Possibility of converting indigenousSalvadora persicaL. seed oil into biodiesel in Pakistan

Abstract

In this research study biodiesel has been successfully produced from vegetable seed oil of an indigenous plant Salvadora persica L. that meets the international biodiesel standard (ASTM D6751). The biodiesel yield was 1.57 g/5g (31.4% by weight) and the in-situ transesterification ester content conversion was 97.7%. The produced biodiesel density was 0.894 g/mL, its kinematic viscosity 5.51 mm 2 /s, HHV 35.26 MJ/kg, flash point 210 o C, cetane no. 61 and sulphur content 0.0844 %. Thermal analysis of the biodiesel showed 97% weight loss was achieved at 595°C with total oxidation of the biodiesel. The production energy efficiency was 0.46% with a lab scale setup, assuming the volume fraction ratio (volume of the sample/ total volume of the equipment used). The results revealed that single step in-situ transesterification method is suitable for the production of biodiesel from Salvadora persica seed oil.

HPLC/MSn Profiling and Healing Activity of a Muco-Adhesive Formula of Salvadora persica against Acetic Acid-Induced Oral Ulcer in Rats

“…Palmitic and oleic acids were the major fatty acids detected; both were identified previously in the stems and roots of S. persica [ 34 ]. Myristic acid (36), hydroxy octadecenoic acid (37), hexadecenoic acid (3), arachidic acid (40), linoleic acid (41), heptadecenoic acid (44) and stearic acid (54) were detected previously in the stems and roots of S. persica [ 23 , 34 ], while linolenic acid (35) was detected previously in the seed oil of S. persica [ 35 ]. Hydroxytetradecanoic acid (33), hydroxyhexadecanoic acid (34), hydroxyoctadecanoic acid (45), nonadecenoic acid (51) and hydroxyeicosanoic acid (53) were detected in this plant for the first time.…”

Salvadora persica L.: Toothbrush tree with health benefits and industrial applications – An updated evidence-based review

“…The ability of S. persica root powder as a green bio sorbent for barium and strontium purification from wastewater and radioactive wastes have recently been examined by ( Hassan et al, 2020 ). In addition, ( Ali et al, 2018 ) have recently succeeded in converting vegetable seed oil of S. persica into biodiesel that satisfy the international biodiesel standard [ASTM D6751].…”
