“…The present results contrast those of Asante et al (2014), who established that high application of nitrogen did not influence the accumulation of nutrients (N, P, K, Ca and Mg) in M. oleifera leaves. Indeed, the mineral content in leaves of M. oleifera was reported to be linked to the environmental conditions (soil and climate), production areas, leaf maturity (dark and mature leaves being generally more rich in nutrients than young and clear leaves), cropping methods (irrigation, fertilizers), harvest season and the genetic makeup of trees (De Saint Sauveur and Broin 2010).…”

Purpose The nursery is the production of vigorous seedlings for field transplantation. Fertilization improves the quality of Moringa oleifera in the greenhouse. Thus, the effect of composts amendments on the survival rate and mineral composition of M. oleifera was studied. Methods A randomized complete block (RCB) design comprising fourteen treatments and twelve repetitions (pots referring to as repetitions), was led out in greenhouse. Varying compost receipts (0.1 kg, 0.2 kg, and 0.3 kg) were used and an increasing amount of a chemical fertilizer (NPK: 20:10:10) was added in some treatment at 25 days after sowing. Parameters such as germination rate, survival rate, biomass, and mineral composition of M. oleifera plants were assessed. Results The germination rate was maximal (100%) in the combined treatment PM 1 (0.8 kg of soil + 0.1 kg). A considerable reduction of germination rate and high plantlet mortality were observed in treatments that received chemical fertilizer, although the mineral components' uptake in young M. oleifera plants was considerably improved. The highest dry root biomass was obtained from the treatments MF 1 (0.8 kg of soil + 0.032 kg each of cow dung, goat, chicken manures + 0.003 kg NPK) and CM 1 (0.8 kg of soil + 0.1 kg of cow dung compost), with, respectively, 0.62 g and 0.59 g per plant. Conclusions All composts types used in this study have appeared as appropriate amendments to improve the M. oleifera production in nursery, through an increase of the vigour and mineral composition of this valuable plant.

“…Raw roselle seeds from Adamaoua region recorded higher mean dry matter content than that of West region. These results are similar to those of William et al (2013) obtained with Moringa oleifera plant cultivated in two agro ecological area in Ghana where Moringa leaves from Guinea savanna zone recorded the higher dry matter content than that of the semi-deciduous forest zone. The crude protein content was the same in the two agro ecological zones.…”

Abstract:The chemical composition and protein quality of raw, boiled, toasted and soak-toasted roselle seeds harvested in the North (area I) and West (area II) regions of Cameroon were investigated in this study. To conduct the growth and nitrogen balance study, sixty albinos wistar rats of 21 to 25 days separated into ten groups of six rats/group were used and fed for fourteen days with 10% (w/w) isoproteinous experimental diets. These groups were Protein free diet (D0), egg white-standard reference protein diet (D1) and raw (D2I, D2II), boiled (D3I, D3II), toasted (D4I, D4II) and soak-toasted (D5II, D6II) roselle seed diets. Transaminases, serum creatinine, haematocrit, lipid parameters were also assessed in the rats. Results showed that crude protein, lipid, fiber and ash content of seed samples ranged respectively from 22 to 26, 18 to 22, 18 to 23 and 4.3 to 6.4%. The contents of Ca, Mg, K, Na, P, Fe and Zn were ranged from 1054 to 1920, 1670 to 2083, 26.45 to 272.7, 14 to 22, 10.58 to 90.78, 137.3 to 169.22 and 10.13 to 70.11 mg/kg respectively. Food intake was higher (P<0.05) for groups D1, D3I and D3II than for others groups. The rats fed with reference diet followed by boiled seed diets had the highest (P<0.05) weight gained, protein efficiency ratio (PER), net protein ratio (NPR), feed efficiency (FE), efficiency of food utilization (EFU) and true digestibility (TD). Aspartate aminotransferase and alanine aminotranferase were highest (p<0.05) in the rats fed raw roselle seeds. Compared to reference diet, the total cholesterol (TC), triglycerides (TG) and LDL-C of rats fed with diet D5II decreased while the HDL-C did not show any significant changes in these rats (p˃0.05). These findings show that roselle seeds cultivated in Cameroon have important amount of macronutrients and minerals. Proteins of roselle seeds are of good quality especially from the boiled seeds and are not influenced by the agro ecological region. Consumption of roselle seeds might be beneficial for cardio protective effect and no toxicity was observed as far as transaminases are concerned except that for the raw seeds which showed significant hepatotoxicity.

“…These contents were also in accordance with those reported by Asante, Nasare, Tom-dery, and Ochire-boadu (2014), studing M. oleifera leaves from the semi-deciduous forest zone of Ghana. However, Guinea savanna M. oleifera leaves revealed slightly higher values (25.34 and 26.98 g/100 g dw) (Asante et al, 2014). Nevertheless, Amabye (2016) presented a lower content (10.74 to 11.48 g/100 g dry leaf powder) in the commercial sample of M. oleifera from Mekelle.…”

Edible Ammodaucus leucotrichus Cross. & Dur. and Moringa oleifera Lamarck are largely used in the Algerian Sahara. In this context, soluble sugars, fatty acids, organic acids, and tocopherols were characterized. Decoctions and hydroethanolic extracts were studied regarding their phenolic compounds by HPLC-DAD-ESI/MSn, and invitro cytotoxic, anti-inflammatory, and antibacterial activities were evaluated. Results indicate high contents of carbohydrates (glucose and sucrose) and significant levels of protein and mineral were recorded for both plants. Malic acid was the major organic acid alongside with α-tocopherol, while PUFA was predominant in M. oleifera and MUFA in A. leucotrichus. Flavonoid derivatives were the most abundant group, being luteolin-O-(malonylglucoside) the main compound in A. leucotrichus and quercetin-3-O-(6″-malonyl-glucoside) and 3-O-caffeoylquininc acid the major molecules in M. oleifera. Extracts exhibited significant cytotoxicity on Hela and MCF-7 cell lines. The anti-inflammatory activity was also higher in the hydroethanolic extracts, which also revealed the highest antibacterial effects, especially for Gram-positive bacteria. leucotrichus Coss. & Dur. (Apiaceae) is an endemic plant in North Africa and is widely used in traditional medicine, especially in the southern Algerian Sahara and Tassili regions (Louail et al., 2016). Leaves and seeds of this plant are consumed in the form of infusions and/or decoctions for several therapeutic cases, such as liver and digestive system ailments, gastroenteritis, diabetes, as also for blood pressure and chest pain (Halla, Boucherit, Boucherit-otmani, Zohra, & Rahmani, 2018; Louail et al., 2016). The fruits are often used as a spice during culinary preparation, and leaves are used as a flavoring herbal in teas (Halla et al., 2018; Louail et al., 2016). Nevertheless, most phytochemical and biological studies on A. leucotrichus are related to the volatile compounds from the essential oils (Gherraf et al., 2017; Halla et al., 2018), and few scientific studies have been conducted towards the phenolic compounds and their functional properties. According to a recent study conducted by Halla, Heleno, Costa, Fernandes, Calhelha, Boucherit, Rodrigues, Ferreira, and Barreiro (2018) using colorimetric reactions, flavonoids, condensed and hydrolysable tannins, coumarins, alkaloids, and terpenoids were found in the Algerian A. leucotrichus aqueous extract obtained by decoction and in the hydromethanolic extract. El Haci, Mazari, Gherib, and Atik Bekkara (2018) reported moderate
