“…It also foamed in aqueous solution and has hemolytic effect and can also bind on cholesterol sites. These properties make saponins present in the plant to exhibit medicinal properties (Sodipo et al, 1991) and this therefore supports the findings in this present study that extracts of the plants may be useful in chemotherapy of mycotic infections which the antimicrobial studies revealed (Ladan et al, 2009). Alkaloids were found present in hexane, ethylacetate and methanol extracts and this can be corroborated with literature reports which indicate that naturally occurring alkaloids and their synthetic derivatives have analgesic, antispasmodic and bactericidal activities (Okwu and Okwu, 2004).…”

The present study reports the screening of phytochemical constituents of the leaf extracts of Hyptis spicigera using hexane, ethylacetate and methanol and the leaf powder of the plant. Qualitative analysis of phytochemical constituents showed the presence of the following secondary metabolites vitannins, carbohydrates, saponins, flavonoids, steroids, alkaloids, quinones, coumarin, terpenoids, resins and cardiac glycosides. The quantitative analysis of total phenolics, alkaloids, saponins, terpenoids and flavonoids carried out using standard protocols revealed the presence of flavonoids (8.82%), saponins (6.23%), terpenoids (16.10%), alkaloids (7.55%) and phenolics (20.75%) respectively. Phenolics showed the highest content (20.75%) while saponins (6.23%) gave the least content. The high content of phenolics in the plant showed that H. spicigera plant may contain antioxidant properties and could be a good source of natural antioxidants. Also, the richness in flavonoids, saponins, alkaloids and terpenoids in this plant can be correlated with its medicinal properties used by traditional herbal healers in Northern Nigeria.

The oil content of brown and white acha seeds was extracted and characterized using the AOAC procedure. Consumption of these grains by people with health-related diseases necessitated this study to authenticate its nutritional values. The physicochemical characterization revealed the two oils to have low oil yields of high quality. Biochemical profiling of the seeds showed that both oils have high concentration of polyunsaturated fatty acids, vitamins A and E and other minor constituents. These results indicate that brown and white acha seeds are excellent sources of healthy nutrients to humans.Â

“…All photosynthetic organisms synthesise vitamin E (Grusak, 1999;Sattler et al, 2004) thus the presence of the vitamin in M. zeyheri seed is not surprising. Ladan et al (2010) point out that Helianthus annuus (Sunflower) and Sesamun indicum (Sesame) seed, both commercial seed oil sources, have a vitamin E concentration of 41.1 mg g )1 and 1.4 mg g )1 , in their respective seed oils; concentrations that are much higher than the 2 lg g )1 vitamin E concentration reported for M. zeyheri seed oil. Vitamin E, in-vivo, is reported to function as a recyclable chain reaction terminator of polyunsaturated fatty acid free radicals that are generated from endogenous oxidation of lipids (Kamal-Eldin & Appelqvist, 1996).…”

Mimusops zeyheri, an indigenous tree widely distributed in sub-Saharan Africa, provides edible fruit. Research on the tree has focused on fruit pulp composition and uses. This study evaluated the nutritional potential of M. zeyheri seed by determining the proximate, fibre and phytate-phosphate content, the amino acid and fatty acid profiles and vitamin E content of the seed. Dry matter, organic matter, crude protein, ether extract and ash constituted 91.1%, 88.3%, 9.3%, 25.6% and 2.8% of the seed mass respectively. Glutamic acid (1.29 g per 100 g) was the most abundant amino acid. Lysine and phenylalanine were low. Calcium (587.4 mg per 100 g) was the most concentrated macro-mineral assayed. Gross energy value was 24.34 MJ kg )1 . Lipid yield was 21.3%. Oleic acid was the most abundant fatty acid. Vitamin E concentration was about 2 lg g )1 . Phytate-phosphate content was 0.03%. Neutral detergent fibre and acid detergent fibre constituted 33.2% and 15.3% respectively. M. zeyheri seed could be exploited as a dietary energy supplement and an oil source rich in oleic acid.
