“…According to Cheek, [27], saponins are involved in the treatment of hypercholesterolemia. Kubmarawa et al [28] reported the importance of alkaloids, saponins and tannins in various antibiotics used in treating common pathogenic strains. The leaves of Pterocarpus mildbraedii were also found to contain mineral elements such as calcium, potassium, magnesium, phosphorus, sodium, iron, zinc etc and these elements are very important in human and nutrition.…”

Background: Pterocarpus mildbraedii is used in some Nigerian tribes in the treatment of headaches, pains, fever, convulsions, and respiratory disorders. This study was carried out to ascertain the phytochemicals, minerals and in vitro antioxidant activities of Pterocarpus mildbraedii leaves. Methods: Qualitative phytochemical screening was carried out using standard procedures while Mineral analysis was carried out using Atomic Absorption Spectrophotometer (AAS). Also, antioxidant activities of Pterocarpus mildbraedii leaves were evaluated using reducing power ability and 2,2-Diphenyl-1-picrylhydrazyl (DPPH) radical scavenging assays. Results: Result on phytochemicals reveals the presence of flavonoids, saponins, alkaloids, tannins. Mineral analysis showed calcium (1283mg/kg) to be higher in concentration and manganese (4mg/kg) least in concentration (4mg/kg). Other analysed minerals include sodium (603mg/kg), potassium (1048mg/kg), magnesium (778mg/kg), zinc (25mg/kg), iron (146mg/kg), phosphates (1002mg/kg), etc. In vitro antioxidant activity results show that Pterocarpus mildbraedii possess potent but dose-dependent reducing power ability and free radical scavenging activity against 2,2-diphenyl-1-picrylhydrazyl (DPPH) radicals. Conclusion:The presence of phytochemicals such as flavonoids, saponins, alkaloids and tannins in Pterocarpus mildbraedii provides some biochemical basis for the ethno pharmacological uses of the plant. Also the information provided in this research study may help to spread the ethno botanical uses of Pterocarpus mildbraedii leaves to other parts of the World. The findings clearly demonstrate that Pterocarpus mildbraedii leaves have promising antioxidant property and needs further evaluation to exploit its therapeutic potential.

Phytochemical Screening and Anti-microbial Activity Studies on <i>Leea macrophylla</i> Seed Extracts

et al. 2013

Seed extracts of medicinal plants Leea macrophylla were investigated for phytochemical as well as antibacterial screening. Phytochemical studies of the plant extracts revealed the presence of phenolic, saponin, glycosides, carbohydrate and protein types of compounds. The antibacterial effects of the plant extracts were also tested against several human multidrug resistant pathogens, including one gram positive and three gram negative bacterial species and one fungal species using the disc-diffusion assay. All the plant extracts showed potent anti-microbial effects against gram positive micro-organism (inhibition zone 7-19 mm) whereas none of the extracts produced any potent anti-microbial effects against gram negative bacteria. Furthermore, it has been shown that the extracts exhibit antifungal activities against candida albicans except the extract n-hexane.

“…[18][19][20][21] Promising results were recently obtained from phase 45 Beside these antiplasmodial activities, extracts from N. latifolia were investigated for other anti-protozoal activities, such as toward Leishmania, but showed far less potent activities. [50][51][52][53][54][55][56][57][58][59][60][61][62][63][64][65] The analysis of these data is arduous, due to a lot of discordant antimicrobial activities shown for the same kind of extracts on the same pathogen species. N. latifolia is traditionally used to treat infections and, as a chewing stick, to prevent oral sepsis and dental caries.…”

“…[46][47][48] 3.1.2 Antimicrobial activity. Considering the three most studied bacteria (Staphylococcus aureus, Escherichia coli and Pseudomonas aeruginosa) and an opportunistic fungus (Candida albicans), the key points that can be extracted from the abundant antimicrobial bibliography of N. latifolia are (1) alcoholic extracts were found to be active toward S. aureus and E. coli no matter which plant parts were used (except Kubmarawa et al 56 for S. aureus and Abiodun et al 52 and El-Mahmood et al 57 for E. coli) while ethanolic extracts gave discordant results for P. aeruginosa, and (2) all evaluated types of extract (alkane, ethyl acetate, methanol) from N. latifolia leaves led to an inhibition of the growth of C. albicans. 49 Based on these medicinal indications, many studies have evaluated the antimicrobial potential of extracts of this plant, as summarized in Table 2.…”

Nauclea latifolia: biological activity and alkaloid phytochemistry of a West African tree

et al. 2016

View full text Add to dashboard Cite

Covering up to 2016Nauclea latifolia (syn. Sarcocephalus latifolius, Rubiaceae), commonly called the African pincushion tree, is a plant widely used in folk medicine in different regions of Africa for treating a variety of illnesses, including malaria, epilepsy and pain. N. latifolia has not only drawn the interest of traditional healers but also of phytochemists, who have identified a range of bioactive indole alkaloids in its tissue. More recently, following up on the traditional use of extracts in pain management, a bio-guided purification from the roots of the tree led to the identification of the active ingredient as tramadol, available as a synthetic analgesic since the 1970s. The discovery of this compound as a natural phytochemical was highlighted worldwide. This review focuses on the correlation between extracted compounds and pharmacological activities, paying special attention to infectious diseases and neurologically-related disorders. A critical analysis of the data reported so far on the natural origin of tramadol and its proposed biosynthesis is also presented.
