摘要

热带树木茎材对植物保护具有重要意义,研究多集中在其叶片和果实上,但对其化学成分的研究较少。本研究旨在定性和定量地分析Gmelina arborea、Tectona grandis和Anogeissus leiocarpus茎材中的植物化学物质。从当地的锯木厂收集新锯的木材,然后磨成细粉的木材样品。粉末状木材样品及其提取物使用标准方法筛选是否存在植物化学物质。定性筛选结果显示,3种植物均含有单宁、皂苷、甾体、黄酮类、生物碱和萜烯等次生代谢产物。结果还表明,黄芪中生物碱(7.5%)、单宁(4.95%)和黄酮类化合物(4.67%)含量最高,青果中皂苷(3.06%)和萜烯(1.45%)含量最高。本研究确定了所选的三种植物具有药用和抗病原菌的工业应用潜力。

Qualitative and quantitative evaluation of the phytochemical constituents of three wood species in Ogun state, Nigeria
Studies on the phytochemicals of the stem wood of tropical trees are scarce, despite its importance to plant protection and preservation as most researches focused on their leaves and fruits. This research work aimed to qualitatively and quantitatively analyze the phytochemicals present in the stem wood of Gmelina arborea, Tectona grandis and Anogeissus leiocarpus. Freshly sawn timbers were collected from a local sawmill and then grounded into finely powdered wood samples. The powdered wood samples and its extracts were screened for the presence or absence of phytochemicals using standard methodologies. The qualitative screening revealed the presence of various secondary metabolites such as tannin, saponin, steroids, flavonoid, alkaoids and terpene in all the three species. The result also showed that Tectona grandis had the highest percentage of Alkaloid (7.5%), Tannin (4.95%), and Flavonoid (4.67%) while Anogeissus leiocarpus had the highest percentage of Saponin (3.06%) and Terpene (1.45%). This study established the fact that the three selected species studied have potentials in the industries for medicinal and anti-pathogenic usages.
