Summary
Sarcocephalus latifolius (syn. Nauclea latifolia), known as the African pincushion tree, is a West African plant used in traditional medicine for treating malaria, pain, and various other illnesses [PMID:27346294, PMID:36281909].
Background
Sarcocephalus latifolius (also known as Nauclea latifolia) is a shrub or small tree found in tropical areas of Africa [PMID:20822326, PMID:24506054, PMID:27346294].
Traditional uses
It is widely used in folk medicine to treat malaria [PMID:36281909, PMID:27114686, PMID:25794802], epilepsy [PMID:27346294, PMID:20822326], pain (including muscle, joint, and neuropathic pain) [PMID:27346294, PMID:29098206, PMID:24263011], anxiety [PMID:20822326], fever [PMID:20822326, PMID:21600276], hypertension [PMID:29098206], hepatitis [PMID:29098206], jaundice [PMID:29098206], and rheumatism [PMID:29098206]. The leaves are traditionally used by the Fulanis in Nigeria to deworm animals [PMID:32697959].
Active compounds
The plant contains indole alkaloids such as strictosamide, angustoline, nauclefine, angustidine, and naucleidinal [PMID:11547422, PMID:36281909]. Other identified compounds include betulinic acid, ursolic acid [PMID:38326823], flavonoids, phenolics, glycosides, and tannins [PMID:32256953]. While tramadol was previously reported as a natural phytochemical in the roots, subsequent research confirmed it is an anthropogenic contamination from synthetic drug administration to cattle in Cameroon [PMID:25219922, PMID:26473295].
Mechanism of action
Indole alkaloids from N. latifolia promote LDL uptake in HepG2 cells by inhibiting PCSK9 [PMID:30668438]. Betulinic and ursolic acids may mediate antimalarial activity through docking with PfEMP-1 and PfPKG proteins in Plasmodium falciparum [PMID:38326823]. Leaf extracts exhibit inhibitory activities against alpha-amylase and alpha-glucosidase [PMID:32256953].
Clinical evidence
Evidence DPain/Nociception
Root decoction produced significant antinociceptive activity in animal models [PMID:20822326]; alkaloid fractions exhibited potent anti-hyperalgesic and anti-allodynic effects in rat models of neuropathic pain [PMID:24263011].
Evidence DMalaria
Strictosamide displayed moderate antiplasmodial activity against Plasmodium falciparum [PMID:11547422]; root extracts showed in vivo antiplasmodial effects in P. berghei-infected mice [PMID:38326823].
Evidence DHypertension/Fertility
Ethanol root extract lowered high blood pressure in hypertensive Wistar rats [PMID:40156777].
Evidence DCoccidiosis
Root extracts exhibited oocyst sporulation inhibition (75.85%) in vitro [PMID:39195799].
A mixture of S. birrea, N. latifolia, and P. longum ameliorated memory impairment and protected striatal neurons in T2D rat models [PMID:37821784, PMID:37441190].
Evidence D
Safety & adverse effects
Hydromethanolic extracts of N. latifolia exhibited significant clastogenic/aneugenic activity in Chinese Hamster Ovary cells [PMID:21600276]. In chicken embryos, root extracts caused toxico-pathological effects [PMID:39515114].
Evidence summary
The current evidence is primarily based on in vitro studies and animal models (Level D), with no human clinical trials provided in the abstracts. There is strong phytochemical evidence for the presence of indole alkaloids and a clear correction regarding the synthetic origin of tramadol in certain samples.
