“…The values of moisture content, ash, crude protein, crude fat, crude fibre and carbohydrate ranged 8.1-8.9%, 8.4-9.0%, 14.3-15.3%, 1.4-2.1%, 16.9-18.2% and 47.1-49.4%, respectively. The values obtained for the moisture contents of okra calyx flour were lower than that of okra seed flour of 10.38%, 13.99% and 9.27-12.70% reported by Adelakun et al (2009), Soares et al (2012) and Habtamu et al (2018), respectively. However, the moisture content of 5.52% and 6.31% reported for okra flour by Ndamitso et al (2012) and Ukegbu and Okereke (2013) were lower than that obtained for okra calyx flour.…”

Purpose Calyx of okra pods is usually cut off and discarded as a waste during processing, whereas the pulp and seeds are being used. This study aims to investigate the nutrient composition and anti-nutritional properties of okra calyx flour. Design/methodology/approach Calyces from four varieties (Ex-kwadon, Solar, Chalawa and Syria) of okra pods were processed into flour. The proximate composition, mineral content, vitamin content and anti-nutritional composition of the flour samples were analysed by using standard methods. Findings There were significant differences in moisture content (p = 0.012), crude fat (p = 0.001), crude fibre (p = 0.002), carbohydrate (p = 0.002), sodium (p < 0.001), magnesium (p < 0.001), iron (p < 0.001), zinc (p = 0.006), vitamin A (p < 0.001) and vitamin C (p = 0.001) contents of okra calyx flour. The values of proximate composition ranged 8.1-8.9%, 8.4-9.0%, 14.3-15.3%, 1.4-2.1%, 16.9-18.2% and 47.1-49.4% for moisture content, ash, crude protein, crude fat, crude fibre and carbohydrate, respectively, whereas the values of mineral contents ranged 7.6-8.7 mg/100g, 35.7-41.2 mg/100g, 26.5-28.1 mg/100g, 93.2-95.8 mg/100g, 1.6-1.8 mg/100g and 5.2-5.7 mg/100g for sodium, magnesium, potassium, calcium, iron and zinc, respectively. The values of vitamin contents of okra calyx flour ranged 0.2-0.3 µg/100g, 7.1-8.9 mg/100g and 0.1-0.2 mg/100g for vitamin A, vitamin C and thiamine contents respectively. Also, there were significant differences in the values of phytate (p = 0.023), oxalate (p = 0.011) and saponin (p < 0.001) contents with the values of anti-nutritional properties ranging 1.3-1.5 mg/100g, 2.5-3.3 mg/100g, 7.4-9.7 mg/100g and 2.3-3.6 mg/100g for tannin, phytate, oxalate and saponin contents, respectively. Research limitations/implications There are scanty published works/information on proximate composition, mineral content, vitamin content and anti-nutritional composition of okra calyx flour. Practical implications The study showed that okra calyx flour could be useful in fortification/supplement of carbohydrate-based foods in food system. Originality/value Okra calyx flour comprises high crude fibre, crude protein, ash and vitamin C contents. Also, calcium is the major mineral content of okra calyx flour followed by magnesium and potassium. However, the tannin content reported higher in okra leaf flour, and okra flour is low in okra calyx flour.

“…The fiber content of okra seed of local variety was 29.54%. Similarly, the fiber content of okra seeds was studied in the study of Soares et al (2012). The percentage of fiber in the okra seeds was reported as 30.81%, which was greater than the fiber content calculated in the present study.…”

“…About 20-40% of oil is produced from okra seeds (Gemede et al, 2015). The quantity of oil depends on seed variety, climate conditions, temperature and extraction method, for example the locally developed Pakistani variety (Sabz Pari) had lower oil content i.e., 11.72% (Soares et al, 2012). In brief, okra has functional and nutraceutical properties.…”

The current study was held in University of Agriculture, Faisalabad. Vegetable and oil related research sections were used to evaluate different parameters of this study. The antihypercholesterolemic effect of okra (Abelmoschus esculentus) seed oil was studied by efficacy trials on Sprague Dowley rats. Materials and protocols used in this study are as follows: 2.1 Attainment of raw material The seeds of local variety of okra named "sabaz pari" were purchased from Ayub Agriculture Research Institute, Faisalabad.

Free fatty acid, peroxide value , conjugated diene and triene, chlorophyll, β-carotene, fatty acid composition, triglyceride, tocol (tocopherol and tocotrienol) compositions, sterol, wax and total polymeric compound amounts of cold pressed Ficus carica seed oil were evaluated by using chromatographic and spectrometric methods in this study. While the % free fatty acid of cold pressed ficus carica seed oil was 0.76±0.06, the peroxide value was found as 1.06 ± 0.09 meqO2/kg. It also had low content of conjugated diene and triene amounts, chlorophyll, wax and total polymeric compounds. The obtained results demonstrated that cold pressed ficus carica seed oil had rich linolenic and linoleic acid, and contained high amounts of Linoleic- Linolenic- Linolenic, Linolenic- Linolenic- Linolenic, Olenic- Linoleic– Linolenictriglycerides. Cold pressed ficus carica had a high content of β-carotene (4114.9 ppm), total tocol (1006 ppm) and sterol (7250.83 ppm). The obtained results showed that ficus carica seed oil is a product with superior properties due to its high nutritional value and beneficial phytochemicals. Therefore this oil can be an alternative to vegetable oils and used as a medical product.
