Phenolic compounds from the stems of Zea mays and their pharmacological activity (original) (raw)

A new flavonol glycoside from the seeds of Zea Mays

Indian Journal of Chemistry Section B-organic Chemistry Including Medicinal Chemistry, 2006

The flavonol glycoside, together with known compound quercetin has been isolated from the ethyl acetate extract of methanolic extract of the seeds of locally grown Zea Mays. The two isolated flavonoid compounds been have identified on the basis of UV, IR, 1 HNMR, 13 C-NMR, COSY, DEPT 45, DEPT 90, DEPT 135 and mass spectral data.

Phytochemicals screening and total phenolic content of Malaysian Zea mays hair extracts

international food research journal, 2012

In the present study, Malaysian Zea mays hair extracts are screened for the occurrence of bioactive compounds. The results positively showed the present of flavonoids, saponin, tannins, phlobatannins, phenols, alkaloids and cardiac glycosides in both aqueous and methanolic extract of Zea mays hair. Terpenoid compounds however present only in the methanolic extract sample. In addition, the total phenolic content (TPC) in aqueous extract was significantly higher (42.71 + 0.87 µg/g of tannic acid equivalent (TAE)) compared to methanolic extract (40.38 + 1.10 µg/g of TAE). The findings suggested that phytochemicals present in Zea mays hair are potentially beneficial as therapeutic and antioxidative agents in pharmaceuticals, food and other related industries.

Analgesic and anti-inflammatory activities of Zea mays leaves

Background & Aim: Zea mays leaf used traditionally in Ibibio ethno medicine in Southern Nigeria to treat malaria and other inflammatory diseases. These anti-inflammatory and analgesic properties were evaluated against experimentally induced inflammation and pains using standard models. Experimental: The effects of ethanol leaf extract of Zea mays (170-510 mg/kg) on experimentally induced inflammation and pain were studied in rats using Carrageenin, egg albumin and xylene-induced inflammation as well as acetic acid-induced writhing and thermal induced pain models. The GCMS analysis of the most active fraction was carried out. Results: The extract (170-520 mg/kg) inhibited inflammation and pains caused by different phlogistic agents used in a dose dependent fashion. The various degrees of inhibitions were statistically significant (p<0.05, 0.01, 0.001), though incomparable to that of the standard drugs used (ASA and indomethacin). The GC-MS revealed the present of polyunsaturated f...
