“…The low iodine values for the Gac seed oil were likely due to a high content (60.5%) of the saturated fatty acid, stearic acid, as measured previously by Ishida et al [17]. The low iodine values of Gac seed oil place it in the non-drying oil group [32], and being a saturated oil, it is fairly stable to auto-oxidation.…”

“…For other types of seeds, the oil yield also tends to be higher when the oil is extracted using hexane than when the SC-CO 2 method is used. However, the differences are not usually as great as was observed for the Gac seeds in the present study; Zhao et al [32] reported 24.1% and 27.2% oil yields for radish seeds when extracted by SC-CO 2 and hexane, respectively, and Molero et al [33] reported close values of 36.0% and 38.4% for oil yields from sunflower seeds and 39.3% and 40.1% from grape seeds.…”

Gac seeds are high in oil, but there are few studies on its extraction and characteristics. This study aimed to characterise Gac seeds and investigate the physicochemical properties of Gac seed oil extracted with supercritical carbon dioxide (SC-CO2) and hexane (Soxhlet). The Gac seed kernel accounted for 66.4 ± 2.7% of the seed weight, and 53.02 ± 1.27% of it was oil. The SC-CO2 oil had a higher quality than the Soxhlet oil for important criteria, such as peroxide (0.12 ± 0.02 vs. 1.80 ± 0.01 meq O2/kg oil), free fatty acid (1.74 ± 0.12 vs. 2.47 ± 0.09 mg KOH/g oil) and unsaponifiable matter (33.2 ± 1.5 vs. 52.6 ± 2.4 g/kg) values, respectively. It also had a better colour (light yellow vs. dark greenish brown) and a higher antioxidant capacity measured with the DPPH (52.69 ± 0.06 vs. 42.98 ± 0.02 µmol Trolox equivalent/g oil) and ABTS (2.10 ± 0.12 vs. 1.52 ± 0.06 µmol Trolox equivalent/g oil) assays. However, a higher yield (53.02 ± 1.27 vs. 34.1 ± 0.8%) was obtained for the Soxhlet oil. Unless refined, the oils would not be edible due to their high unsaponifiable matter, but the SC-CO2 oil would need less refining. Alternatively, the high unsaponifiable matter in the oil, especially in the Soxhlet oil, may make it useful for medicinal purposes.

“…Gelmez et al and Lucas et al reported high tocopherol extraction rates, using CO 2 at pressures of 16.4 MPa and 25 MPa, respectively, close to that used in this study. Nimet et al and Zhao et al evaluated the extraction of sunflower and radish seed oil, respectively, and report that the use of supercritical CO 2 favoured the extraction of tocopherols when compared to propane. Furthermore, some studies have shown that the use of supercritical CO 2 is more advantageous than the use of n ‐hexane for the extraction of tocopherols …”

Macauba kernel oil (MKO) was extracted using supercritical CO 2 and compressed propane as the solvent. The influence of temperature (313-353 K for CO 2 and 303-333 K for propane) and pressure (18-22 MPa for CO 2 and 8-12 MPa for propane) on oil yield was investigated, and the results were compared with conventional extraction. A characterization of oil and defatted meal was performed. Temperature and pressure, in the evaluated range, influenced oil yield with the use of CO 2 . For propane, the oil yield was not influenced by the experimental conditions. In the evaluated experimental range, the use of propane and CO 2 provided 100 % and $93 % oil yield compared to conventional extraction, respectively. MKO showed a predominance of saturated fatty acids, among which lauric acid was the major constituent. CO 2 presented greater efficiency in the removal of phytosteroids and tocopherols from the macauba kernel, however, the oil extracted with propane presented longer oxidative stability. Defatted meals presented modified physico-chemical composition and potentiated technological characteristics due to oil removal.

Vegetables have great significance and importance as they are not only useful as food but on the other hand, vegetables are a vital source in the treatment and prevention of various ailments, a powerful source of minerals, vitamins, antioxidants, fibers, and amino acids, therefore, help to buildup and heal the body. Mainly concerning cruciferous vegetables, have been famous for marked effects of cardio-protective, antimicrobial, and anti-carcinogenic. The environments of Pakistan are amicable for vegetable production. Raphanus sativus generally named radish is a widespread plant all over the world belongs to the Brassicaceae family. Edible R sativus L. Var. caudatus are green color seed pods, utilized for properties attributed to Raphanus. Different chemical constituents are identified from radish. Various researches show that the whole radish plant has significant pharmacological activity. The current review expands ontypes, phytochemical components, and pharmacological potential and toxic outcomes of the radish plant Keywords: Radish, varieties, constituents, pharmacology, uses, toxicity
