AbstractStylophorum lasiocarpum (Oliv.) Fedde (Papaveraceae) belongs to traditional Chinese medicine herbs but there was minimal information on the content of alkaloids in this plant. Extracts from the aerial part and roots were examined by liquid chromatography with UV and mass spectrometric detection, with nineteen alkaloids identified. Changes in alkaloid content over the entire vegetation period of a one- and two-year old plant were studied. The protoberberine alkaloids, coptisine and stylopine, were found to be the main substances in extracts of the aerial part irrespective of the plant’s age and time of harvest. Variable amounts of protopine, sanguinarine, chelerythrine, chelirubine, macarpine, chelilutine and berberine were also recorded in the aerial part. The roots contained significantly larger quantities of all alkaloids than the aerial part with the levels of most alkaloids varying from May to October, peaking in the middle of the vegetation period. Coptisine was the dominant alkaloid in all samples. The antiproliferative activities of the root extract and of seven individual alkaloids were tested on A375 human malignant melanoma cells. The significant dose-dependent toxicity of the root extract was attributed largely to the quaternary benzo[c]phenanthridine alkaloids, macarpine and sanguinarine.

The methanol extract of Raphanus sativus root extract showed a protective effect on paracetamol-induced hepatotoxicity in a dose-dependent manner. Degree of lipid peroxidation caused by paracetamol was measured in terms of thiobarbituric acid reactive substances (TBARS) and protection was measured in reference to serum glutamate oxaloacetate transaminase (SGOT), serum glutamate aspartate transaminase (SGPT), and blood and hepatic levels of antioxidants like glutathione and catalase. Administration of extract along with paracetamol showed significant protection. Levels of TBARS were found to be low, activities of SGOT and SGPT were low, while hepatic glutathione levels were significantly higher in experimental rats that received the mixture of paracetamol and the extract as compared to rats that received paracetamol only. Activities of catalase were also high in all experimental groups. Thus this study indicates the involvement of Raphanus sativus root extract with antioxidants like glutathione and catalase in rendering protection against paracetamol-induced lipid peroxidation and hepatotoxicity.

Salacia Reticulata

The purposes of this study were to investigate the inhibitory effects of Salacia reticulata Tul. root extract on cellular oxidants and melanogenesis in B16 melanoma cells. Cells treated with non-toxic doses of S. reticulata root extract were investigated for their effects on melanogenesis, cellular tyrosinase activity and cellular oxidant scavenging activity. The results indicated that S. reticulata extract inhibited melanin synthesis and tyrosinase activity in α-MSH-induced or UV-irradiated B16 melanoma cells in a dose dependent manner. Additionally, the extract also exhibited anti-cellular oxidants in UV-induced radical melanoma cells. Altogether, these results suggested that S. reticulata root extract has roles in suppression of melanogenesis and oxidant inhibition. S. reticulata root extract may be a potential source for the development of pharmaceutical products for treatment of skin hyperpigmentation disorders.

Abstract: Rheumatoid arthritis is an inflammatory autoimmune disorder.: CIA rats were treated by using three doses of WSAq (100, 200, 300 mg/kg b. wt., orally) and methotrexate (MTX, 0.25 mg/kg b. wt. i.p.) as a standard reference drug for 20 days. The anti-arthritic effect was assayed by measuring the arthritic index, autoantibodies such as rheumatoid factor (RF), anti-cyclic citrullinated peptide antibody (a-CCP), anti-nuclear antibody (ANA), anti-collagen type II antibody (a-CII) and inflammatory marker like C-reactive protein (CRP). The oxidative stress parameters were also measured.: Treatment with WSAq resulted in a dose-dependent reduction in arthritic index, autoantibodies and CRP (p<0.05) with maximum effect at dose of 300 mg/kg b. wt. and the results were comparable to that of MTX-treated rats. Similarly, oxidative stress in CIA rats was ameliorated by treatment with different doses of WSAq, as evidenced by a decrease in lipid peroxidation and glutathione-: The results showed that WSAq exhibited antioxidant and anti-arthritic activity and reduced inflammation in CIA rats and suggests the potential use of this plant in the treatment of arthritis.

Tragopogon graminifoliusDC. (TG), Compositae family, is traditionally used for the treatment of various diseases like gastrointestinal and hepatic disorders. The aim of the present study is to standardize extracts from TG used for preparation of different dosage forms in traditional Iranian medicine (TIM) based on phenolic compounds. For this purpose, total phenolic content and some phenolic compounds were determined in ethanolic extracts from aerial part and root of TG by HPLC method. Furthermore, antioxidant activity was evaluated using DPPH-HPLC methods. Caffeic acid, gallic acid,ρ-coumaric acid, ferulic acid, and catechin were detected in root and aerial part of TG.ρ-Coumaric acid (6.357 ± 0.014 mg·g−1) was dominant phenolic compound in aerial part followed by ferulic acid (1.24 ± 0.018 mg·g−1). Also,ρ-coumaric acid (2.685 ± 0.031 mg·g−1) was highly abundant in root, followed by catechin (2.067 ± 0.021 mg·g−1). Antioxidant activity of root extract (460.45 ± 0.78 µg Vit.E.E·mL−1) was better than that of aerial part. Generally, phenolic compounds are one of the major constituents of TG and could be used as markers for standardization of dosage forms prepared from this plant. Also, TG demonstrated significant antioxidant activity using DPPH-HPLC method. Phenolic compounds of TG may be responsible for its marked antioxidant properties.

In this study there were evaluated total phenolic and flavonoid contents, and ferric reducing antioxidant power (FRAP)of 3 herbs species, that are commonly used in fresh stage (summer savory –Satureja hortensisL., marjoram –Majorana hortensisM. and thyme –Thymus vulgarisL.) in dependence on time of harvest. The total flavonoid content ranged from 2.36 to 4.10 g of catechin equivalents (CE).100g−1of dry weight (dw) of plant material. The highest average total flavonoids content was ascertained in aerial part of summer savory colected in first harvest (4.10 g CE.100g−1dw) and the lowest in aerial part of summer savory collected in third harvest (2.36 g CE.100g−1dw). The highest total flavonoid content was measured by all tested species in plant material harvested in first time of harvest. The highest total phenolic content was estimated in plant material of marjoram harvested in the second time of harvest (6.74 g gallic acid equivalents (GAE).100g−1dw) and the lowest in aerial part of summer savory harvested in the third time of harvest (4.16 g GAE .100g−1dw). Ferric reducing antioxidant power (FRAP) ranged from 1,13 (summer savory, harvest No. 3) to 1.91 g GAE .100g−1dw (thyme, harvest No. 1). The best results of total flavonoid content, total phenolic content and FRAP were obtained by marjoram. Among harvest times there were the highest contents of measured compound mainly by the samples collected in the first time of harvest.

Infertility is a serious issue disturbing reproductive ages in all society now and calling for solution for continuity. Infertility were induced on groups of animals with separate sexes; M, M1, M2 and M3; F, F1, F2 andF3 with daily subcutaneous administration of 20 mg/kg body weight tramadol HCl for 42 days before respective ethanol root extract administrations of (500, 1000, 1500) mg/ kg body weight for 10 days. The animals were anaesthetized and sacrificed; uterus, ovaries, testes, epididymis were dissected out for histomorphological studies. There is evidence of dose treatment of infertility among treated groups. From the organ weight study, both the male and the female organ weight in the groups remained significantly unchanged. There are dose dependent treatments with the male and female tramadol treatment. The result is more pronounced in the increased dose of ethanol root extract (1000 mg/kg and 1500 mg/ kg) body weight treated testicular cells. This study indicated that Morinda lucida has a prophylactic effect against tramadol-induced testicular damage.

The aporphine alkaloid magnoflorine, known as a constituent of Asian Epimedium species, was isolated for the first time from the wild growing European species, Epimedium alpinum L. Identification was done by comparison with literature data. The HPLC method was applied for the determination of the content of the alkaloid in methanolic extracts of plant material. The underground part of E. alpinum contains 1-2 % of magnoflorine, while its content in methanolic extracts was 9.2-11.8 %. The aerial part of the plant contains less alkaloid (0.06-0.12 %), while the magnoflorine content in methanolic extracts of the aerial part was 0.4-0.8 %. Probably, the high content of magnoflorine in the methanolic extracts of underground parts of E. alpinum influences its dose-dependent cytotoxic activity (300 ?g/ml; 39 % survival of cells in an experimental K562 cell culture).

Aqueous Root Extract

Aim: The study is aimed at investigating the antinutritive effects of aqueous root extract of Moringa oleifera on haematological indices following sub-chronic consumption of alcohol in Wistar rats. Methods and Materials: Thirty (30) experimental rats weighing 100-120 g were randomly divided into 6 groups of 5 rats each. Group 1, the normal control group was given just rat feed and water, group 2, negative control was administered alcohol only (1.5 ml/kg body weight), rats in group 3, 4 and 5 received combined administration of alcohol 1.5 ml/kg body weight and 200, 400 and 600 mg/kg body weight of aqueous root extract of Moringa oleifera respectively, group 6 rats were administered 250 mg/body weight of extract only. At the end of fourteen days (14) the experimental rats were then sacrificed, and blood was collected for haematological analysis. Results: The result obtained shows a dose-dependent response in almost all the parameters, white blood cell (WBC) count increases significantly(P<0.05) with 600 mg/kg while dose 200 mg/kg and 400 mg/g shows no significant change. Red blood cells (RBC) decreases non-significantly (P<0.05) with increased amount of aqueous Moringa root extract.  Likewise, there was also a dose-dependent decrease in the haematological count and more noticeable with 200 mg/kg dose. It was also observed that mean corpuscular haemoglobin concentration (MCHC) and mean corpuscular volume (MCV) increases in all the treatment groups with significant observed in 400 mg/kg and 600 mg/kg. The increase in alcohol can bring about suppression of the blood cells production, enhance if there is reduction in the red blood cells, it, therefore, implies that the will be reduction in the oxygen-carrying capacity of the red blood cells, that would be carried to the tissues as well as the level of carbon dioxide returned to the lungs. Also, the PCV is involved in the transport of oxygen and absorption of the nutrient. Therefore, increase in PCV, shows a better transportation and thus results in an increase in both primary and secondary polycythemias. Conclusion: This research work shows that the plant extract contains some bioactive component or phytochemical constituents that are capable of ameliorating the toxicity effect of alcohol on animal models.
