Accumulating evidences have reinforced the use of medicinal plants in the treatment of various ailments as a result of negative side effects associated with conventional drugs. Plant components such as phenols and flavonoids with antioxidant potential have confirmed protective roles against oxidative stress-induced degenerative diseases like diabetes mellitus (DM). The current study was carried out to investigate the effect of seed pod ethanol extract from Copaifera salikounda (SPEECS) in alloxan-induced diabetic rats. SPEECS was obtained by maceration of seed pod powder in absolute ethanol for 72 h, filtered, concentrated and dried in-vacuo. Gas chromatography-mass spectrometry (GC–MS) technique was used to quantitatively elucidate the chemical constituents of SPEECS. Twenty-four male albino rats were randomly allocated into four groups (n=6): normal control, DM control, DM + 200 mg/kg SPEECS and DM + 400 mg/kg SPEECS groups. DM was induced in the Wistar albino rats through intraperitoneal injection of 200 mg/kg body weight of alloxan. After 14 days of treatment, the body weight changes and the fasting blood glucose level were determined in the different groups. Also, serum biochemical parameters such as alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), albumin (ALB), total protein (TP), malondialdehyde (MDA), superoxide dismutase (SOD) and catalase (CAT) were estimated. The GC-MS results confirm nine bioactive compounds with 9-octadecenoic acid (55.75%) being most abundant. SPEECS (200 and 400 mg/kg) administration significantly (P 0.05) caused gain in weight, decreased fasting blood glucose and reversed the elevated liver function enzymes (ALT, AST, ALP) while total TP and ALB were markedly elevated relative to DM control group. Furthermore, SPEECS attenuated the activities of SOD and CAT while the level of MDA was significantly (P 0.05) decreased in dose dependent manner in comparison to the DM control. This study indicated that SPEECS can alleviate hyperglyceamia of DM. Key words: Copaifera salikounda; oxidative stress; medicinal plants; diabetes mellitus; phytochemicals; orthodox ANTIDIABETIČNI UČINEK EKSTRAKTA ETANOLA Copaifera salikounda (HECKEL) NA SLADKORNO BOLEZEN, SPROŽENO Z ALLOXAN-om, PRI PODGANAHIzvleček: Obstaja vedno več dokazov, ki poudarjajo uporabnost zdravilnih rastlin pri zdravljenju različnih bolezni, tudi zaradi različnih negativnih stranskih učinkov, povezanih s konvencionalnimi zdravili. Rastlinske sestavine kot so fenoli in flavonoidi z antioksidativnim potencialom, imajo po nekaterih raziskavah zaščitno vlogo pred degenerativnimi boleznimi, ki jih povzroča oksidativni stres, kot je sladkorna bolezen diabetes mellitus (DM). Študija je bila izvedena z namenom raziskovanja učinka etanolnega semenskega ekstrakta iz rastline Copaifera salikounda (SPEECS) pri podganah s sladkorno boleznijo, ki jo je povzročil alloxan. SPEECS je bil pridobljen z maceracijo praška semen v prahu v absolutnem etanolu 72 ur ter nadaljnjo filtracijo, koncentracijo in sušenjem v vakuumu. Za kvantitativno ugotavljanje kemijskih sestavin SPEECS je bila uporabljena tehnika plinske kromatografije in masne spektrometrije (GC-MS). Štiriindvajset samcev podgan Wistar je bilo naključno razporejenih v štiri skupine (n=6): normalna kontrola, kontrola DM, DM + 200 mg/kg SPEECS in DM + 400 mg/kg SPEECS. DM je bil pri podganah sprožen z intraperitonealno injekcijo 200 mg/kg telesne mase alloxana. Po 14 dneh zdravljenja so bile pri različnih skupinah določene spremembe telesne teže in nivo glukoze v krvi (na tešče). Poleg tega so avtorji raziskave izmerili še nekatere serumske biokemične parametre kot so ravni alaninske aminotransferaze (ALT), aspartatne aminotransferaze (AST), alkalne fosfataze (ALP), albumina (ALB), skupnih proteinov (TP), malondialdehida (MDA), superoksiddismutaze (SOD) in katalaze (CAT). Rezultati GC-MS so v izvlečku SPEECS pokazali devet bioaktivnih spojin, v katerih je največ 9-oktadecenojske kisline (55,75%). SPEECS (200 in 400 mg/kg) je povzročil znatno (P 0,05) povečanje telesne mase, znižanje glukoze v krvi na tešče in znižal raven encimov pokazateljev jetrne funkcije (ALT, AST, ALP), medtem ko je bila raven TP in ALB pri podganah, ki so prejemale SPEECS izrazito povišana v primerjavi z DM kontrolno skupino. Zdravljenje s  SPEECS je tudi oslabilo aktivnosti SOD in CAT, medtem ko se je raven MDA znatno zmanjšala (P 0,05) v primerjavi s kontrolno skupino DM. Ta študija je pokazala, da lahko SPEECS ublaži hiperglikemijo pri sladkorni bolezni pri podganah.Ključne besede: Copaifera salikounda; oksidativni stres; zdravilne rastline; sladkorna bolezen; fitokemikalije; ortodoksni

Objective:Traditionally prepared infusions and decoctions are commonly used in the management of diabetes mellitus, in southern Nigeria; one of such is the aqueous extract of the sclerotia of Pleurotus tuberregium (“usu” milk). In this study, the effects of the extract on the body weights, tissue/ organ weights, fasting blood glucose, blood/plasma lipid profiles and atherogenic indices were investigated in normal and alloxan-induced diabetic rabbits.Methods:Diabetes mellitus was induced by the injection of alloxan (120 mg/kg body weight) via the marginal ear vein. The extract was administered orally at 100, 200 and 300 mg/kg to normal and diabetic rabbits; while metformin was administered at 50 mg/kg. The crude extract was analyzed by gas chromatography, coupled to flame ionization detector.Results:Thirty-one known flavonoids were detected, consisting mainly of isoquercetin (28.5%), luteolin (24.3%), quercetin (18.8%) and kaempferol (11.3%). Sitosterol (82.0%) and stigmasterol (12.5%) were the most abundant of the seven phytosterols detected. Compared to the diabetic control, the treatment significantly (p<0.05) lowered the weights of the kidney and liver, as well as the levels of blood glucose and triglyceride, plasma VLDL, LDL and non-HDL cholesterol, atherogenic index of plasma, cardiac risk ratio, atherogenic coefficient and Castelli’s risk index II. It, however, significantly (p<0.05) increased plasma HDL cholesterol, without significantly affecting blood total cholesterol levels.Conclusion:This study showed that the extract was hypoglycemic, and improved lipid profile and atherogenic indices, thus highlighting its cardioprotective potential, thereby supporting its use in the management of diabetes mellitus.

The search for antimalarial compounds has been necessitated by the resistance of Plasmodium falciparum to almost all antimalarial drugs. The aim of this research was to determine in-vitro antimalarial activity of extracts of some indigenous plants species in Kebbi State. Plant extraction was carried-out by maceration using ethanol and water as solvent. The antiplasmodial activity of the extracts was evaluated against fresh clinical isolates of P. falciparum using WHO method of in-vitro micro test. Phytochemical screening was also carried out on the extract to deduce the active chemicals present in the plant extract. All plant extracts demonstrate dose dependent antimicrobial activities with IC50 Less than 50%. However highest growth inhibition of the P. falciparum was demonstrated by aqueous and ethanol extract of A. indica with IC50 7.4µg/ml and 8.6µg/ml respectively followed by ethanol and aqueous extract of C. occidentalis with IC50 15.3µg/ml and 18.0µg/ml respectively. Least antimalarial activity was demonstrated by aqueous extract of M. oleifera with IC50 33.5µg/ml while ethanolic extract of M. oleifera demonstrated IC50 of 20.50µg/ml. M. indica ethanolic and aqueous extract also demonstrated moderate antimalarial activity with IC50 18.8µg/ml and 24.5µg/ml. The phytochemical screening of medicinal plants showed the presence of tannins, saponins, alkaloids, flavonoid, phenol and cardiac glycosides in the extracts, which may be responsible for the antiplasmodial activity. This result justifies the traditional use of the plant in malaria treatment and further research is suggested to identify and characterize the active principles from the plants.

Diabetes mellitus is a chronic disorder, inherited or acquired, characterised by the incapacity of the body to control the levels of blood glucose. The most common initial symptoms of hyperglycemia are: weight loss, lethargy, polyuria, polydipsia, polyphagia. Treated incorrectly, diabetes can lead to blindness, neuropathy, nephropathy, kidney failure and coronary heart disease. In type 2 diabetes mellitus, besides administrating a classic treatment with oral agents, it is very important that the pacients follow a balanced and strict diet and hidrate themselves correctly. New drugs have been approved and introduced in therapy in Europe and USA in the last years, with reduced risks and higher benefits, but with the limitation of high costs. The SGLT-2 inhibitors (ertugliflozin, dapagliflozin, canagliflozin) have an independent action against insulin, therefore they can be associated with other oral agents, aiming to grow the pacients’ compliance, but also the effects of the farmacotherapy. Oral co-administration in fixed combination with DPP-4 inhibitors, such as sitagliptin, saxagliptin and not only reduces blood glucose, but it will also mutual reduce renal, pancreatic and cardiovascular side effects.

Medicinal plants play significant roles in the prevention of human beings from various pathogenic microorganisms and diseases. The immunomodulators are agents used to modulate the immune system and can be obtained from both natural as well as synthetic origin from plants and chemicals. Alteration within the system is often achieved by immunomodulatory agents from a plant source, low molecular weight compounds like alkaloids and other nitrogen-containing compounds, terpenes, phenols, and high molecular weight compounds like lectins, polysaccharides. The Immune system is a part of the body to detect the pathogen by using a specific receptor to produce an immediate response by the activation of immune components cells, cytokines, and chemokines and also release of an inflammatory mediator. This review also discusses various ethnopharmacological information of traditional medicinal plants being used as immunomodulators.

Many people choose alternative medicines for Diabetes Mellitus (DM) disorders, such as herbal plants to suppress the occurrence of the disease widely. In general, DM occurs when the pancreas doesn't produce enough insulin, or when the body can't effectively use the insulin which it produces. The use of medicinal plants to treat various diseases has shown minimal side effects. Indonesia is one of the countries that has used plants as traditional medicine since ancient times. In Indonesia, thousands of species of medicinal plants have been studied to address health problems. Among the medicinal plants that have been studied is the Neem plant (Azadirachta indica A. Juss) which has been shown to cure various diseases. This review article describes the potential of the Neem plant as an antidiabetic. The results of this literature review, in the form of Neem herbal extracts, have quite good potential as an antidiabetic because they contain several compounds such as meliacinolin, azachdirichtin, gliserid oil, acetyl oxyturanoe acid and other compounds that can also act as antidiabetic.
