“…In their study on Phytochemical analysis of different extract of Azadirachta indica Leaves, Virshette et al (2020) detected alkaloids, tannins, phytosterols, and saponins in all extracts of A. indica. This finding is also matching with the research of Madaki et al (2016), who discovered alkaloid and other components in their study of Phytochemical and proximate analyses of methanol leaf extract of Neem Azadirachta indica. Alkaloids are primarily found in plant species, where they often serve as secondary metabolites.…”

The phytochemical screening of (Azadirachta indica) Neem leaf extract was conducted to identify and quantify the presence of bioactive compounds. The study conducted various tests to assess the phytochemical components. About 1kg of matured fresh leaves of (Azadirachta indica) neem was collected from five (5) different location in Bauchi metropolis, these locations are; Kobi Street, Gida Dubu, Yelwan Tudu, Wuntin dada and Federal Low-cost areas in Bauchi metropolis, Bauchi State, Nigeria. The leaves of the plant, which were ground into a fine powder using a mortar and pestle. An ethylacetate solvent was used to derive the A. indica leaf extract. The results of the research shows that the presence of alkaloids, saponins, phenols, and cardiac glycosides in the neem leaf extract is significant, and flavonoids, terpenoids, and steroids were not detected in the neem leaf extract. The presence of alkaloids, saponins, phenols, and cardiac glycosides suggests that neem leaves may hold promise in traditional and contemporary medicinal practices. Alkaloids, known for their pharmacological significance, may contribute to the plant's therapeutic properties. Saponins, with their frothing and foaming characteristics, have been associated with immunomodulatory effects and their potential in agrochemical applications. Phenolic compounds, as evidenced by the positive response to the Ferric chloride test, indicate the antioxidant potential of neem leaves, which can combat oxidative stress. Conversely, the absence of flavonoids, terpenoids, and steroids suggests that these specific phytochemical classes may be limited in neem leaves. These findings open avenues for further research and utilization of neem as a valuable natural resource.

“…46 The total ash content, which represents physiological and nonphysiological ash, is a diagnostic purity index or degree of inorganic matter. 47 The ash content was highest in the R. humilis leaf (17.87 g/100 g) sample. The ash content in the stem, root, and seeds of R. humilis was 14.80 g/100 g, 4.75 g/ 100 g, and 1.87 g/100 g, respectively.…”

Rivina humilis L. (Petiveriaceae), commonly known as the pigeon berry, accumulates betalains in berries. The present study was focused on identifying the phytoconstituents, mineral content, fatty acid composition, phenolics, flavonoids, antinutritional factors, and antioxidant activities of different plant parts (leaf, stem, root, and seeds), which are otherwise not well explored. Phytoconstituent analysis revealed seeds as a potential source of carbohydrates (50.15 g/100 g), proteins (10.96 g/100 g), and fats (11.25 g/100 g). Roots showed the highest fat (17.66 g/100 g) and dietary fiber (81.49 g/100 g). Leaves and roots contain more iron (29.59 and 29.39 mg/100 g), whereas seed has high zinc content (12.09 mg/100 g). Leaf oil showed 47.83 g/100 g of omega-3-fatty acid, confirmed by GC-MS analysis. Seed oil showed 22.23 g/100, 44.48 g/100, and 24.04 g/100 g of palmitic, oleic, and linoleic acids, respectively. The leaf extract has the highest TPC (597.55 mg/ 100 g), followed by the seed (421.68 mg/100 g). The leaf's 80% ethanolic extract had high TFC (2442.19 mg/100 g), followed by 70% methanolic extract (1566.25 mg/100 g). The antinutritional profile indicated significant phytic acid and oxalates in the leaf (9.3 g/100 and 2.07 g/100 g) and stem (6.9 and 1.58 g/100 g) and low tannin content (<0.5 g/100 g). The leaf's 80% ethanolic extract exhibited double the TAA than 70% methanolic extract (1.52 g/100 g). The leaf with an 80% ethanolic extract had the lowest DPPH and ABTS radical scavenging EC 50 (2.22 and 0.37 mg/mL). The leaf with an 80% ethanolic extract (479.73 mg/100 g) and seed (391.14 mg/100 g) had the highest FRAP activity. Our study proves that different parts of R. humilis had a good content of phytoconstituents, bioactives, and antioxidant activities. Hence, R. humilis leaves and seeds are a novel source of omega fatty acids and minerals reported for the first time and have potential applications in the food and pharmaceutical industries.

“…Selain itu tanin menghilangkan substrat (protein) yang berikatan dengan lipid dan protein (Pappa et al 2019), sehingga penyimpanan semakin lama menyebabkan kadar protein pada ikan patin semakin rendah. Sementara itu, kadar protein meningkat dengan semakin tingginya konsentrasi ekstrak daun mimba hal ini berkaitan dengan kadar protein dalam daun mimba yang meningkat dengan semakin tinggi kosentrasi ekstrak daun (Madaki et al 2016).…”

Catfish (Pangasianodon hypophthalmus) like other animal products decay quickly. The way to extend the shelf life is with edible coating which is added with neem leaf (Azadirachta indica A Juss.) extract as an antibacterial agent. The research objective was to find out the effect of neem leaf extract as an antibacterial on coated fresh catfish during cold stored. The study used a completely randomized design with two independent variables and two replications. The first independent variable was the concentration of neem leaf extract with levels of 2.5; 5; 7.5% v/v. The second was storage time of 0, 2, and 3 days. The results of the ANOVA test showed that the concentration of neem leaf extract and the duration of storage time affected the quality of catfish meat which was coated and stored in the refrigerator except for moisture content parameter. The best formulation was obtained in edible coating with a concentration of 7.5% neem leaf extract and storage time of 3 days. The quality of the coated fish had a moisture content of 72.05% db, ash 2.66% db, protein 9.33% db, fat 1.91% db, carbohydrates 14.06% db and TPC 5.57 log CFU/g. The results of the organoleptic test on fish fried without seasoning showed the color, texture, aroma and taste were pale white (ln 3,7), soft (ln 3,6), fishy (ln 3,6), and not bitter (ln 3,7) respectively, which the panelists liked.
