Purpose: To determine the phytochemical composition, acute toxicity, as well as analgesic and antiinflammatory properties of extracts of the aerial parts and callus cultures of Asteriscus graveolens.Methods: Different standard chemical tests were used for the screening of bioactive compounds in aqueous extracts of aerial parts of Asteriscus graveolens (PAE) and callus (CAE). High-performance liquid chromatography (HPLC) analysis was performed to identify the constituents of the glycosidic extract (GE). Acute oral toxicity test was carried out to ascertain the safety of the plant material. The analgesic and anti-inflammatory properties of the extracts were determined using acetic acid-induced writhing test and carrageenan-induced edema test, respectively.Results: Phytochemical analysis showed some differences in composition between the aerial parts and callus cultures. Results from HPLC analysis revealed the presence of 12 phenolic compounds in the GE of adult plants. In addition to being orally safe (no mortality), all extracts showed significant inhibition of acetic acid-induced chemical pain: PAE and GE produced 63 and 68 % reductions in pain, respectively, relative to 60.26 % pain reduction by aspirin. All extracts exerted potent anti-inflammatory effects, with PAE producing the highest effect (73 %) at a dose of 100 mg/mL.Conclusion: Asteriscus graveolens extracts possess potent pharmacological properties due to the presence of some phenolic compounds, especially flavonoids. These findings provide a scientific basis for the traditional uses of Asteriscus graveolens, and indicate that it is a potential source of antiinflammatory agents.

Withania frutescens (W. frutescens) is a medicinal plant widely used to treat several diseases. This work aims to study phytochemical composition as well as acute and subacute toxicity of W. frutescens hydroethanolic extract in mice. The phytochemical composition of W. frutescens extract was performed using gas chromatographic analysis. Acute toxicity was studied in vivo with oral administration of single doses 400 mg/kg, 1000 mg/kg, and 2000 mg/kg for 14 days. Subacute toxicity was studied with the administration of repeated doses of 400 mg/kg/day and 2000 mg/kg/day for 28 days. Phytochemical analysis of W. frutescens hydro-ethanolic extract confirmed the presence of interesting chemical compounds. Acute toxicity results showed no toxic symptoms in mice treated with an increasing dose up to a maximum of 2000 mg/kg. Alongside acute toxicity, subacute data showed no clinical symptoms nor biochemical or histological alteration in mice treated with an increasing dose up to a maximum of 2000 mg/kg compared to the control group (p < 0.05). This study shows no toxic effects in animals treated with W. frutescens extract, and, therefore, this plant can be considered safe in animals up to 2000 mg/kg under both acute and subacute toxicity conditions.

Objective: The objective of this study was to evaluate the in vitro and in vivo anti-inflammatory properties of the aqueous extract and fractions of the trunk bark of Acacia nilotica. Methods: A maceration of the powder of the trunks barks of the plant was realized. Then the aqueous macerate obtained was fractionated with dichloromethane, butanol and ethyl acetate successively. The phenolic compounds of the aqueous extract, butanol and ethyl acetate fractions were identified by HPLC/DAD. Lipoxygenase and phospholipase inhibition tests with the aqueous extract and the butanol and ethyl acetate fractions were carried out. The anti-inflammatory potential of the aqueous extract was assessed in vivo by the anti-edema test with carrageenan and the analgesic test with acetic acid at different doses (200 mg/ml; 400 mg/ml; 600 mg/ml). Aspirin (200 mg/ml) and paracetamol (200 mg/ml) were used as a reference. Results: The HPLC/DAD analysis of the extracts revealed that gallic acid is the most abundant phenol acid in the extracts. The aqueous extract inhibited lipoxygenase (IC50 = 18.32±1.18 μg/ml), phospholipase (11.44±0.32% per 100 μg/ml) and cyclooxygenase (56.48±0.29% for 100 μg/ml) as well as its tested fractions. It also reduced edema and pain in the mice by more than 50% from the 400 mg/ml dose. Conclusion: Aqueous extract of Acacia nilotica has anti-inflammatory properties. Hence its use in traditional medicine in the treatment of inflammation.

Abstract Berberis hispanica Boiss. & Reut (B. hispanica) belongs to the family Berberidaceae, which is currently used in traditional medicines. This article aimed to study the phytochemical composition and acute and subacute toxicity of B. hispanica extract in rats. The phytochemical composition of B. hispanica extract was characterized using GC-MS. The acute toxicity was investigated in vivo via the oral administration of single doses including 400, 800, 1,000, 1,200, and 1,400 mg/kg for 14 days. The subchronic toxicity was studied through oral administration of 400 mg/kg for 60 days. The findings of the phytochemical analysis of B. hispanica extract showed the presence of various phytochemical compounds. Acute toxicity results revealed serious clinical symptoms and mortalities in rats treated with 800 mg/kg up to a maximum of 1,400 mg/kg. With acute toxicity, subchronic toxicity results showed also serious signs of toxicity including biochemical and histological alterations in animals treated with 1,400 mg/kg. B. hispanica extract revealed to be toxic in rats orally treated under both subacute (>400 mg/kg) and subchronic toxicity conditions (400 mg/kg). The outcome of this study serves the society as it provides toxicological evidence of B. hispanica used in alternative medicines

Previously tested n-hexane extracts of the Scorzonera latifolia showed promising bioactivity in vivo. Because triterpenes could account for this activity, n-hexane extracts were analyzed by HPLC to identify and quantify the triterpenes as the most abundant constituents. Other Scorzonera and Podospermum species, potentially containing triterpenic aglycones, were included in the study. An HPLC method for simultaneous determination of triterpene aglycones was therefore developed for analysis of Podospermum and Scorzonera species. n-Hexane extracts of root and aerial parts of S. latifolia, ten other Scorzonera species and two Podospermum species were studied to compare the content of triterpenes. HPLC was used for the qualitative and quantitative analysis of α-amyrin, lupeol, lupeol acetate, taraxasteryl acetate, 3-β-hydroxy-fern-7-en-6-one acetate, urs-12-en-11-one-3-acetyl, 3-β-hydroxy-fern-8-en-7-one acetate, and olean-12-en-11-one-3-acetyl. Limits of detection and quantification were determined for each compound. HPLC fingerprinting of n-hexane extracts of Podospermum and Scorzonera species revealed relatively large amounts of triterpenes in a majority of investigated taxa. Lupeol, lupeol acetate, and taraxasteryl acetate were found in a majority of the species, except S. acuminata. The presence of α-amyrin, 3β-hydroxy-fern-7-en-6-one-acetate, urs-12-en-11-one-3-acetyl, 3β-hydroxy-fern-8-en-7-one-acetate, and olean-12-en-11-one-3-acetyl was detected in varying amounts. The triterpene content could correlate with the analgesic and anti-inflammatory activity of Scorzonera, which was previously observed and Scorzonera species that have been determined to contain triterpenes in large amounts and have not yet been tested for their analgesic activity should be tested for their potential analgesic and anti-inflammatory potential. The presented HPLC method can be used for analysis of triterpene aglycones, for example dedicated to chemosystematic studies of the Scorzonerinae.

Objective: The aim of the research work was to carry out the extraction of areal parts of Biden pilosa L by hydroalcholic and Hexane, ethyl acetate and acetone mixture followed by qualitative phytochemical analysis, acute oral toxicity test, anti-inflammatory test and GC-MS analysis of the extracts. Method: The hydro-alcoholic and HEA(n-hexane, ethyl acetate and acetone) extraction was done from aerial parts using ethanol and water in the ratio 70:30 and n-hexane, ethyl acetate and acetone in the ratio of 1:1:1 (HEA extract)  respectively. Acute oral toxicity testwas performed OECD guidelines. The single spot in TLC was obtained using n-hexane as solvent for HEA fraction and finally phytocomponents were identified by GC-MS present in that spot.In vitro anti-inflammatory activity was performed by human RBC membrane stabilization method. Result: The phytochemical test results obtained indicate that hydro-alcoholic extract of aerial part of Bidens pilosa L. possess alkaloids, tannins, terpenoids and saponins whereas HEA extract possess alkaloids, flavonoids, tannins. Both hydro-alcoholic and HEA extracts were found to be safe up to the dose of 2000 mg/kg BW of the mice. Both extracts showed significant in vitro anti-inflammatory activity in a concentration dependent manner. The GC-MS analysis of HEA extract of aerial parts showed the presence of the sixteen different compounds from partially separated extract from TLC plates. Conclusion: Hydro-alcoholic extract of aerial part of Bidens pilosa L. possess alkaloids, tannins, terpenoids and saponins whereas HEA extract possess alkaloids, flavonoids, tannins. Both hydro-alcoholic and HEA extracts were found to be safe up to the dose of 2000 mg/kg BW of the mice. The GC-MS analysis of HEA extract of aerial parts showed the presence of the sixteen different compounds.

We investigated the antioxidant and anti-inflammatory effects of a 70% v/v ethanol extract of the stem bark of Antrocaryon micraster on murine models of carrageenan-induced pleurisy and paw oedema. Rat pleural fluid was analysed for volume, protein content, and leucocytes, while lung histology was assessed for damage. Lung tissue homogenates were assayed for glutathione (GSH), superoxide dismutase (SOD), catalase (CAT), malondialdehyde (MDA), and myeloperoxidase (MPO). Phytochemical analysis was carried out on the stem bark. Acute toxicity studies were conducted in rats. In the pleurisy model the extract (30–300 mg/kg) significantly reduced the volume and amount of proteins and leucocytes in the exudate and also protected against lung injury. Tissue level of GSH and SOD and CAT expression were increased while MDA level and MPO activity were reduced. The peak and total oedema responses were significantly suppressed when given both preemptively and curatively in the mice paw oedema test. Saponins, alkaloids, triterpenoids, and tannins were present in the stem bark. A. micraster extract exhibited no apparent acute toxicity. We conclude that the ethanolic stem-bark extract of A. micraster has antioxidant action and exhibits significant anti-inflammatory activity through suppression of pleurisy and paw oedema induced with carrageenan.

Fumaria Capreolata

Fumaria capreolatais used in traditional medicine in North Africa for its gastrointestinal and anti-inflammatory activities. The present study investigates the effects of total alkaloids extracted from the aerial parts ofFumaria capreolata(AFC) on LPS-induced production of proinflammatory mediators (IL-6, IL-1β, iNOS, TNF-α, COX-2, and MIP-2) in RAW264.7 cells. AFC significantly reduced the inflammatory response inhibiting the production of nitric oxide (NO) and IL-6 in a dose-dependent manner, without affecting the viability of cells, and downregulated mRNA expression of proinflammatory key players: IL-6, IL-1β, iNOS, TNF-α, and COX-2. AFC antinociceptive and anti-inflammatory properties were also evaluated on the acetic acid- and formalin-induced pain models in mice. AFC oral administration significantly inhibited acetic acid-induced writhes and reduced formalin-induced paw licking time. Therefore, AFC may be a potential candidate for the treatment of inflammatory diseases, such as colitis and arthritis.

The tea of aerial parts of Smilax larvata Griseb. (Smilacaceae) has been ethnopharmacologically used in Southern Brazil due to its anti-inflammatory action. In this study, ethanolic and organic extracts from aerial parts of S. larvata were phytochemically and pharmacologically characterized. The phytochemical analysis of EtOAc extract of S. larvata revealed the presence of three flavonoids, drabanemoroside, kaempferol 3-O-α-L-rhamnopyranosyl(1→2)-α-L-rhamnopyranoside, and kaempferol, the first two being isolated for the first time in this genus, two phenolic compounds p-hydroxybenzoic acid and p-coumaric acid, and alkaloids. In vitro assays demonstrated a potential antioxidant property of SLG. The treatment with SLG induced a significant reduction of the formalin-evoked flinches in rats, an effect reversed by opioid antagonist naloxone. Treatment with SLG also induced a significant increase in the hot plate latency and a decrease of intestinal motility by 45%. No effect was observed over nociceptive responses induced by a TRPA1 agonist mustard oil or over acetic acid-induced writhing in mice. Together, our data suggested that SLG has an in vivo antinociceptive effect, which seems to be associated with the opioid system activation. These findings support previous claims of medical use of Smilax larvata in the treatment of pain conditions.
