The present study was conducted to evaluate the stem bark and leaf of Sterculia diversifolia for larvicidal, leishmanicidal, insecticidal and anthelmintic activities. In the larvicidal activity, dichloromethane and ethyl acetate fractions of both stem bark and leaf showed significant results, while the ethyl acetate fraction showed mild activity (IC50: 70.09 ± 0.09 μg/mL; 71.25 ± 0.01 μg/mL). In the insecticidal activity of the stem bark, n-hexane fraction showed mild activity (20-40% mortality) against all three subjects, while the insecticidal activity of leaf, methanolic extract and n-hexane fractions showed moderate activity (60% mortality) against Rhyzopertha dominica and Callosobruchus analis. In the anthelmintic activity of stem bark and leaf, ethyl acetate fraction exhibited activity in a dose-dependent manner giving time of paralysis and death shorter followed by dichloromethane fraction with 200 mg/mL concentration. Hence, it is clear that S. diversifolia stem bark and leaf possess larvicidal, leishmanicidal, insecticidal and anthelmintic agents.

Background: The prevalence of diabetes mellitus is increasing on a global trend. The aim of the present study is to identify the most effective antioxidants and hypoglycemic fraction of Azanza garckeana. Methods: The fractions (nhexane or ethyl-acetate or aqueous) of A. garckeana were administered to the alloxan-induced diabetic rats at doses of 100, 200, and 400 mg/kg for 15 days. Antioxidants activities were evaluated at concentrations of 62.5, 125, 250, and 500 µg/mL using the DPPH scavenging assay. Results: Results revealed that both the hexane, ethyl-acetate, and aqueous fractions exhibited hypoglycemic and antioxidants activities in a dose-dependent manner. The n-hexane fraction demonstrated highest percentage DPPH scavenging effect of 26.34±3.43, 38.44±4.35, 59.34±3.45, and 74.83±5.35 at 62.5, 125, 250, and 500 µg/mL respectively. The ethyl-acetate fraction demonstrated 19.33±2.98, 28.94±3.24, 47.34±2.90, and 57.82±4.54 respectively while the aqueous fraction exhibited the least activities of 12.45±23.45, 18.64±2.94, 27.94±3.89, and 39.43±3.89 at concentrations of 62.5, 125, 250, and 500 µg/mL respectively. In addition, the n-hexane fraction demonstrated the most significant hypoglycemic effect with the highest glucose reduction of 58.97 ±3.45 %, 63.86±5.35 %, and 66.51±4.35 %, ethyl acetate fraction demonstrated glucose reduction of 7.55±0.54%, 21.77±2.35 %, and 29.56±3.46 % while the aqueous fraction demonstrated the least hypoglycemic effect of 9.89±2.67 %, 18.09±3.45 %, and 18.87±3.24 at 100, 200 and 400 mg/kg bw respectively. Conclusion: The n-hexane fraction of Azanza garckeana extract could serve as a reservoir of bioactive agents that could be useful for the development of a new anti-diabetic agent

Albizia adiantifolia (Schumach) W.F. Wright (Fabaceae) is a plant used traditionally in treating different health ailments which includes worm infections. The essential oils (EOs) were obtained by hydrodistillation in an all glass Clevenger apparatus, and characterized by gas chromatography (GC) and gas chromatography-mass spectrometry analysis (GC-MS). In vitro petri-dish anthelmintic activity was carried out using adult earthworm, Eudrilus eugeniae. The leaves, stem bark and root bark EOs afforded a total of 40, 26 and 20 constituents representing 90.9%, 94.1% and 90.9% of the total oil fractions respectively. The classes of compounds identified in the leaves, stem bark and root bark are oxygenated monoterpenes (4.1%, 1.7% and 4.0% respectively), sesquiterpene hydrocarbons (39.5%, 67.3% and 42.6% respectively), oxygenated sesquiterpenes (18.7%, 22.3% and 30.1% respectively), non-terpene derivatives (12.1%, 2.6% and 14.2% respectively) and apocarotenoids (16.5% and 0.2% in the leaves and stem-bark). β-caryophyllene (23.0%), E-geranylacetone (7.4%), acorenone (6.4%), viridiflorol (6.4%), α-zingiberene (6.3%) and ar-curcumene (4.6%) were the major constituents in the leaves oil, β-caryophyllene (39.3%), selin-11-en-4-α-ol (10.4%), α-zingiberene (9.6%), ar-curcumene (7.2%), caryophyllene oxide (6.4%) and α-humulene (5.6%) were the major constituents in the stem bark oil, while β-caryophyllene (32.1%), selin-11-en-4-α-ol (13.1%), caryophyllene oxide (8.4%), pentadecanal (6.1%) and α -humulene (4.4%) were the major constituents in the root bark oil. β -caryophyllene dominated the oils. The leaf EO was the most active against E. eugeniae worm. All the oils showed a relatively higher activity compared to Albendazole, in a concentration dependent manner. There was significant difference (p<0.001) in activity.

Ostericum Koreanum

Ostericum koreanummaximowicz (Umbelliferae), a medicinal herb in Korean Oriental Medicine, has been applied to treat cold, headache, neuralgia and arthralgia. The ethyl acetate fraction ofO. koreanumroot was subjected toin vitroantioxidant activity with different methods for free radical scavenging activities. In addition, the cell viability and nitric oxide release assays were performed here for the first time in neuroblastoma (Neuro-2a) cell cultures. Among all the tested methods, the ethyl acetate fraction was expressed very active, exhibiting a good Trolox equivalent values and IC50, comparable to that of the commercial antioxidants, Trolox and ascorbic acid, respectively. The results showed that there was a reduction of cell viability by the fraction in a concentration dependent manner. These results suggest thatO. koreanumshows good antioxidant activitiesin vitroby inhibiting free radicals. These findings provide a rationale for thein vivotesting. Also, the major constituents behind the antioxidant mechanisms of this fraction warrant further study.

Hedyotis diffusa Willd and Scutellaria barbata D. Don (HDSB) were the core couplet in medicines that were commonly used for the purpose of anti-inflammation and anticancer treatments in China. However, biological properties of this couplet have not been fully elucidated. In this study, we screened fractions of HDSB for their anti-inflammatory activities and explored pertinent molecular mechanisms on murine macrophage RAW264.7 cell model. Ethyl acetate fraction from the aqueous extract of the couplet at equal weight ratio (EA11) showed the strongest inhibition of the nitrite accumulation in supernatant of RAW264.7 cells stimulated with lipopolysaccharide (LPS)/interferon-γ (IFN-γ). In addition, EA11 inhibited iNOS and IL-1β expression in a concentration-dependent manner while promoting the expression of HO-1 and PPAR-γ. Anti-inflammatory capability is most likely facilitated by its inhibitory effect on JNK signaling pathway and miR-155 expression. This study suggests that EA11 may be represented as a potential anti-inflammatory therapeutic candidate.

Songi (Dillenia serrata) is a tree endemic to Southeast Sulawesi and its stem bark been used in folk medicine. Nonetheless, only a handful scientific knowledge regarding chemistry and biological activities has been investigated on the plant. The present study aimed to investigate the antioxidant and xanthine oxidase (XO) inhibitory activity of the stem bark of the plant. Methanol extract and organic fractions (petroleum ether, ethyl acetate, and methanol) of the dried powdered stem bark of songi were evaluated for phytochemical screening, total phenolic (TPC), total flavonoid contents (TFC), DPPH, FRAP, and XO in vitro assays. Flavonoids, tannins, terpenoids, steroids, and saponins present in the extract. TPC and TFC in extract were 59.2 mg GAE/g and 23.4 mg QE/g. The contents in organic fractions were in solvent-dependent manner (methanol>ethyl acetate>petroleum ether). Extract and fractions scavenged DPPH radicals (48.2–59.7%) at 100 μg/mL compared to ascorbic acid, trolox, and gallic acid (90.3–93.8%). FRAP values varied from 0.8–3.4 μg/μg equivalent trolox amount (quercetin and gallic acid were 25.7 dan 32.4 μg/μg, respectively). They also inhibited xanthine oxidase (15.3–50.3%) at 100 μg/mL (allopurinol, 98.2%). The study concluded the potential of methanol extract and organic fraction of the stem bark of songi, thus highlighted the prospect of songi to be used in herbal and drugs development from nature.

Angiogenesis has essential role in growth and metastasis of tumors. Development of therapies aimed to suppress angiogenesis using medicinal plants is one of the effective approaches for prevention/treatment of cancer. The current study was performed to investigate in vitro anti-angiogenic effect of Teucrium Polium (TP) extract and its fractions. The aerial part of Teucrium Polium was powdered and extracted with 50% ethanol. The extract was fractionated in to aqueous (AQ), n-butanol (BU), ethyl acetate (EA) and n-hexane (HE) fractions. Anti-angiogenic effect of TP was examined on human umbilical vein endothelial cells (HUVECs) in three-dimensional collagen matrix. The endothelial cells form capillary-like branches that can be visualized using phase contrast microscope and the number of tube-like structures can be quantified as a measure of in vitro angiogenesis. Furthermore, anti-proliferative and vascular endothelial growth factor(VEGF )suppressive effect of TP as important factors in the process of angiogenesis were assessed using3-(4,5-dimethyl-thiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT)and quantitative ELISA, respectively. Based on our findings, among the TP fractions, EA fraction showed the highest inhibitory activity on angiogenesis. This fraction with IC50: 68 µg/mL, inhibited angiogenesis at 60 µg/mL. The crude extract and other fractions of TP inhibited angiogenesis in a dose-dependent manner at doses higher concentrations than EA fraction, significantly.TP extract and EA fraction were able to inhibit proliferation of HUVEC and inhibited VEGF secretion in a dose dependent manner. The ethyl acetate fraction at 60 µg/ml inhibited VEGF secretion perfectly. Our data indicated that ethyl acetate fraction of Teucrium Polium could be a potential candidate for the prevention of angiogenesis in cancer and other related disorders. However, this suggestion needs more quantitative and in vivo investigations for confirmation.

Nephroprotective Effect

<p>The present study was conducted to explore the protective effect of <em>B. baluchistanica</em> against gentamicin-induced renal toxicity in rabbits. Phytochemical investigations lead to the isolation of berberine and palmatine. The crude hydro-methanolic extract at various doses (100, 200 and 300 mg/kg body weight) elicited strong nephroprotective effects by restoring various biomarkers which were deranged by gentamicin  such as creatinine, urea, serum uric acid levels (p&lt;0.001) in plasma and urine output creatinine clearance, urinary protein and γ-glutamyl transferase level (p&lt;0.001) in urine in a dose dependent manner. The mediators involved in oxidative stress such malondialdehyde, reduced glutathione, glutathione peroxidase, and catalase levels were significantly (P˂0.05-0.001) modulated in kidney tissue homogenate. Correspondingly, there is a significant (P&lt;0.05) recovery in kidney weight and % loss in body weight compare to GM group. From these results, it is possible that<em> B. baluchistanica</em> exhibited protective effect mediated through the presence of berberine  and palmatine.</p><p><strong>Video Clip of Methodology:</strong></p><p>Histopathology:   7 min 24 sec   <a href="https://www.youtube.com/v/VNa-fDMRosA">Full Screen</a>   <a href="https://www.youtube.com/watch?v=VNa-fDMRosA">Alternate</a>  </p>

<p class="1Body">Post-harvest losses are recognized to be one of the critical constraints upon food security among farmers of poor resource in Africa.The use of botanical pesticides in pest management during storage against insects is often encouraged because synthetic insecticides produce multiple side-effects on human health and environment. Insecticidal activity of the hexane, dichloromethane, ethyl acetate and methanol extracts of bark of <em>Trichilia gilgiana</em> was tested on <em>Sitophilus zeamaïs</em>, <em>Tribolium castaneum </em>and <em>Rhyzopertha dominica</em>. The mortality rate was measured variable. The results of analysis showed that the mortality rate has a very highly significant variation following extracts, doses, insects and time considered (<em>P </em>&lt; 0.001). Extracts with ethyl acetate and hexane of <em>Trichilia gilgiana</em> are effective against <em>S. zeamais </em>at the highest doses (1 g/ 10 mL and 0.5 g/10 mL of solvent). These effective extracts were characterized by gas chromatography coupled with mass spectrometry. Molecules such as 2-Oxazalidone; thiocyanic acid; Methanethioamide, N,N-dimethyl; 2-Coumaranone and other were characterizated. These results may consolidate traditional use of <em>Trichilia gilgiana</em> in pest management<em>.</em></p>

<p class="Abstract">Anti-snake venom therapy is the only treatment for snake bite but leads to acute and chronic conditions which may be severe. The medicinal plants have gained importance over years to find an effective alternative to anti-snake venom. The present study focused on evaluating the potential of <em>Clerodendrum serratum</em> for the anti-snake venom activity. Phytochemicals were extracted from the <em>C. serratum</em> with different solvents. The ethyl acetate and methanolic extracts were found to neutralize the major enzyme toxins (phospholipase A<sub>2</sub>, protease and hyaluronidase) of <em>Bungarus caeruleus</em> and <em>Daboia russelii</em> venom at a concentration of 100 µg/mL. The fibrinogenolytic activity of both the venoms were neutralized. The study proves that the plant <em>C. serratum</em> possesses certain compounds which inhibit the toxins present in the venom of <em>B. caeruleus</em> and <em>D. russelii</em>.</p><p class="Abstract"><strong>Video Clip of Methodology</strong>:</p><p class="Abstract">Hyaluronidase assay:   3 min  30 sec   <a href="https://www.youtube.com/v/Xz5C6bbwgW0">Full Screen</a>    <a href="https://www.youtube.com/watch?v=Xz5C6bbwgW0">Alternate</a></p>
