Isolation, Identification and Characterization of Ximenynic Acid with Anti-Aging Activity from Santalum Album

Medicinal plants and its products have been used as a remedial agent in most irising countries for treating diseases. Furthermore, an increasing reliance on the use of medicinal plants in industrialized societies has been traced for the extraction and development of several drugs and chemotherapeutics from these herbal plants. Novel acetylenic fatty acids named Ximenynic acid (XMA) were successfully isolated from the seeds of Santalum album L by N-Hexane extraction. Ximenynic acid (or Santalbic acid) is one of the few acetylenic fatty acids occurring at higher levels in plant seed oils. Ximenynic acid predominantly exists in the seed oil of Santalaceae, Olacaceae, and Opiliaceae families. The structure of XMA was characterized by UV-visible spectroscopy, Infrared Spectrum (IR), NMR Spectroscopy, Differential scanning calorimetry (DSC), Thermal Gravimetric Analysis (TGA), X-ray diffraction (XRD), Fourier Transform Infrared Spectroscopy (FT-IR), LCMS spectral analysis. The antiaging activities were assessed by anti-collagenase enzyme assay. Structural analysis revealed that XMA was a crystalline material with a melting point of 38.25◦C and an averagemolecularweight of 278 kDa. Which is composed of carboxylic acid, butylenic acid, methylene, allylic in their structure. The antiaging assay showed that XMA exhibited signi icant collagenase inhibition activity as compared with Catechin. These indings suggested that the acetylenic fatty acids XMA could be served as a novel antiaging in Pharmaceutical as well as the cosmetic industry.
