“…The aqueous extract of D. erecta fresh leaves was collected from the residential quarters within the University of Nigeria, Nsukka, indicated small quantities (+) of alkaloids, flavonoids, tannins, anthraquinone, and glycosides in the extract, while saponins were moderately present (++), steroids were conspicuously absent [26]. The 70% aqueous ethanol of D. erecta L. leaves was collected from Nigeria indicated the presence of secondary metabolites such as steroidal glycoside, saponins, flavonoids, polyphenols/tannins, alkaloids, and terpenes [27]. The difference in phytochemicals results was presumably due to several factors, such as growing area, environmental stress such as heavy metals or ultraviolet exposure, age of plants, genetic factors, and physical factors such as climate, humidity, temperature, and weather [28].…”

Objective: Phytochemicals are naturally present in every part of plants range from leaves, stem bark, and fruits to roots. The use of plant-based medicine is popular among individuals and communities in developing countries. This study evaluated that the phytochemical profile of Duranta repens fruits was collected from Jombang, East Java, Indonesia. Methods: Air-dried D. repens fruits were macerated by n-hexane and methanol, a separate flask. n-Hexane extract, then underwent saponification to remove fat. Then, the unsaponifiable of n-hexane and methanol extract was tested through phytochemical screening, respectively. Results: The methanol extract showed the presence of alkaloids, flavonoids, tannins, and steroids, but the unsaponifiable fraction only contained steroids. The unsaponifiable fraction was found to be a mixture of hydrocarbons ranging from C13-C20, fatty acids (palmitic and linoleic acid), squalene, and Vitamin E. Conclusion: The phytochemical screening of the plant plays an important role for pharmaceutical studies especially discovering new potential drugs for the treatment of various diseases.

“…The proximate composition of a food material is important in evaluating its nutritional and health value and in determining the safety, toxicology and stability of the food to chemical, physical and microbiological changes [14]. The proximate composition of the B. patula leaves is shown in Table 1.…”

Aim: To determine the nutritional and anti-nutritional compositions of Brillantaisia patula leaves using standard analytical methods. Place and Duration of Study: The proximate, mineral and anti-nutritional compositions were determined in the chemistry laboratory of Ekiti State University, Ado – Ekiti while the amino acid was determined at the Analytical Laboratory of Multi-Environmental Management Consultant, Lagos, Nigeria. Methodology: The proximate composition was carried out using the methods of Association of Official Chemists (AOAC) while mineral and anti-nutritional compositions were determined using standard analytical methods. Amino acid analysis was carried out through ion exchange chromatography (IEC) using the Technicon Sequential Multisample (TSM) Amino Acid Analyser. Results: The proximate composition ranged from 3.18% (crude fat) to 38.6% (carbohydrate). The major mineral constituents of the sample were: P (1061 mg/100g), K (874 mg/100g), Ca (799 mg/100g), Na (82.6 mg/100g) and Mg (24.3 mg/100g) while the minor mineral constituents were: Fe (26.9 mg/100g), Zn (7.7 mg/100g) and Mn (6.05 mg/100g). The evaluated anti-nutritional contents were: 6.71 mg/g oxalate, 5.37 % saponin, 1.0 mg/100g tannin and 4.72 mg/kg cyanide. Additional results showed that the leaves contained eighteen amino acids with values ranging from 0.504 g/100g cp (tryptophan) to 14.0 g/100g cp (glutamic acid). The value of the total essential amino acids (TEAA) with histidine was 45.6g/100g cp while the total non-essential amino acid (TNEAA) was evaluated to be 46.5 g/100g cp. Conclusion: Brillantaisia patula leaves could be utilized as a good source of essential amino acids and important mineral elements.

“…The differences in the potassium content of the leaves as compared to previous studies could be attributed to the methods of processing, geographical area of harvest and time of harvest. The presence of potassium may make them excellent sources of nutrient for boosting the immune system [45]. It has also revealed that diet rich in potassium may help to reduce blood pressure, water retention, protect against stroke and prevent osteoporosis [46].…”

This study described the chemical composition, antioxidant and antibacterial activities of the ethanol and aqueous extracts of fresh and dried leaves of Phyllantus amarus (PA) (Stone breaker), Cymbopogon citratus (CC) (Lemon grass) and combination of stone breaker and lemon grass (PA/CC and DL/DP) using standard methods. The proximate and mineral results showed that both fresh and dried samples of Phyllantus amarus and Cymbopogon citratus were rich in crude fibre (18.53%, 14.65%), ash (16.27%, 2.29%), potassium (95.56 mg/100g, 54.04 mg/100g), calcium (58.57 mg/100g, 7.05 mg/100g), and sodium (15.23 mg/100g, 9.84 mg/100g) respectively. The ability of the extracts to scavenge 2, 2 diphenyl -2- picryl-hydrazyl (DPPH) radical showed that the fresh PA had the highest scavenging activity of 91.12 mg/g, followed (PA/CC) 90.93 mg/g and dried PA (85.61mg/g). The phytochemical composition of the extracts also revealed that they contain high content of cardiac glycoside (11.62 mg/g - 64.81 mg/g), terpenoid (14.56 mg/g - 69.66 mg/g), phenol (14.73 mg/g - 53.93 mg/g), saponin (22.61 mg/g - 30.47mg/g). Dried lemon and dried Phyllantus amarus (DL/DP) was found to be rich in Vitamin A (22.22 mg/g), while the lowest value of Vitamin E (0.36 mg/g) was obtained from fresh lemon grass (0.36mg/g). Antibacterial assay carried out on the two leaves extracts showed that they produced mild antibacterial activity against some foodborne pathogen (Bacillus cereus, Shigella dysenteriae, Escherichia coli, Salmonella spp, Staphylococcus aureus, Pseudomonas spp). with zones of inhibition of 4.3 mm -9.1mm. Further studies should be carried out to investigate the employment of the leaves in production of functional food
