Ethnopharmacological relevanceCulinary herbs and spices are widely used ethnomedically across Africa. They are traditionally employed in the treatment of several ailments including inflammation disorders, pain alleviation and infectious diseases. Pharmacological studies are necessary to provide a scientific basis to substantiate their traditional use and safety. In this study, the 15-lipoxygenase inhibitory, antioxidant, antimycobacterial and the cytotoxic activities, total phenolic and flavonoid contents of fourteen edible plants were investigated. Materials and MethodsThe 15-lipoxygenase inhibitory activity was evaluated by the ferrous oxidation-xylenol orange (FOX) assay method. The antioxidant activity was determined using free-radical scavenging assays. The antimycobacterial activity was determined by a broth microdilution method against three species of mycobacteria: Mycobacterium smegmatis, Mycobacterium aurum and Mycobacterium fortuitum using tetrazolium violet as growth indicator. The cytotoxicity was assessed by the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay on Vero monkey kidney cells. ResultsAll the extracts tested had some 15-lipoxygenase inhibitory activity ranging from 32.9-78.64%.Adansonia digitata (fruit) had the highest antioxidant capacity (IC 50 values of 8.15 μg/mL and 9.16 μg/mL in the DPPH and ABTS assays respectively; TEAC of 0.75 in the FRAP assay) along with the highest amount of total phenolics (237.68 mg GAE/g) and total flavonoids (16.14 mg QE/g). There were good correlations between DPPH and ABTS values (R 2 0.98) and between total phenolics and total flavonoids (R 2 0.94). Tamarindus indica had significant antimycobacterial activity against M. aurum (MIC 78 μg/mL). As could be expected with edible plants, all the extracts had a relatively low cytotoxicity with LC 50 values higher than 102 μg/mL with the exception of the two Aframomum species (33 and 74 μg/mL). 2 ConclusionsThis study provides scientific support for some of the the traditional uses and the pharmacological activities of the culinary herbs and spices investigated. The results suggest that increasing intake of some of these herbs may be useful in preventing or reducing the progression of lifestyle-related diseases. The diversity of the pharmacological activities of the extract from the fruit of Adansonia digitata suggested that this plant might be valuable for application in human and animal health.

“…Vitamin E homologues (tocopherols) naturally present in TNO contribute to increasing the oil's shelf life due to their antioxidant properties . Jing et al claimed that in vitro studies into the antioxidant capacity of TNO indicated that its radical scavenging ability was equal to that of vitamin C. However, this work ignored the fact that lipids are not soluble in water, and ignored the fact that the active antioxidants were minor components in the oil. Hydroxyl radicals are the most active and toxic free radicals and thus hydroxyl scavenging ability was used as an indicator of antioxidant activity although this work ignored the lack of selectivity of hydroxyl radicals.…”

“…In addition to tocopherols, other classes of compounds that comprise the unsaponifiable fraction in TNO include phytosterols, polyphenols and possibly carotenoids . The most abundant phytosterol class (about 90%) in TNO was identified to be 4‐desmethyl sterol and its dominant component was β‐sitosterol at 50.4% .…”

Despite its high nutritional value, tiger nut oil is hardly used in food industries compared to other vegetable oils such as olive and peanut oil. However, its benefits are increasingly being recognized, including its stability and similarity to olive oil in particular. This review discusses its composition, physico‐chemical properties and economic potential. Literature reveals that tiger nut oil shares a similar fatty acid profile with olive, avocado and hazelnut oil. Its low content of polyunsaturated fatty acid, tocopherol and phytosterol contributes to its high stability. When compared to soy bean oil, its phospholipids composition (3.1–5.4%) is higher. Its iodine and acid values reflect its quality at 76.60 and 0.03 mg KOH/g oil, respectively. Roasted tiger nut oil was found to contain vanillin and to a lesser extent 2, 3‐dihydro‐3, 5‐dihydroxy‐6‐methyl‐4H‐pyran‐4‐one and 5‐ethylfurfural as key odorants contributing to the overall aroma of the oil. Its low viscosity makes it suitable for use in coating industry and as fuel. In‐depth studies on the oils' constituents are on‐going but efficient and environmentally friendly extraction techniques are needed. Based on the available data, tiger nut oil has been established as an oil of good nutritional value which may be exploited to the great benefit of growers, processors and dealers of the tuber. This review discusses the composition, physico‐chemical properties and economic potential of tiger nut oil.

The objective of the present study was to evaluate the antioxidant activity, antitumor effect, and antiaging property of proanthocyanidins from Kunlun Chrysanthemum flowers (PKCF) grown in Xinjiang. In vitro antioxidant experiments results showed that the total antioxidant activity and the scavenging capacity of hydroxyl radicals (•OH) and 1,1-diphenyl-2-picrylhydrazyl (DPPH•) radicals increased in a concentration-dependent manner and were stronger than those of vitamin C. To investigate the antioxidant activity of PKCF in vivo, we used serum, liver, and kidney from mouse for the measurement of superoxide dismutase (SOD), malondialdehyde (MDA), and total antioxidant capacity (T-AOC). Results indicated that PKCF had antioxidative effect in vivo which significantly improved the activity of SOD and T-AOC and decreased MDA content. To investigate the antitumor activity of PKCF, we used H22 cells, HeLa cells, and Eca-109 cells with Vero cells as control. Inhibition ratio and IC50 values were measured by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay; PKCF showed great inhibitory activity on H22 cells and HeLa cells. We also used fruit flies as a model for analyzing the anti-aging property of PKCF. Results showed that PKCF has antiaging effect on Drosophila. Results of the present study demonstrated that PKCF could be a promising agent that may find applications in health care, medicine, and cosmetics.
