Phytochemical Compounds

The phytochemical compounds of Bridelia ferruginea plant parts was carried out using qualitative method to determine the bioactive compounds present in the plant leave, stem bark and root extracts. The samples was weighed, of which 100 g each of the powder were extracted in solvents (ethanol) 1000 ml macerated and stand for 72 hours. The solvents contained in the maceration bottle was decanted and filtered using a filter paper, the filtration was aided using a suction pump. The filtrate was concentrated using a rotary evaporator and then transferred into thermostatic water cabinet (Temperature was set at 45oC), allowed to dry completely. The plant parts extracts were separately kept in a screw capped bottle for further research. The bioactive compound in the plant parts were detected. The result revealed that Carbohydrates, Saponins, Flavonoids, Tannins, Cardiac Glycosides, fats and oils were present. Alkaloid present in Dragendoff’s test in all plant parts extract but absent in Mayer’s test in only leaf extract. Terpenoids/Steroids present in Liebermann-Burchard’s test in all plant parts extract but absent in Salkowski’s test in only leaf extract. Anthraquinones were absent in all plant parts extracts using Bontrager’s test. Therefore, the presence of these phyto-pharmacological compounds is an indicative that the plant is medicinal and it can be used for the treatment of bacterial and other microbial infections. Further study can be done to separate the individual metabolites to test their antimicrobial activity against some pathogenic bacteria like bacterial meningitis, tuberculosis and syphilis to determine their potency.

The ethanol extracts of root, bark and leaf of Bridelia ferruginea was investigated for antibacterial activity against clinical isolate of Staphylococcus aureus and Escherichia coli. The extracts had significant antibacterial activity in vitro at concentration of 25 mg/ml, 50 mg/ml, 100 mg/ml and 200 mg/ml and in vivo at dose of 50 mg/kg and 100 mg/kg. The root extract in vitro had the highest zone of inhibition, followed by the bark extract for both Staphylococcus aureus and Escherichia coli. The concentration of 200 mg/ml had the highest zone of inhibition in vitro. The minimum inhibitory concentration (MIC) showed a decreasing inhibitory effect of the plant extracts for both Staphylococcus aureus and Escherichia coli as the concentration decreases with root having 3.125 mg/ml, bark having 6.25 mg/ml and leaf having 25 mg/ml for Staphylococcus aureus and Escherichia coli. Likewise, the minimum bactericidal concentration (MBC) showed decreasing bactericide effects with decrease concentration with root having 12.5 mg/ml, bark having 12.5 mg/ml and leaf having 25 mg/ml for Escherichia coli while root had 6.25mg/ml, bark had 12.5mg/ml and leaf had 25mg/ml for Staphylococcus aureus. The in vivo investigation showed that the root and bark extract exhibited antibacterial activity on both Staphylococcus aureus and Escherichia coli at doses of 100mg/kg and 50mg/kg; the root extract had higher activity than the bark and root/bark combined. The dose of 100 mg/kg had the highest colonies reduction for Staphylococcus aureus and Escherichia coli in vivo. Preliminary phytochemical screening of root, bark and leaves of Bridelia ferruginea revealed the presence of tannins, flavonoids, carbohydrates, cardiac glycoside (root, bark and leaves), saponins (root and bark). The presence of tannins, saponins, flavonoid, cardiac glycoside and carbohydrate in the bark and root extracts of the plant indicates that the bark and root extracts were pharmacological importance

Millettia aboensis (Hook.f.) Baker belongs to the Leguminosae family, known locally as nduezi in Igbo, erurumesi in Edo, and Òdúdū in Efik. The plant parts have proven to be active against some diseases. The plant was studied for its antimicrobial activity and the phytochemicals present. The plant materials were macerated and fractionated using different extraction methods. The compounds present in the fractions of the stem were detected with the aid of HPLC-DAD. The efficacy of the crude methanol and fractions from the root part was evaluated against Streptococcus mutans. The results showed that the aqueous fraction extract had the highest percentage yield (51.11%), followed by the ethyl acetate (24.10%), butanol (6.63%), and hexane (5.56%), while the methanol extract had a yield of 2.48%. Nine phytochemical compounds were detected from the fractions of the root extract: bis-oxazolidinone derivative – 1, circumdatin F – 2, enniatin B – 3, septicine – 4, orobol 8-C-glucoside – 5, rocaglamide – 6, genistein 6-C-glucoside – 7, 3-phenyl chromen-4-one – 8, and corynesidone D – 9. The methanol extract/fractions of M. aboensis showed no antimicrobial activities on clinical isolates at different concentrations (6.25-50 mg/ml). Based on the poor activity against Strep. mutans, but with promising phytoconstituents present, the extract/fractions need further investigation as regards its utilization against other pathogens.

The antibacterial and antifungal activities of various extracts from Urtica urens were evaluated against selected microorganisms using agar hole-plate diffusion method. A total of ten extracts namely U. urens hexane leaf extract (HLE), chloroform leaf extract (CLE), ethyl acetate leaf extract (ELE), methanolic leaf extract (MLE), hexane stem-bark extract (HSB), chloroform stem-bark extract (CSB), ethyl acetate stem-bark extract (ESB), methanolic stem-bark extract (MSB), chloroform root extract (CRT) and methanolic root extract (MRT) were prepared. These extracts were evaluated against two Gram-positive bacteria viz. Listeria monocytogenes and Staphylococcus aureus, four Gram-negative bacteria viz. Serratia marcescens, Pseudomonas aeruginosa, Escherichia coli (wild strain) and Escherichia coli (O157:H7) and two fungal isolates viz. Candida albicans and Penicillium digitatum. The inhibition zones of these extracts were found to be in the range of 9.0±0.0 to 40.5±0.7 mm against bacterial isolates and 16.0±4.2 to 17.5±4.9 mm against C. albicans. However, all these extracts exhibited no visible zone of inhibition against P. digitatum. Additionally, the minimum inhibitory concentrations (MICs) of these extracts were also determined and were found to be in the range of <31.25 to >1000 µg/mL against both bacterial and fungal isolates. From this study, we concluded that ELS, MLE, CRT and MRT showed promising antimicrobial activities.

Rauwolfia vomitoria is a plant used for the treatment of insanity. The possible adverse effects of crude ethanolic root bark and leaf extract of the plant on Nissl substances of albino Wistar rat fetuses were studied using 25 mature female Wistar rats. The animals were divided equally into 5 groups, labeled A, B, C, D, and E. Group A was the control, while groups B, C, D, and E were the experimental. The female rats were mated with the males overnight, and the sperm positive day was designated as day zero of pregnancy. Oral doses of 150 mg/kg and 250 mg/kg body weight of the root bark extract were administered to groups B and C animals, respectively, while groups D and E animals received 150 mg/kg and 250 mg/kg body weight of the leaf extract, respectively, from day 7 to 11 of gestation. On day 20 of gestation, the rats were sacrificed, the fetuses brains extracted, and the cerebral cortices excised and routinely processed for Nissl substances using Cresyl fast violet staining method. Results showed reduced staining intensity of Nissl substances in the treated groups, especially those that received the root extract. Thus, the herbs may have adverse effects on protein synthesis within the cerebral cortex.

Phytochemical Components

Most of biochemical reactions in the body generates Reactive Oxygen Species (ROS), which are involved in the pathogenesis of oxidative stress-related disorders like diabetes, nephrotoxicity, cancer, cardiovascular disorders, inflammation and neurological disorders when they attack biochemical molecules like proteins, lipids and nucleic acid. Antioxidants are used to protect the cells or tissues against potential attack by ROS. Most medicinal plants possess a rich source of antioxidants such as flavonoids, phenols, tannins, alkaloids among others. These phytochemicals are currently pursued as an alternative and complimentary drug. In this study, phytochemical components, antioxidant and acute toxicity study of the methanol extract of stem bark and root of F. sycomorus were carried out using standard methods. Findings from this study revealed the presence of some diagnostic microscopical features such as calcium oxalate, starch, gum/mucilage, lignin, Aleurone grain, suberized/Cuticular cell wall and inulin but calcium carbonate was absent in stem bark but present in the powdered root. Quantitative physical constants include moisture contents (6.40% and 7.82%), ash value (7.20% and 9.30 %) in stem bark and root respectively. Carbohydrates, alkaloid, flavonoids, saponins, tannins, glycoside, steroid, triterpenes and phenols were present in all the extracts. They were found to exhibit potent 1,1,-diphenyl 2-picryl hydrazyl (DPPH) free scavenging activity. The DPPH radical scavenging ability of the extracts showed the following trend Ascorbic acid < stem bark extract˃ root extract. The LD50 of the methanolic stem bark and root extracts were found to be greater than 5000 mg /kg and is considered safe for use. Nonetheless, further
