Mango Leaves

Mangifera indica L. belongs to the family of Anacardiaceae and is an important fruit from South and Southeast Asia. India, China, Thailand, Indonesia, Pakistan, Mexico, Brazil, Bangladesh, Nigeria, and the Philippines are among the top mango producer countries. Leaves of the mango plant have been studied for their health benefits, which are attributed to a plethora of phytochemicals such as mangiferin, followed by phenolic acids, benzophenones, and other antioxidants such as flavonoids, ascorbic acid, carotenoids, and tocopherols. The extracts from mango leaves (MLs) have been studied for their biological activities, including anti-cancer, anti-diabetic, anti-oxidant, anti-microbial, anti-obesity, lipid-lowering, hepato-protection, and anti-diarrheal. In the present review, we have elaborated on the nutritional and phytochemical profile of the MLs. Further, various bioactivities of the ML extracts are also critically discussed. Considering the phytochemical profile and beneficial effects of the MLs, they can be used as a potential ingredient for the development of functional foods and pharmaceutical drugs. However, more detailed clinical trials still needed to be conducted for establishing the actual efficacy of the ML extracts.

Berries, from the genusRubus, are among the vital components in a healthy diet. In this study, 80% methanol extracts from the three wildRubusspecies (Rubus moluccanusL.,Rubus fraxinifoliusPoir., andRubus alpestrisBlume) were evaluated for their phytochemical contents (total phenolics, flavonoid, anthocyanin, and carotenoid content), antioxidant (DPPH, FRAP, and ABTS assays), antiacetylcholinesterase, and antibacterial activities. GC-MS was used for quantification of naturally occurring phytochemicals. The results showed thatR. alpestriscontained the highest total phenolic [24.25±0.1 mg gallic acid equivalent (GAE)/g] and carotenoid content [21.86±0.63 mgβ-carotene equivalents (BC)/g], as well as the highest DPPH scavenging and FRAP activities. The highest total flavonoid [18.17±0.20 mg catechin equivalents (CE)/g] and anthocyanin content [36.96±0.39 mg cyanidin-3-glucoside equivalents (c-3-gE)/g] have been shown byR. moluccanus. For antibacterial assays,R. moluccanusandR. alpestrisextracts showed mild inhibition towardsBacillus subtilis,Staphylococcus aureus,Escherichia coli, andSalmonella enteritidis. Anticholinesterase activity for all extracts was in the range of 23–26%. The GC-MS analysis revealed the presence of at least 12, 21, and 7 different organic compounds in 80% methanol extracts ofR. alpestris,R. moluccanus, andR. fraxinifolius, respectively, which might contribute to the bioactivity.

AbstractSeaweeds are able to produce a great variety of secondary metabolites that are characterized by a broad spectrum of biological activities. Two seaweeds species, namelyHypnea musciformisandEnteromorpha intestinalis werestudied to evaluate the phytochemical constituency and antimicrobial activities. First of all, crude extracts of both sea weeds were prepared by two different extraction methods (soaking and water bath) using different solvents. Phytochemicals profiling results revealed the presence of bioactive compounds (flavonoids, alkaloids, tannin, saponin and phenols) in both seaweed extracts. Quantification results for ethanolic extracts ofH. musciformis and E. intestinalisestimated 51 mg and 43 mg tannins in per gram of dried samples and flavonoids contents were found 67 mg and 57 mg/g mg QE/g respectively. Total phenolic contents were determined in terms of gallic acid equivalent (GAE).H. musciformisexhibited higher amount of phenolics (59 ± 0.0002 mg GAE/g) thanE. intestinalisextracts (41 ± 0.0002 mg GAE/g). In antimicrobial activity test, ethanol extractsof H. musciformisandE. intestinaliswere found 10 mm of inhibition diameter against all of the bacterial strains. Besides, methanol extracts ofE. intestinaliswere more susceptible toStaphylococcus aureus and Pseudomonaswhich was close to the inhibition diameter (>15 mm) of the mainstream antibiotic; Gentamicin. Moreover,Klebsiella sp. was found more susceptible to ethanol and methanol extracts of Hypnea musciformisas it showed inhibition zone greater than 15 mm. Both Seaweed extracts possessed higher amount of phytochemicals and showed promising antimicrobial activities when compared with the standards.
