In recent times, medicinal plants are being greatly used ethnomedicinally for the management and treatment of diseases and health conditions. One of such medicinal plants is Tithonia diversifolia. This study aimed at determining the phytochemical, elemental and proximate content of the powdered plant part to help infer what is responsible for the reported therapeutic characteristics of the plant as well as determine the quality, purity and safety profile of the plant. Leaves of T.diversifolia were subjected to phytochemical, proximate and mineral screening using standard laboratory procedures. Qualitative phytochemical observation revealed the presence of Tannins, saponins, flavonoids and terpenoids. Crude Protein content was the highest with 27.69% followed by Crude Fibre (14.89%), Ash (13.86%), Moisture Content (10.92%) and the least value 1.14% for Fat. Magnesium (Mg) content was highest with 6712.50mg/kg which is 22, 35, 122 & 144 times higher than the content of Iron (Fe) (291.5mg/kg), Manganese (Mn) (191.0mg/kg), Zinc (Zn) (54.9mg/kg) and Copper (Cu) (15.1mg/kg). However, elements (heavy metals) Lead (Pb), Cadmium (Cd), Chromium (Cr) and Cobalt (Co) were not detected. Results obtained in the study is indicative of a potential drug substitute which can be used to help manage and treat diseases due to the phytochemicals, nutrients, and minerals present in them. Also, the safety indices of this plant part have been established, thus, information obtained from the study can serve as a reference standard for the plant monograph.

Sage plants (Salvia officinalis L.) were dried in the passive dryers in different times of the year. Different passive solar dryers were used to achieve the socio-economical benefits from drying the medicinal plants growing in Sinai area. Drying sage plants might be a source to increase the Bedouin income instead of cannabis or marijuana, especially if it is exported abroad. Four drying methods were used in this investigation to dry sage in two seasons, namely August 2009 and March 2010 before flowering stage. Plants were dried in an Unglazed transpired passive solar dryer with 100% exposure to direct sun-rays, in a greenhouse dryer covered with shading cloth with 50% exposure to direct sun-rays, and with 0% sun-rays while the medicinal plants were protected from sun i.e. in shaded barn. Investigations were carried out under the environmental weather conditions of Ismailia, Egypt. The study revealed that sage can be dried at different times of the year even before the flowering stage of the plants.
