Tlc Analysis

Carotenoids extracted from dried peppers were evaluated for their antioxidant, analgesic, and anti-inflammatory activities. Peppers had a substantial carotenoid content: guajillo3406±4 μg/g, pasilla2933±1 μg/g, and ancho1437±6 μg/g of sample in dry weight basis. A complex mixture of carotenoids was discovered in each pepper extract. The TLC analysis revealed the presence of chlorophylls in the pigment extract from pasilla and ancho peppers. Guajillo pepper carotenoid extracts exhibited good antioxidant activity and had the best scavenging capacity for the DPPH+cation (24.2%). They also exhibited significant peripheral analgesic activity at 5, 20, and 80 mg/kg and induced central analgesia at 80 mg/kg. The results suggest that the carotenoids in dried guajillo peppers have significant analgesic and anti-inflammatory benefits and could be useful for pain and inflammation relief.

Analgesic Activities

Linum usitatissimum L is traditionally used for relief of pain and inflammation. In this study, the analgesic and anti-inflammatory effects of this plant were evaluated. Xylene test was used for anti-inflammatory evaluation in which 48 mice were randomly designated into 6 groups of 8 each including: control, dexamethasone as positive control (15 mg/kg), and experimental groups (42, 85, 170, and 340 mg/kg, respectively). For analgesic evaluation, 192 mice were randomly designated into 4 sets of 6 groups of 8 mice, including control, morphine as positive control, morphine plus naloxone, experimental groups (200 and 500 mg/kg extract), and extract along with naloxone group, which received 500 mg/kg. The analgesic activities were evaluated at 5, 15, 30, and 60 minutes, respectively, in each set. Both doses showed analgesic activity, the 200 mg/kg possessed higher effects ( P < .05). Naloxone reduced a section of its effect ( P < .001). The 170 mg/kg dose of the extract showed anti-inflammatory activity ( P < .05). The extract had phenolic, flavonoid, and flavonol compounds with antioxidant activity. Linum usitatissimum L dose dependently had analgesic activity partially like morphine and might be used as analgesic and anti-inflammatory agent.

Pyracantha Coccinea

Scarlet/red firethorn, Pyracantha coccinea M. Roem., is a common ornamental shrub, commonly cultivated nowadays in Romania and many other countries, in gardens or hedges. The tree has small white flowers and it produces small bright colored berries. The fruit is bitter and astringent, making it inedible when raw. The fruit can be cooked to make jellies, jams, sauces and marmalade. In this study, the Pyracantha coccinea M. Roem fruits from three common cultivars named �Orange Glow�, �Red Column� and �Soleil d�Or�, were collected from different individuals in Constanta city, Romania. Both frozen and dried (80�C) fruits were analyzed for the active principles content such as, carotenoids, flavonoids and total phenolic compounds correlated with antioxidant activity. Carotenoids were determined by acetone extraction and UV-Vis spectrophotometry, flavonoids, by methanol extraction and UV-Vis spectrophotometry and total phenolic, by methanol extraction, Folin-Ciocalteu reaction and UV-Vis spectrophotometry. The total antioxidant capacity was quantified through photochemiluminescence method by comparison with the standard substance used for calibration, Trolox� as tocopherol analogue (ACL procedure) using Photochem apparatus, Analytik Jena AG, Germany. The average carotenoid content in fresh frozen fruits ranged between 278-545 mg/kg (dry weight equivalent), while in dry material 133-203 mg/kg. Total flavonoids averaged 1415-4953 mg/kg in fresh fruits, increasing after heat-drying to 2981-5759 mg/kg. Fresh fruits contained a total amount of phenolic compounds of 11501-21107 mg/kg DW gallic acid equivalent, while dry fruits averaged 5749-8261 mg/kg GAE. Pyracantha coccinea M. Roem. fruits emphasized an increased antioxidant activity correlated with a high content of potentially bioactive compounds, especially of phenolic compounds, both in frozen and heat-dried state. �Red Column� and �Orange Glow� are the most promising varieties of the three cultivars, for potential pharmaceutical applications.

Purpose: To evaluate the antioxidant, anti-inflammatory and anti‐arthritic effects of the methanol extract of Tamus communis roots. Methods: The total phenolic and flavonoid contents were determined using Folin–Ciocalteu’s reagent and aluminium chloride assays, respectively while the antioxidant capacity was determined using DPPH and β-carotene/linoleate tests. For anti-inflammatory activity, carrageenan-induced paw edema in rat was used. Formaldehyde-induced paw edema and adjuvant-induced arthritis in rats were used to evaluate the anti-arthritic effect of the extract. Results: The total phenolic and flavonoid contents of T. communis showed 55.2 ± 0.036 mg GAE/g dry weight and 1.191 ± 0.002 mg QEq/g dry weight, respectively while the antioxidant activity (DPPH) showed a half-maximal inhibitory concentration (IC50 of 0.128 ± 0.011 mg/mL. Using βcarotene/linoleate assay, the extract showed 88.13 ± 4.03 % inhibition. In carrageenan-induced paw edema in rat, all doses of T. communis did not show inhibition of edema. In contrast, formaldehyde induced paw edema decreased at the dose of 150 mg/kg days 2 and 4. However, doses of 300 and 600 mg/kg did not show any activity. In adjuvant-induced arthritis, all used doses caused no reduction in arthritic scores and in paw thickness except a significant decrease with the dose 150 mg/kg at the last day. Conclusion: T. communis extract exhibits high antioxidant activity related to the phenolic compound contents. However, the results of the anti-inflammatory and anti‐arthritic studies did not support its use in folk medicine in the treatment of rheumatic ailment except on low doses

<p><strong>Abstract</strong><strong></strong></p><p>The present work examined the <em>in vitro</em> antioxidant activity of sequentially extracted, solvent extracts (Petroleum ether, chloroform and Methanol) of stem bark, leaves and callus from <em>Amoora rohituka</em>. The antioxidative capacity of the extracts were examined by using DPPH (1,1-diphenyl,2-picryl hydrazyl), ABTS (2,2’-azinobis-3-ethyl-benzothiozoline-6-sulphonic acid) and NOS (Nitric oxide scavenging) assays by using Gallic acid as standard control. Among the tested extracts, methanol extract of stem bark showed better antioxidative capacity. The total antioxidant activity was expressed as µg equivalent of Gallic acid per gram on dry weight basis. IC<sub>50</sub> values for methanol extract of stem bark were 7.53 µg/ml; 34.92 µg/ml and 56.31 µg/ml in ABTS, DPPH and NOS assays respectively. Whereas, leaves and callus extracts showed moderate antioxidative properties. </p>

Botanical Analysis

HERBACE DISSECTION is the process in which samples of herbage cut from trials are separated by hand into component species. Heavy reliance is placed on herbage dissection as an analytical tool ,in New Zealand, and in the four botanical analysis laboratories in the Research Division of the Ministry of Agriculture and Fisheries about 20 000 samples are analysed each year. In the laboratory a representative subsample is taken by a rigorous quartering procedure until approximately 400 pieces of herbage remain. Each leaf fragment is then identified to species level or groups of these as appropriate. The fractions are then dried and the composition calculated on a percentage dry weight basis. The accuracy of the analyses of these laboratories has been monitored by a system of interchanging herbage dissection samples between them. From this, the need to separate subsampling errors from problems of plant identification was, appreciated and some of this work is described here.

Verbena officinalis Linn is a traditionally known medicinal plant which is used against a number of diseases including inflammatory conditions. In this study its antioxidant activity (reducing powers, 2, 2-diphenyl-1-picrylhydrazyl (DPPH) scavenging activities), ferric reduction activity potential (FRAP), total flavonoid concentration and antimicrobial activities of 80%, 90%, 100% methanol and chloroform extracts of V. officinalis Linn root and 90% and100% methanol leaf extracts were determined. Its antioxidant activity increases with increase in amount of extract (10% to 40%v/v). Total flavonoid content (TFC) varied from 73.32±0.002 mgQE/100g of dry weight (90% methanol) to 42.39±0.032 mgQE/100g dry weight (chloroform), 2,2-diphenyl-1-picrylhydrazyl (DPPH), radical scavenging activity (%) was varied between 87.39% (90% methanol) to 45.57% (chloroform) while Ferric reducing antioxidant power was observed between 372.93±0.04 mgAAE/100 g extract (90% methanol) to 129.41±0.026 mgAAE/100 g chloroform in the root extract. The methanolic extract of the leaf showed less antioxidant activity than the methanolic extract of the root. Crude extracts of V. officinalis root showed various degree of antimicrobial activity towards drug resistance microbial pathogens. Growth inhibition tests against bacterial pathogens demonstrated concentration dependence. Moreover, gram positive bacteria were more susceptible to V. officinalis root extract when compared to gram negative bacteria. In general V. officinalis root and leave extracts possess strong antioxidant and antimicrobial activities.
