Andrographis Paniculata

Background: Andrographis paniculata is a herbaceous plant in the Acanthaceae family, that is widely used as a traditional medicine in Asian countries and known to exhibit a wide range of pharmacological effects. Recent studies have provided an overview of the great potential of A. paniculata as an analgesic. The ethanol extract and ethyl acetate (EA) fraction of A.paniculata were shown to contain diterpene lactone compounds, which may be useful as a potential active ingredient in analgesic drugs. The development of a herbal medicine based drug requires an effective and high quality active ingredient. Therefore, this research was aimed to compare the analgesic activity of ethanol extract and EA fraction based on their andrographolide content and further to determine the more viable active substance for analgesic herbal medicine based drug development. Method: The andrographolide content in the ethanol extract and EA fraction was determined by High Pressure Liquid Chromatography (HPLC). Measurement of analgesic activity was performed by writhing test. The experimental animals were randomly divided into eight groups consisting of 5 mice in each. Group 1 (negative control) received 1% Tween-80 in normal saline. Group 2 (positive control) received a standard analgesic drug (diclofenac sodium) at a dose of 40 mg/kg body weight. Group 3, 4, and 5 received ethanol extract while Group 6, 7, and 8 received EA fraction, each at a dose of 12.5, 25, and 50 mg andrographolide/kg body weight, respectively. Each mouse was injected intraperitoneally with 1% acetic acid at a dose of 10 ml/kg body weight 30 minutes after oral administration of the treatments. The number of writhes were counted 5 min after acetic acid injection over a period of 45 min. Results: Andrographolide content in ethanol extract and EA fraction was 15.66±0.28 and 21.25±1.08 % w/w, respectively. Ethanol extract and EA fraction displayed analgesic activity of 67.68% and 70.91% respectively, at a dose of 50 mg andrographolide/kg body weight. The positive control at a dose of 40 mg/kg body weight showed an analgesic activity of 74.33%. Statistical analysis showed no significant differences between EA fraction at a dose of 50 mg andrographolide/kg body weight and ethanol extract at the same dose as well as the positive control (P> 0.05). The effective dose 50% (ED50) of the ethanol extract and EA fraction was determined to be 29.49 and 25.55 mg/kg body weight, respectively. Conclusion: It was possible to use andrographolide content as an indicator for the analgesic activity of A.paniculata. Ethanol extract and EA fraction of A. paniculata at the same dose of andrographolide showed similar analgesic activity. The amount of ethanol extract which needed to reach similar analgesic activity was higher than EA fraction. Therefore, EA fraction likely has greater potential as an analgesic active substance due to its higher content of andrographolide; however further study is needed to develop it as a dosage form.

The sunflower seed is the seed of the sunflower (Helianthus annuus). The methanol extract of seeds of Helianthus annuus were screened for analgesic activity in mice model to systematically explore the medicinal values of the plant. Acetic acid induced writhing and hot plate methods were used to confirm the central and peripheral analgesic action. In case of acetic acid-induced writhing test the extract showed significant (P <0.05) analgesic potential at doses 100 and 200 mg/kg body weight (50.35 and 57.85% inhibition, respectively). In the hot plate method, increase (p < 0.05) of latency period was also observed in comparison to standard aspirin. At 60 minutes, the latency period of two different doses (100 and 200 mg/kg body weight) was found at 13 ± 0.91 and 16.5 ± 1.55 second. The results obtained support the use of Helianthus annuus seeds in painful conditions acting both centrally and peripherally.Islam et al., International Current Pharmaceutical Journal, March 2016, 5(4): 38-40http://www.icpjonline.com/documents/Vol5Issue4/02.pdf

The aim of this study was to phytochemically investigate the ethanolic extract of Hibiscus sabdariffa Linn. calyces and to evaluate the analgesic, anti-microbial and anti-diarrheal activities of this. The calyces of Hibiscus sabdariffa were separated from the other plant parts and sun dried and extracted using ethanol and phytochemically and pharmacologically evaluated.Different Phytochemical tests were performed for phytochemical screening and for determining the functional groups. Different methods like Disc diffusion method for antimicrobial activity determination, Castor oil induced diarrhea in mice method for the antidiarrheal study and Acetic acid induced writhing test for analgesic activity were employed. Phytochemical screening of the calyces of Hibiscus sabdariffa ensured the presence of alkaloid, flavonoids, saponins, tannins in the crude ethanolic extract. The peripheral analgesic activity was evaluated by acetic acid induced Writhing method. The extract produced 66.85% (p< 0.001) inhibition of writhing in mice at the dose of 500-mg/kg body weight, which is comparable to diclofenac sodium (78.45% (p<0.001) at the dose of 25mg/kg). The anti-diarrheal activity of the crude extract of Hibiscus sabdariffa was evaluated using the model of castor oil induced diarrhea in mice. The crude etanolic extract of Hibiscus sabdariffa (calyces) showed a marked antidiarrhoeal activity at dose of 500 mg/kg-body weight as compared to the standard antidiarrhoeal agent loperamide (dose:50mg/kg-body weight). Hibiscus sabdariffa caused an increase in latent period i.e. delayed the onset of diarrhoeal episode and decreased the frequency of defecation. Anti-microbial activity was tested using a number of micro-organisms. The peripheral analgesic activity of the ethanolic extract of the calyces of Hibiscus sabdariffa against acute inflammatory pain was significantly high as compared to potent inhibitory activity of Diclofenac (25mg/kg). Therefore, it is likely that the ethanolic extract at a dose of 400mg/kg might suppress the formation of these substances or antagonize the action of these substances and thus exerts its analgesic activity in acetic acid-induced writhing test. Anti-diarrheal activity was present in the ethanolic extract (500mg/kg) which indicate that the drug in decreased intestinal motility. This plant sample didn’t show any antimicrobial activity.

Background: Pain and inflammation are the basic processes involved in the pathogenesis of many diseases. Non-steroidal anti-inflammatory drugs are often used to treat rheumatic diseases. The study compound N-Benzoyl Isoserine Methyl Ester (N-bime) is a newly synthesized propionic acid derivative by National Chemical Laboratory, Pune. Since the biological data of this compound is not available, the present study has been planned to screen this compound for anti-inflammatory, analgesic activity and its toxicity profile in animals.Methods: Single dose toxicity study was carried out in rats. Anti-inflammatory activity was tested by Rat Hind Paw Oedema and Cotton Pellet Implantation method. For Analgesic activity, Acetic acid induced writhing and Tail Pinch method was used. Yeast induced Pyrexia was used for evaluation of anti-pyretic activity. Ibuprofen was the positive control. Data are presented as mean±SEM. Statistical analysis was performed by analysis of variance and students unpaired‘t’ test.Results: The test compound N-bime did not show any apparent adverse effects or mortality in the dose range 1mg - 500mg / 100gm body weight in animals. It showed better anti-inflammatory actions in higher doses as compared to Ibuprofen (p˂ 0.05). In acetic acid induced writhing test N-bime offered better protection against writhes, than Ibuprofen. But, both failed to demonstrate analgesic activity in the Tail Pinch method. N-bime showed a gradual decrease in temperature in the anti-pyretic test (P<0.001).Conclusions: The present study indicates that N-bime does possess anti-inflammatory, analgesic and weak anti-pyretic properties like the NSAIDs. It has proved to be safe in the dose range of 1mg - 500mg / 100gm body weight in rats and mice.
