemorrhage and fingernail abscesses. Investigation of the ethyl acetate (EtOAc)-soluble fractions from methanol extract of the aerial part of Lawsonia inermis has le...

The antioxidant activity of several Malaysian plant extracts was analyzed simultaneously with their pro-oxidant capacity. This ratio represents an index (ProAntidex) of the net free radical scavenging ability of whole plant extracts. We observed that ethanolic extracts of Nephelium lappaceum peel, Fragaria x ananassa leaf, Lawsonia inermis leaf, Syzygium aqueum leaf and grape seed had a lower P...
