The complete chloroplast genome of Lessertia frutescens (L.) Goldblatt & J. C. Manning (Leguminosae), an important medicinal plant species from Southern Africa.

ABSTRACT: Lessertia frutescens (L.) Goldblatt & J. C. Manning 2000 is an endemic species of Southern Africa with high medicinal and economic values. To facilitate exploration of its genetic resource, a complete chloroplast genome was determined using Illumina pair-end sequencing technology. The complete circular genome is 122,700 bp in length with overall 34.2% GC contents. It encodes a total of 110 genes, including 76 protein-coding genes, 30 tRNA, and four rRNA genes. The maximum-likelihood (ML) phylogenetic tree indicated that L. frutescens nested within the Papilionoideae and had a close relationship with Astragalus nakaianus and A. mongholicus. The newly sequenced complete chloroplast genome will help understanding the plastome evolution, genetic diversity and contribute to the genetic conservation of the natural population of L. frutescens.

Project description:ObjectivesIndigenous medicines are widely used throughout Africa, despite a lack of scientific evidence for their safety or efficacy. The aims of this study were: (a) to conduct a pilot study of the safety of a common indigenous South African phytotherapy, Lessertia frutescens (Sutherlandia), in healthy adults; and (b) to contribute to establishing procedures for ethical and scientifically rigorous clinical trials of African indigenous medicines.DesignA randomized, double-blind, placebo-controlled trial of Sutherlandia leaf powder in healthy adults.SettingTiervlei Trial Centre, Karl Bremer Hospital, Bellville, South Africa.Participants25 adults who provided informed consent and had no known significant diseases or allergic conditions nor clinically abnormal laboratory blood profiles during screening.Intervention12 participants randomized to a treatment arm consumed 400 mg capsules of Sutherlandia leaf powder twice daily (800 mg/d). 13 individuals randomized to the control arm consumed a placebo capsule. Each participant received 180 capsules for the trial duration of 3 mo.Outcome measuresThe primary endpoint was frequency of adverse events; secondary endpoints were changes in physical, vital, blood, and biomarker indices.ResultsThere were no significant differences in general adverse events or physical, vital, blood, and biomarker indices between the treatment and placebo groups (p > 0.05). However, participants consuming Sutherlandia reported improved appetite compared to those in the placebo group (p = 0.01). Although the treatment group exhibited a lower respiration rate (p < 0.04) and higher platelet count (p = 0.03), MCH (p = 0.01), MCHC (p = 0.02), total protein (p = 0.03), and albumin (p = 0.03), than the placebo group, these differences remained within the normal physiological range, and were not clinically relevant. The Sutherlandia biomarker canavanine was undetectable in participant plasma.ConclusionConsumption of 800 mg/d Sutherlandia leaf powder capsules for 3 mo was tolerated by healthy adults.
