IDENTIFICATION OF NOVEL NATURAL MOLECULE FROM METHANOLIC STEM BARK EXTRACT OF PARKINSONIA ACULEATAAbstract
Parkinsonia aculeata (family – Caesalpiniaceae) is a large spinous shrub found in warmer regions of the world. It is a well known medicinal plant that has significant and promising biological activities such as antioxidant, anti-inflammatory, antidiabetic, antispermatogenic, etc. The phytochemical investigations of the leaves, flowers, and stem have revealed the presence of various glycosides, flavonoids, reducing sugars, alkaloids, sterols, tannins, volatile oils, and saponins. The various biological activities and potent phytoconstituents of the plant indicate its therapeutic potential efficacy. The present study shows the detailed investigation of the methanolic stem bark extract of the title plant. From the methanolic stem bark extract of the title plant 1-cyclohexyltridec-1-ene (new compound A), 6-hydroxypentacosylpentanoate (B), α-amyrin acetate (C), α-amyrin (D) and β-sitosterol (E) were isolated with the help of column chromatographic technique and characterized on the basis of different spectral studies i.e., 1H NMR, 13C NMR, IR, and Mass spectro-scopy.
