North East India is a home of tremendous and versatile vegetative oil bearing materials because of the subtropical climatic conditions. Screening, characterization, and domestication of high yielding treeborne oilseeds rich in oleic acid and tocopherol are highly demandable from industrial aspects. As very few studies have been carried out in this regard from this region, our investigation aims to exploit new sources of tree-borne oilseeds rich in omega fatty acids for edible and non-edible purposes from both known and unknown plants. Six lesser-known tree-borne oilseeds were characterized based on oil content, tocopherol composition and metal content. The fatty oil was found more in Dysoxylum procerum (50%). The dominating fatty acid was oleic acid ranged between 38.4 to 64%. The oil of Terminalia bellirica showed high content of tocopherol (0.05%). Among eleven metals (Ca, Cu, Zn, Mg, Mn, Fe, Pb, Cd, As, Na, K) in all the six fatty oil contents, Pb and Cu showed high concentrations as compared to the codex standard while Fe values of all the oil contents were below the permissible concentrations.
由于亚热带气候条件，印度东北部是大量多样的含植物油材料的产地。从工业角度来看，对富含油酸和生育酚的高产木本油料种子进行筛选、特性鉴定和驯化的需求非常高。由于该地区在这方面的研究很少，我们的调查旨在从已知和未知植物中开发富含欧米伽脂肪酸的木本油料种子的新来源，用于食用和非食用目的。基于油含量、生育酚组成和金属含量对六种鲜为人知的木本油料种子进行了特性鉴定。发现长叶地黄连（Dysoxylum procerum）的脂肪油含量更高（50%）。主要脂肪酸为油酸，含量在38.4%至64%之间。毛诃子（Terminalia bellirica）的油中生育酚含量较高（0.05%）。在所有六种脂肪油含量中的十一种金属（钙、铜、锌、镁、锰、铁、铅、镉、砷、钠、钾）中，与食品法典标准相比，铅和铜的浓度较高，而所有油含量中的铁值均低于允许浓度。
