Oyedeji-Amusa MO, Sadgrove NJ, Van Wyk BE. The Ethnobotany and Chemistry of South African Meliaceae: A Review. PLANTS (BASEL, SWITZERLAND) 2021; 10:1796. [PMID: 34579329 PMCID: PMC8466584 DOI: 10.3390/plants10091796] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/13/2021] [Revised: 07/27/2021] [Accepted: 07/29/2021] [Indexed: 11/16/2022]
Abstract
Meliaceae are widely distributed across the world in tropical or subtropical climates and are of considerable ethnobotanical importance as sources of traditional medicine and cosmetics. This comprehensive review summarizes the ethnobotanical uses and chemistry of 12 South African species, belonging to six genera: Ekebergia, Nymania, Entandrophragma, Pseudobersama, Trichilia, and Turraea. Eight of the species have ethnomedicinal records, classified into 17 major disease categories. The ethnomedicinal uses comprise 85 ailments dominated by gastrointestinal complaints, followed by gynaecological and obstetrics related problems. Chemical records were found for 10 species, which describe nine classes of compounds. In nearly all South African Meliaceae, limonoids are the predominant constituents while triterpenes, sterols, and coumarins are also common. The widest range of use-records and medicinal applications are found with the two most chemically diverse species, Ekebergiacapensis and Trichiliaemetica. Of the chemical compounds identified in the various plant organs of the 10 species of South African Meliaceae for which data are available, 42% was found in bark and 17% in seeds. Roots represent 35% and bark 33% of the organs that are used medicinally, and they are typically prepared as decoctions or infusions. Root and bark harvesting are destructive so that it may be important to examine the chemistry of plant parts such as wild-crafted leaves and fruits.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Mali is one of the countries in West Africa where the health system rely the most on traditional medicine. The healers are mainly using medicinal plants for their treatments. The studies performed being the basis for this review is of importance as they will contribute to sustaining the traditional knowledge. They contribute to evaluate and improve locally produced herbal remedies, and the review gives also an overview of the plant preparations that will have the most potential to be evaluated for new Improved Traditional Medicines. AIM OF THE REVIEW The aim of this review is to give an overview of the studies performed related to medicinal plants from Mali in the period 1995-2015. These studies include ethnopharmacology, chemistry and biological studies of the plants that were chosen based on our interviews with the healers in different regions of Mali, and contribute to sustainable knowledge on the medicinal plants. The Department of Traditional Medicine, Bamako, Mali, is responsible for registering the knowledge of the traditional healers on their use of medicinal plants and also identifying compounds in the plants responsible for the bioactivities claimed. The studies reported aimed at getting information from the healers on the use of medicinal plants, and study the biology and chemistry of selected plants for the purpose of verifying the traditional use of the plants. These studies should form the basis for necessary knowledge for the development of registered Improved Traditional Medicines in Mali. MATERIALS AND METHODS The healers were the ethnopharmacological informants. Questions asked initially were related to wound healing. This was because the immune system is involved when wounds are healed, and additionally the immune system is involved in the majority of the illnesses common in Mali. Based on the results of the interviews the plant material for studies was selected. Studies were performed on the plant parts the healers were using when treating their patients. Conventional chromatographic and spectroscopic methods were used for the isolation and structural elucidation of compounds. The compounds to study were selected based on the bioassays performed concomitant with the fractionation. RESULTS Our results show that plants traditionally used as wound healing agents contain polysaccharides basically of pectin nature with immunomodulating activities. These pectins all have different and new structures. Several of the plants also contain compounds with effects related to antioxidant properties. These compounds are mainly of polyphenolic nature. Three of these are new compounds from Nature, while 32 was for the first time described from the plant they were isolated from. This review gives an overview of the most important results obtained during the 20 year long collaboration between Department of Traditional Medicine, Bamako, Mali, and Department of Pharmacognosy, School of Pharmacy, University of Oslo, Norway. CONCLUSION Our studies showed that ethnopharmacological information is important for the determination of screening and chemical methods to be used for studies of plants used in traditional medicine.

Nergard CS, Ho TPT, Diallo D, Ballo N, Paulsen BS, Nordeng H. Attitudes and use of medicinal plants during pregnancy among women at health care centers in three regions of Mali, West-Africa. JOURNAL OF ETHNOBIOLOGY AND ETHNOMEDICINE 2015; 11:73. [PMID: 26453339 PMCID: PMC4600315 DOI: 10.1186/s13002-015-0057-8] [Citation(s) in RCA: 28] [Impact Index Per Article: 3.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/23/2015] [Accepted: 09/18/2015] [Indexed: 05/21/2023]
Abstract
BACKGROUND Although, medicinal plants have been important for women's health historically, the knowledge about such use during pregnancy in developing countries is limited. This is the first quantitative, ethnobotanical study on Malian women's use of and attitudes towards the use of medicinal plants during pregnancy. The aim of the study was to describe Malian women's use of medicinal plants during pregnancy according to indications and to evaluate the potentially safety of such use. The overall aim was to preserve valuable information about medicinal plants for women's reproductive health for the future. METHODS Data was collected through structured interviews of 209 pregnant women or mothers in three health care centers in Mali. The women were interviewed about their uses of medicinal plants during pregnancy and their attitudes to such use. Nine specific medicinal plants commonly used in Mali and treatment of eleven common ailments in pregnancy were specifically queried about. RESULTS In total, 79.9 % had used medicinal plants during pregnancy. Only 17 women (8.5 %) had received a recommendation from a traditional practitioner (TP). The most commonly used medicinal plants were Lippia chevalieri (55.5 %), Combretum micranthum (39.7 %), Parkia biglobosa (12.0 %) and Vepris heterophylla (8.1 %). The most common reasons for use were for well-being (37.7 %), symptoms of malaria (37.1 %) and "increased salt-elimination" (to reduce edema) (19.2 %). For treatment of symptoms of malaria and urinary tract infections during pregnancy, the women's choices of medicinal plants agreed with those previously reported from interviews with TPs. Almost 30 % believed that medicinal plants had no adverse effects for the mother. CONCLUSION This study showed an extensive use and knowledge of medicinal plants during pregnancy in three regions in Mali. However, exclusive use of medicinal plants as treatment of malaria and urinary tract infections during pregnancy may pose a health risk for the mother and her unborn child. A wider collaboration with TPs, with local communities and conventional health workers of the health care centers, on the safe use of medicinal plants, is important to promote safer pregnancies and better health care for pregnant women and their unborn infants in Mali.

In vivo antiplasmodial and toxicological effect of Maytenus senegalensis traditionally used in the treatment of malaria in Tanzania. Malar J 2015; 14:79. [PMID: 25890324 PMCID: PMC4446455 DOI: 10.1186/s12936-014-0525-y] [Citation(s) in RCA: 18] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/12/2014] [Accepted: 12/20/2014] [Indexed: 02/07/2023] Open
Abstract
Background In Tanzania and elsewhere, medicinal plants, including Maytenus senegalensis, are still widely used in the
treatment of malaria and other ailments. The aim of the present study was to
investigate the in vivo antiplasmodial and
toxic effects in mice. Methods Oral antiplasmodial and acute toxicity of the ethanolic root extract
of M. senegalensis was evaluated in mice. The
Peters 4-day in vivo antiplasmodial effect
against early rodent malaria infection in chloroquine-sensitive Plasmodium berghei NK 65 strain in mice. Results The M. senegalensis extract was
found non-toxic and the oral median lethal dose in mice was determined to be
greater than 1,600 mg/kg body weight. The findings revealed a significant
(P = 0.001) daily increase in the level of
parasitaemia in the parasitized untreated groups and a significant (P < 0.001) dose dependent decrease in parasitaemia
in the parasitized groups treated with varying doses ranging from 25 to 100 mg/kg
body weight of M. senegalensis extract and the
standard drug sulphadoxine/pyrimethamine at 25/1.25 mg/kg body weight. Overall,
the dose dependent parasitaemia suppression effects were in the order of:
25/1.25 mg/kg body weight of
sulphadoxine/pyrimethamine > 100 mg/kg > 75 mg/kg > 50 mg/kg > 25 mg/kg
body weight of M. senegalensis extract. Conclusion The implications of these findings is that M. senegalensis ethanolic root bark extract possess potent
antiplasmodial effect and may, therefore, serve as potential sources of safe,
effective and affordable anti-malarial drugs. The displayed high in vivo antiplasmodial activity and lack of toxic
effect render M. senegalensis a candidate for
the bioassay-guided isolation of compounds which could develop into new lead
structures and candidates for drug development programmes against human
malaria.

Abstract
Traditional medicinal practices play a key role in health care systems in countries with developing economies. The aim of this survey was to validate the use of traditional medicine within local Nigerian communities. In this review, we examine the ethnobotanical uses of selected plant species from the Nigerian flora and attempt to correlate the activities of the isolated bioactive principles with known uses of the plant species in African traditional medicine. Thirty-three (33) plant species were identified and about 100 out of the 120 compounds identified with these plants matched with the ethnobotanical uses of the plants.
