It was reported in 1930 (2) that exposure to polarized light had been found to induce hydrolysis of starch grains in the mesophyll of living leaves. Similar action on starch grains in vitro has also been observed (1, 3, 6). The present paper gives an account of some experiments on the hydrolyzing influence of polarized light when applied to foliar stomata. In many plant forms the guard cells of...

OBJECTIVE To determine the acetylcholinesterase inhibitory (AChEI) and antioxidant activity of the ethyl acetate and methanol extracts of 12 traditional medicinal plants used in the treatment of neurological disorders. METHODS AChEI activity was determined spectrophotometrically using the Ellman's colorimetric method. Antioxidant activity was carried out by determining the ability of the extr...


 Aims: Several parts of medicinal plants have been known to many health benefits. One those is the Crinum glaucum (CG) bulb. Therefore, this research was undertaken investigate therapeutic role an aqueous extract CG bulb (aeCGb) against lipopolysaccharide (LPS)-induced haematological and hepatic enzyme alterations in male female rat models.
 Study Design Methodology: Twenty-five twen...

BACKGROUND Lannea schweinfurthii, Zanthoxylum capense, Scadoxus puniceus and Crinum bulbispermum are used traditionally to treat neurological disorders. The aim of this study was to evaluate the cytoprotective potential of the four plants, after induction of toxicity using rotenone, in SH-SY5Y neuroblastoma cells. METHODS Cytotoxicity of the plant extracts and rotenone was assessed using the ...

Mycobacterium ulcerans, the etiologic agent of Buruli ulcer, has been detected on aquatic plants in endemic tropical regions. Here, we tested the effect of several tropical plant extracts on the growth of M. ulcerans and the closely related Mycobacterium marinum. M. ulcerans and M. marinum were inoculated on Middlebrook 7H11 medium with and without extracts from tropical aquatic plants, includi...

Objective: Crinum jagus is used in traditional African medicine the treatment of epilepsy, pain and inflammations.
 Methods: Anticonvulsant activity was investigated using picrotoxin (PCT) strychnine (STR) tests experimental paradigm.
 Results: leaf methanol extract (200, 400, 800 mg kg−1) potentiated hexobarbitone-induced sleeping time significantly (p<0.05) shortened duration con...
