“…El sobrenadante fue pasado a través de papel filtro (Whatman No. 2) para remover los restos del polvo de la planta y el solvente fue evaporado en un extractor tipo Soxhlet a 85°C (Pesewu et al 2008). Se hicieron dos alícuotas; una de ellas fue utilizada para determinar la composición química del extracto y otra para evaluar la actividad antimicrobiana.…”

“…Plant secondary metabolites are known to possess antimicrobial and antioxidant properties, and some of them are categorized as generally recognized safe substances (Proestos et al, 2005). With the growing interest in these compounds, phytocompounds from therapeutic plants with some biomedicinal activity are in great demand (Chen et al, 2008;Pesewu et al, 2008;Prachayasittikul et al, 2008).…”

Abstract:The aim of this review was to explore the pharmacological activity of early tracheophytes (pteridophytes) as an alternative medicine for treating human ailments. As the first vascular plants, pteridophytes (aka, ferns and fern allies) are an ancient lineage, and human beings have been exploring and using taxa from this lineage for over 2000 years because of their beneficial properties. We have documented the medicinal uses of pteridophytes belonging to thirty different families. The lycophyte Selaginella sp. was shown in earlier studies to have multiple pharmacological activity, such as antioxidant, anti-inflammatory, anti-cancer, antidiabetic, antiviral, antimicrobial, and anti-Alzheimer properties. Among all the pteridophytes examined, taxa from the Pteridaceae, Polypodiaceae, and Adiantaceae exhibited significant medicinal activity. Based on our review, many pteridophytes have properties that could be used in alternative medicine for treatment of various human illnesses. Biotechnological tools can be used to preserve and even improve their bioactive molecules for the preparation of medicines against illness. Even though several studies have reported medicinal uses of ferns, the possible bioactive compounds of several pteridophytes have not been identified. Furthermore, their optimal dosage level and treatment strategies still need to be determined. Finally, the future direction of pteridophyte research is discussed.

“…Various diseases including cancer and Alzheimer's disease had been reported to be treated with active compounds from plants (Kumar et al, 2009;Sheeja and Kuttan, 2007). Researches on phytochemical analyses of plant extracts in most cases correlate the chemical constituents of the plants with their pharmacological activity (Prachayasittikul et al, 2008;Costa et al, 2008;Al-Bayati and Al-Mola, 2008;Chen et al, 2008;Pesewu et al, 2008;Turker and Usta, 2008;Nyamai et al, 2016).…”

The phytochemical constituents of stem bark extracts of Khaya senegalensis were isolated and analyzed using Gas Chromatography-Mass Spectrometry (GC-MS). A shade-dried stem bark of K. senegalensis was extracted using methanol and water as solvents. The main chemical compositions of the extracts were analyzed by GC-MS and preliminary phytochemical analysis was performed to confirm the various classes of active chemical. The chemical composition of methanolic stem bark extract of K. senegalensis included: 4-Hepten-3-one, 2, 6-Pyridinedicarboxylic acid, 3-O-methyl-d-glucose, myristic acid, pentadecanoic acid, n-Hexadecanoic acid, 9, 12-Octadecadienoic acid, and 11-Octadecenoic acid. Others are 9-Hexadecenoic acid, Stearic acid, I, E-11, Z-13-Octadecatriene, Cyclododecyne, Hexadecanoic acid, Ricinoleic acid, 13-Decosenoic acid, and 9-Hexadecenal. The Chemical composition of aqueous stem bark extract of K. senegalensis included 1, 2, 3-benzenetriol, n-Hexadecanoic acid, oleic acid, (Z)6,(Z)9-pentadecadeien-1-ol, 1,E-11,Z-13-octadecatriene, and 1-flourodecane. Other chemical constituents of the aqueous extract included 9-octadecanal, E-9-tetradecanal, and 2-methyl-Z, Z-3, 13-octadecadienol. The molecular weight of these compounds ranged from low to high with carbon skeleton of between C 7 and C 37 . Both aromatic and aliphatic compounds were identified . K. senegalensis contains alkaloid, saponin, tannins and flavonoids. A good number of bioactive compounds were present in the stem bark of K. senegalensis.
