Introduction: Many modern medicines used today based on plants and plant products. Piper betle is generally known as the betle vine, it is an important medicinal and recreational plant. High performance thin layer chromatography (HPTLC) is an advanced powerful analytical method with more separation power, high performance and superior reproducibility than classic thin layer chromatography (TLC). A chromatographic fingerprint of a plant extract is a chromatographic pattern of some common chemical constituents of pharmacologically active and/or chemical characteristics. Chromatographic fingerprints are useful in authentication and identification of plant. Objectives:  Objectives of present research was to establish HPTLC fingerprinting of methanolic extract of Piper betle L. leaves. Materials and Methods: Methanolic extract of Piper betle leaves was prepared using soxhlet apparatus. HPTLC studies were performed using a CAMAG HPTLC system equipped with automatic TLC sampler-4 (ATS 4), TLC scanner 4, and vision CATS 3.0 software. Results: The study revealed the presence of alkaloids with Rf value 0.65, flavonoids with Rf values 0.19, 0.29, 0.72, 0.95., and phenolic compound with Rf value 0.7. Conclusion: The HPTLC fingerprinting profile developed for the methanolic extract of Piper betle L. leaves will help in proper identification of the plant.Piper betle

Abstract Background: Understanding area-specific knowledge, attitudes, practices and demographic risk factors towards malaria is becoming critical for designing appropriate awareness and control strategies. Methods: A cohort of respondents from 243 randomly selected households across 3 villages in eastern Tanzania was assessed using a standard questionnaire and direct observation.Results: Fifty-three percent of respondents cited Anopheles mosquitoes that were responsible for transmitting malaria, and 85% of those explicitly cited female Anopheles mosquitoes. The rest (47%) knew that malaria is transmitted by a mosquito but could not name it. Commonly cited mosquito breeding sites were water bodies (75%) and rubbish (24%). Majority (61%) knew that the under-fives were most vulnerable to malaria. ITNs were mostly (64%) cited as a means of malaria control. Commonly cited malaria mosquito entry routes were windows (46%), eave opening (10%) and opening on the walls (4%). Majority (70%) confirmed malaria at the health facility. The rest (30%) relied on symptoms. Majority (96%) preferred modern antimalarials. Seventy-nine percent of the respondents owned at least one ITN. Cooking was done predominantly (77%) outdoors, finished cooking and went to bed after 20:00h. Most (58%) respondents still attended night-time outdoor communal gatherings without malaria protection. Conclusions: The current study indicate that majority of participants were aware that Anopheles mosquitoes were responsible for transmitting malaria, they bred in water, under-five children were most vulnerable to malaria, and ITNs constituted the most deployed control measure. Most respondents preferred confirming malaria at the health facility and treatment with modern antimalarials. Yet, the rate of self-diagnosis and self-medication, as well as inappropriate use of bednets requires great improvement. Demographic risk factors for early- and/or outdoor-transmission included night-time outdoor cooking and attending communal gatherings without malaria protection. The findings warrant a subsequent study to show a causal link between night-time outdoor activities, vector biting patterns and malaria prevalence.

Alhagi maurorum (A. maurorum) is one of the medicinally important plants belonging to the family leguminasae, commonly known as camel thorn. This research was amid to identify the chemical compounds in the aerial part of A. maurorum using GC-mass analysis. Three solvents with different polarities were used for the extraction of chemical constituents (water, methanol and petroleum ether). The results of GC-MS analysis led to identification of various compounds. In total, thirty-nine compounds from petroleum ether extract, thirty-two compounds in methanolic extract and seventeen compounds in aqueous extract were identified. Majority of the identified compounds have been reported to possess many biological activities. Among them, we reported 10 new anticancer compounds (Vitamin E; Hexadecanoic acid; Stigmast-5-en-3-ol; Phytol,2-hexadecen-1-ol,3,7,11,15-tetramethyl; Squalene; Hexadecanoic acid; 2-hydroxy-1-(hydroxymethyl) ethyl ester; Oxime,methoxy-phenyl,methyl N-hydroxyben-zenecarboximidoate; Ergost-5-en-3-ol; 9,12- Octadecad-ienoic acid and Farnesol) from A. maurorum using three solvent, while the best effective solvent was petroluem ether. Therefore, we report that A. maurorum has great potential to be developed into anticancer drugs.

Effective Use

Lippia nodiflora has been traditionally used for treatment of knee joint pain. Hitherto, no studies have been reported on the effective use of L. nodiflora against hyperuricemia, gout or other metabolic disorders. In this present study, L. nodiflora was examined for its ability to lower uric acid levels using an in vitro xanthine oxidase inhibitory assay. The whole plant methanolic extract was subjected to bioactivity-guided fractionation to yield 4 fractions (F1–F4). F3 displayed the highest potency and was further purified by column chromatography to afford two phenylethanoid glycosides, arenarioside (1) and verbascoside (2), and three flavonoids, 6-hydroxyluteolin (3), 6-hydroxyluteolin-7- O-glycoside (4), and nodifloretin (5). These compounds inhibited xanthine oxidase activity, with IC50 values between 7.52 ± 0.01 and 130.00 ± 2.25 μM, of which 3 was the most potent. In contrast, allopurinol, serving as a positive control, was 0.22 ± 0.00 μM. Thus, L. nodiflora, and its chemical constituents are worthy of further studies as potential anti-hyperuricemic agents.

Abstract Background Gunnera tinctoria has been collected by Mapuche-Pewenche people for food and medicinal purposes. The high polyphenol content of methanolic extract from G. tinctoria leaves with chemical constituents such as ellagic acid and quercetin derivatives suggests its application to prevent endothelial dysfunction and oxidative stress. The aim of this study was to provide evidence of the protective effect of this extract on endothelial function by reducing oxidative stress induced by high d-glucose and H2O2, as well as by stimulating nitric oxide (NO) levels in human umbilical vein endothelial cells (HUVECs). Results A methanolic extract with a high content of polyphenols (520 ± 30 mg gallic acid equivalents/g dry extract) was obtained from G. tinctoria leaves. Its main constituent was ellagic acid. The results of Ferric reducing antioxidant power and 2,2-diphenyl-1-picrylhydrazyl radical scavenging assays of the extract confirmed its antioxidant activity by inhibition pathway of radical species. The incubation of HUVECs with the extract decreased the apoptosis and reactive oxygen species (ROS) synthesis induced by high extracellular concentration of d-glucose or hydrogen peroxide. The extract increased endothelial NO levels and reduced vasoconstriction in human placental vessels. Conclusions This study provides evidence about the antioxidant and endothelial protective properties of methanolic G. tinctoria leaf extract. The extract improves the availability of NO in HUVECs, inhibiting the production of ROS and vasoconstriction.

Isolation And Characterization

Pistacia integerrimais one of twenty species among the genusPistacia. Long horn-shaped galls that develop on this plant are harvested and used in Ayurveda and Indian traditional medicine to make “karkatshringi”, a herbal medicine used for the treatment of asthma and different disorders of respiratory tract. However, until now, the molecular mechanisms of action of “karkatshringi” and its chemical characterization are partially known. This study deals with the isolation and characterization of the active constituents from the methanolic extract ofP. integerrimagalls and it was also oriented to evaluatein vitroandin silicotheir potential enzymatic inhibitory activity against phosphodiesterase-1 (PDE1), a well-known enzyme involved in airway smooth muscle activity and airway inflammation. Our results showed that the methanolic extract ofP. integerrimagalls and some of its active constituents [naringenin (1) and 3,5,7,4′-tetrahydroxy-flavanone (2)] are ablein vitroto inhibit PDE1 activity (59.20 ± 4.95%, 75.90 ± 5.90%, and 65.25 ± 5.25%, resp.) and demonstratein silicoan interesting interaction with this enzymatic site. Taken together, our results add new knowledge of chemical constituents responsible for the biological activity ofP. integerrimaand contextually legitimate the use of this plant in folk medicine.
