“…A significant variability was found in the oil content of studied castor seed varieties that ranged from 44-48%. The obtained values showed less oil content than indigenous variety reported earlier [18]. Observed variations in the seed oil content may be due to castor seed genotypes, harvesting time, environmental and cultural aspects.…”

Introduction. This paper provides the complete profile of physicochemical properties and fatty acid composition of local castor varieties from Sindh, Pakistan. Initially, physical characteristics of seeds were studied followed by detailed examination of oil. Materials and methods. Oil was extracted through Soxhlet extraction method followed by physico-chemical examination of necessary parameters (iodine value, peroxide value, saponification value, viscosity and moisture). For qualitative analysis of castor oil GCMS and FTIR instruments were used. Results and discussions. Oil content was observed in the range of 44-48%. Moisture and ash content of castor seeds were found to be 4.22-5.16% and 5.66-6.49%, respectively. Compositional analysis by GCMS has shown ricinoleic acid (88.5-93.1%) as a prominent fatty acid in all local varieties. Other fatty acids present were palmitic (0.4-0.8%), stearic (0.8-1.0%), linoleic (2.8-3.3%), and ecosenoic (0.2-1.5%). Free fatty acid value of all castor oil varieties was found to be in the range of 0.16-0.53%. Other quality parameters such as IV, PV and SV of different castor oil varieties were determined in the range of 79.16-90.03 gI2/100g, 1.62-1.89 meq/Kg, and 188.12-204.76 mgKOH/g, respectively. The FTIR spectra of castor seed oil varieties were nearly similar. On careful examination of the intensity values of each functional group present in the oil showed some variations in castor seed varieties. Conclusion. Indigenous local varieties of castor with sufficient oil content (> 40%) were explored and examined for some important parameters. FTIR band intensities of some functional groups highly correlated with important parameters of castor oil.

“…With extraction of castor oil using n-hexane, the oil content vary from 34.6 to 56.6% (Panhwar et al, 2016;Sbihi et al, 2018;Severino et al, 2015). This variation may be attributed to changes in climatic conditions, geographical location, and type of variety (Severino et al, 2015).…”

“…Table 2 shows that the percentage of ricinoleic acid in castor oilseed from India, China, Brazil, Ethiopia, Pakistan, Saudi Arabia, Nigeria, and Tanzania were 87.3, 90.85, 88.2, 91.06, 94.59, 75.77, 86.96, and 87.8%, respectively. The ricinoleic acid in castor oil from Pakistan was the highest with 94.59% whereas Saudi Arabia was the least with 75.77% (Panhwar et al, 2016;Sbihi et al, 2018). Researchers have shown that ricinoleic acid is present in the endosperm and cotyledon of immature castor seed but not in developed male flowers (Brown et al, 2012).…”

“…Therefore, low acid value is a good indicator of vegetable oil and could be valuable for refining process. A number of reported acid values in castor oil ranges from 0.14 to 1.97 mg/g oil (Omari et al, 2015;Panhwar et al, 2016;Perdomo et al, 2013;Yusuf et al, 2015). Castor oilseeds planted in Nigeria had high acid values of 14.80 and 15.57 mg/g oil (Nangbes et al, 2013;Omohu & Omale, 2017), but this could be associated to the poor handling and processing of the seed.…”

“…The fatty acid profiles present in castor oil are ricinoleic, oleic, stearic, palmitic, linoleic, linolenic acid and among others. Among them, ricinoleic acid, a monounsaturated fatty acid is the dominant acid constituting about 75 to 90% of the total oil composition (Beruk et al, 2018;Panhwar et al, 2016;Yusuf et al, 2015). It is worth saying that, the castor oil is the sole oil with such a high amount of fatty acid and this makes it unique from other vegetable oils.…”
