Bivarate models: relationships between solar irradiation and either sunshine duration or extremum temperatures
(Elsevier Science Ltd. www.elsevier.com/locate/renene, 2003)
The Republic of Botswana is one of the sunniest countries in Southern Africa. It has very little cloud cover, insufficient rainfall, very low humidity, and very low wind speed throughout the year for most parts of the ...
Antioxidant activity of prenylated flavonoids from the West African medicinal plant Dorstenia mannii
(Elsevier Science Ireland Ltd. www.elsevier.com/locate/jethpharm, 2003)
The antioxidant activities of three prenylated flavonoids from Dorstenia mannii (6,8-diprenyleriodictyol, dorsmanin C and dorsmanin F)
were compared to the common, non-prenylated flavonoid, quercetin. The prenylated ...
Phenylpropanoid glycosides of Gnidia polycephala
(Elsevier Ltd. www.elsevier.com/locate/phytochem, 2003)
Two phenylpropanoid glucosides, 2-O-b-d-glucosyloxy-4-methoxybenzenepropanoic acid and its methyl ester, together with
syringin and adicardin were isolated from the stem of Gnidia polycephala and characterized by physical ...
