Effect of Supercritical Fluid Extraction Process on Chemical Composition of Polianthes tuberosa Flower Extracts

Abstract

Supercritical fluid extracts from flowers of Polianthes tuberosa var. double were ob tained using carbon dioxide as a solvent. Yield extract obtained was 2.5%. The effects of the pressure process (18 MPa, 28 MPa, and 38 MPa) and temperature process (313 K, 323 K, and 333 K) on the volatile composition of tuberose flowers extracts were evaluated, and a significant variation in chemical composition was found. Characteristic compounds of tuberose as methyl isoeugenol, benzyl benzoate, methyl anthranilate, pentacosene, and heptacosene were obtained mainly at 18 MPa and 333 K process conditions, and could be used in the perfume or fragrance industry. Components such as geraniol, farnesol, and methyl eugenol were also obtained, these extracts could be used in the development of cosmeceutical products. This work allowed to identification of the chemical composition profile and evaluation of the changes in tuberose extracts due to the extraction process.

Phytochemical analysis of UV active and inactive bioactive compounds present in Polianthes tuberosa (Linn.) flower

“…The GC-MS analysis of the extracts obtained from the ovary, petal, and stamens showed the presence of additional phytochemicals such as piperonal, vanillin, [14] used a supercritical extraction procedure to identify the photo components from the flower of P. tuberosa by GC-MS. The authors reported the presence of 37 compounds, mainly volatile compounds like terpenes, hydrocarbons, alcohols, and esters from the whole flower.…”

Green Separation and Extraction Processes: Part I

“…Supercritical fluid extraction comprises a known technology applied to obtain volatile compounds from flowers, i.e., tuberose (belonging to the Asparagaceae family), that could be used for example in the perfume or fragrance industry [1]. The cocoa shell-a residue of low commercial value-represents an alternative for obtaining substances of added value for the food and pharmaceutical industry, including fat, theobromine and caffeine [2].…”
