“…The limiting amino acids have the lower amino acid indexes. For leaves, they are the sulfur amino acids [28]. In our study, it was the lysine for the reniform leaves from Antananarivo and the round leaves from Tsiroanomandidy, methionine and cystein for the reniform leaves from Moramanga and the round leaves from Analavory.…”

Centella asiatica is a herbal plant generally used for its curative properties. Two foliar morphotypes were recently identified in Madagascar: a reniform tetraploid (2n = 4x = 36) in the Center and the East of the island and a round diploid (2n = 2x = 18) in the West. The objective of this study was to evaluate the nutritional properties of these two morphotypes and to compare them with other green leafy vegetables. Reniform leaves were collected in Antananarivo and Moramanga and round leaves were collected in Tsiroanomandidy and Analavory. Macronutrient content was determined by standard methods, mineral contents were analysed by inductively coupled plasma atomic emission spectroscopy. Ascorbic acid and carotenoids were quantified by HPLC. Food composition showed significant differences between the morphotypes. Reniform leaves have higher protein content (19-22 % dry weight (DW)) than round leaves (17-21 % DW). Lipid content are from 2.5 to 6.0 % DW. Reniform leaves have higher iron content than round leaves. Iron content of C. asiatica's leaves range from 3.8 to 12.5 mg/100 g fresh weight (FW). Reniform leaves from Moramanga have the highest protein, lipid and iron content. Round leaves from Analavory have the highest calcium and magnesium content, which can cover 41 % and 17 % of the Recommended Dietary Allowances (RDA), respectively. Leaves of C. asiatica have low vitamin C content (1.3 to 7.7 mg/100 g FW). Consumption of 100 g of C. asiatica leaves could cover 10 to 21 % of vitamin A daily requirements of women for reniform leaves and 21 to 37 % of vitamin A requirement of women for round leaves. Round leaves from Analavory have the highest β-carotene content. It is hoped that from these findings, the people of Madagascar will be encouraged to include C. asiatica in their diets for its nutritional benefits.

“…The differences in this result are probably due to the sensitivity of the analytical instruments. Previous research showed that metabolites such as ascorbic acid, cycloalliin, 5hydroxymethyfurfural (5-HMF) have a good antioxidant, anti-ageing and anti-inflammatory activities (Superko and Krauss, 2000;Akhtar et al, 2012;Ahmed and Othman, 2013). The presence of these metabolites makes PRM a suitable candidate for bioactives mixture in preventing and treating metabolic diseases.…”

This study was aimed to provide the reference frame for the safe dose design of polyphenol-rich herbal mixture, which consist of lemon, apple cider, garlic, ginger and honey (PRM) for the future efficacy study. Prior to this, the nutritional composition was first conducted and the identification of metabolites that present in PRM was determined using proton nuclear magnetic resonance (1H-NMR) spectroscopy. The acute toxicity of the PRM was then evaluated in zebrafish embryo and Wistar rats following The Organisation for Economic Co-operation and Development (OECD) guidelines. The PRM nutritional composition and sugar profile showed it was high in carbohydrate, ash and protein and the main sugar is fructose. It also contains metabolites such as fructosefuranose, lactic acid, ascorbic acid, acetic acid, cycloalliin, pyruvate, 5- hydroxymethylfurane, α- and β-glucose. From the zebrafish embryo acute toxicity result, the lethal concentration, LC50 of PRM was at 487.50 μg/mL. Meanwhile, in Wistar rats’ model, no lethality was observed in the group treated with PRM at the end of the study (14 days). No changes were also observed from the behavioural and appetite as well as the biochemical parameters (AST, ALT, total cholesterol, triglyceride, LDL, HDL, total protein and creatinine) of the treated group. Therefore, the safe dose for PRM can be up to 2000 mg/kg b.w. in Wistar rats and below 487.50 μg/mL in zebrafish embryo model.

“…Due to natural in origin they are absolutely safe without any side effects. According to Akhtar et al (2012) alternative leafy vegetables are now proved to improve immunity and recognize as an ally in the fight against deficiency of macro and micronutrients. In this calamity of Covid 19,there is a God gifted plant named as "Moringa"which can be an efficient safeguard for all of us against this novel infection by curbing malnutrition and enhancing our immunity.…”

Malnutrition plays a leading role for major health problems globally. It is more prevalent in developing countries. Most people in developing country have a restricted diet on daily basis, resulting in micronutrient deficiencies and, as result malnutrition. Malnutrition is the main threat for the loss of wellbeing among all age group of people in India. It also leads to weak immunity. COVID-19 pandemic has infuriated this situationin the country. In this critical circumstances of Covid pandemic, there is a basic need to fulfill all the nutritional requirement of the body and give it a proficient protection to keep it battling respectably against all lethal infections including Covid-19. Moringa is a versatile God gifted plant, which is packed with a number of essential nutrients required for a healthy body, so can be a natural and competent shield for all of us by controlling feeble wellbeing and may prove a boon to our safety
