“…Leaf of Cleome gynandra consumed as leafy vegetable has anti-inflammatory and lysosomal stability actions [ 50 ], potent dose-dependent anticancer activity comparable to that of 5-fluorouracil [ 51 ] and free radical scavenging activity [ 52 , 53 ]. It is also believed to improve eyesight and provide energy [ 33 ].…”

Many of the plant species that are cultivated for food across the world are neglected and underutilized. To assess their diversity in Benin and identify the priority species and establish their research needs, a survey was conducted in 50 villages distributed throughout the country. The study revealed 41 neglected and underutilized crop species (NUCS) among which 19 were identified as of priority base on 10 criteria among which included their extent and degree of consumption. Reasons for neglect vary with the producers and the agricultural technicians. Market surveys revealed that NUCS are important source of household incomes and substantially contribute to poverty reduction. Review of the literature available revealed that most of the species are rich in nutrients and have some proven medicinal values and the promotion of their use would help in combating malnutrition and improving the health status of the local populations. The knowledge gaps and research needs are immense on most of the species identified as no concrete scientific data is nationally available. In terms of research, almost all has to be done starting from basic ethnobotanical investigation. The results will help the scientists and students willing to conduct research on NUCS in Benin to better orient their research programs.

“…Antioxidant characteristics of B. pilosa and its fractions and compounds are determined by the measurement of free radical scavenging activity which was exhibited by the crude extract, ethyl acetate, butanol and water fractions of B. Pilosa. 116,118,138 The compounds heptyl-2-O-ylofuranosyl-(1-6)--glucopyranoside, 3-O-rabinobioside, quercetin 3-O-rutinoside, chlorogenic acid, 3,4-di-O-caffeoylquinic acid, 3,5-di-O-caffeoylquinic acid, 4,5-di-O-caffeoylquinic acid, jacein and centaurein all showed free radical scavenging properties [116]. It is interesting to note that the butanol and ethyl acetate fractions are more diligent than the crude extract and the water fraction of B. pilosa [116].…”

“…Therefore, many researchers have taken interest in analysing and quantifying methanol extract of B. pilosa for antioxidant activity, phenolic content and the phenolic profile and the phenol content was reported as 1102.8±2.2 mg/g. 102,138 Essential oils and monoterpenes of B. pilosa flowers and leaves have antioxidant properties with the leaves possessing the maximum activity. 118 On the whole, phenolics and essential oils found in B. pilosa are considered to be antioxidant compounds of utmost importance.…”

Ageratum conyzoides L., Tridax procumbens L. and Bidens pilosa L. are well known plant species of the Asteraceae family that are considered weeds in intensive agriculture. These weeds are traditionally known to have medicinal properties and have been used for therapeutic treatments. However, it is only the lack of proper knowledge, awareness and screening that have limited their use in pharmaceutical sectors. This review attempts to consolidate the traditional, phytochemical and pharmacological studies that have been carried out on Ageratum conyzoides L., Tridax procumbens L. and Bidens pilosa L., which we note are widely spread throughout the world. This study was conducted through a coherent search on Ageratum conyzoides L., Tridax procumbens L. and Bidens pilosa L. with respect to traditional uses, phytochemical and pharmacological studies that have been performed on these three agricultural weeds all over the world. An exploration of reported descriptions of the potential medical importance of three agricultural weed species (A. conyzoides, T. procumbens and B. pilosa) has been presented. The present review would encourage further clinical investigations into these three plants and their extracts to more closely define the range of uses of these herbs for clinical applications. This, in turn, would give a clear understanding whether these weed species might be targeted to be conserved in a sustainable manner rather than eradicated.

“…African leafy vegetables (ALVs) have been recognised as essential contributors of a balanced diet [3] as well as functional foods as they provide health beyond the basic nutritional requirements [4]. As such Cleome gynandra (spider plant) is an African green leafy vegetable that is consumed in various African countries such as Botswana [5], Ghana [6], Kenya [7], Namibia [8], South Africa [4], Tanzania [9] and Zimbabwe [10]. It has been utilised traditionally to treat stomach aches, headaches [11], ear diseases [12], food poisoning, rheumatism, sexual asthenia, antibacterial infections and snake bites [13].…”

“…It has been utilised traditionally to treat stomach aches, headaches [11], ear diseases [12], food poisoning, rheumatism, sexual asthenia, antibacterial infections and snake bites [13]. Some studies have also shown its ability to act as an antioxidant [14], [15], [13], [16], [10], [4] while some have shown its antibacterial properties [17], [18]. Such health benefits could be attributed to its phenolic composition that has been reported in earlier studies [13], [19], [20], [21], [22], [23].…”

Abstract-Cleome gynandra is an underutilised leafy vegetable that has a high nutritive value and contains phenolic compounds that are essential in reducing or preventing the occurrence of chronic and infectious diseases. Cooking and drying of the vegetable may induce changes to the vegetable's phenolic content, antioxidant and antibacterial activity. C. gynandra was subjected to boiling, steaming, blanching and drying processes and analysed for its Total Phenolic Content (TPC), Total Flavonoid Content (TFC), antioxidant and antimicrobial activity as well as Fourier transform infrared spectroscopy (FTIR). Cooking and drying significantly (p < 0.05) increased the levels of phenolic compounds and antioxidant activity in the vegetable. Antibacterial activity was generally negatively affected by cooking while drying improved the activity. Cooking and drying exerted positive effects on the vegetable's phenolic content and hence its importance in preventing and reducing chronic diseases is enhanced.
