Herbal medicines are important in treatment of inflammation as they are safe and nontoxic. Tannins are important bioactive compounds used as anti-inflammatory agents and possess wound healing potential. Anti-inflammatory activity of tannins extracted from seedling leaf tissue and callus culture extracts of Achyranthes aspera L. and Ocimum basilicum L. were determined using Carrageenan induced paw edema model. Wound healing potential of tannins from callus cultures of leaf explants of both plants were evaluated using four models in rabbits i.e. excision, incision, dead space and burn wound. Group I acted as control, Group II treated with Povidone iodine as standard drug. Groups III and IV were experimental groups treated with creams which consisted of tannins of callus cultures of leaf; cream A (A. aspera) and cream O (O. basilicum). The results of anti-inflammatory activity of callus cultures of leaf explants were comparable with standard drug Indomethacin. Seedling leaf tissue and callus culture extracts of A. aspera and O. basilicum plant showed decrease in paw edema thickness, size and maximum percentage inhibition of paw edema respectively. Among four wound models burn wound showed the best wound contraction by Cream O. Hydroxyproline content and tensile strength of dead space and incision wounds exhibited good result also respectively. Cream O exhibited best results as compared to cream A. Histopathological examination showed that cream O showed faster rate of fibroblast and collagen formation as compared to cream A. The results showed that condensed tannins of callus cultures of leaf of A. aspera exhibited the best anti-inflammatory activity while tannins from callus cultures O. basilicum showed the best results for wound healing. These findings may enable use of both plants for formulation of new phytomedicine.Current outbreak of dengue has shown serious health concerns in Pakistan. The present study reports the anti-dengue potential of Carica papaya natural compounds. The leaves of C. papaya have previously shown promising results in cure of Dengue fever. The aim of this project is to find specific bioactive compounds by computational screening and biological activities of C. papaya against serine NS2B, NS3 and NS5 proteases of dengue virus. Docking study resulted in the screening of nine bioactive compounds having highest docking scores. However, three compounds namely epigallocatchin, catechin and protocatechuric acid had the strongest binding affinity with the active residues i.e., Ser135, His51 and Asp75 of dengue virus serine proteases. Results also indicated that the extract of C. selleck chemical papaya was a strong antimicrobial and antioxidant agent. It is concluded that the C. papaya compounds can be commercially applied for medical formulations against dengue virus.Fast dissolving orodispersible film (ODF) was prepared for concurrent administration of biopharmaceutical classification system (BCS) class II drugs, i.e., meloxicam (MX) and tizanidine (TZ), using natural (xanthan gum), semisynthetic (hydroxypropyl methylcellulose and hydroxyethyl cellulose) and synthetic (polyvinyl alcohol) polymers. Compatibility of the ingredients of ODFs was ascertained through Fourier transform infra-red spectroscopy and differential scanning calorimetry. ODFs were characterized through disintegration time, pH of the surface of film, tensile strength, folding endurance, % elongation and content uniformity (MX and TZ) which were found in the range between 17±1.3-56±3.1 s, 5.11±0.07-6.28±0.05, 14.721±1.2-33.084±3.1 N/m2, > 100, 3.33±0.53-10.04±0.77 % and 98.01-99.34 % (MX) and 97.48-99.03 % (TZ), respectively. The values of moisture uptake, moisture loss and loss on drying of all formulations were in the range from 1.06±0.09-7.51±0.93 %, 0.06±0.01-2.3±0.08 % and 0.008±0.002-0.03±0.03 %, respectively. In vitro drug release study in simulated saliva fluid of pH 7.4 has shown that > 90 % MX and TZ was released within 5 min. Visual inspection, scanning electron microscope and X-ray diffraction analysis of all ODFs expressed their smooth surfaces. ODF prepared from xanthan gum (F5) exhibited better physicochemical and mechanical properties as compared to other formulations.This study elicits the underlying mechanism(s) of Capparis decidua when used for different gut disorders. HPLC chromatogram of C. decidua extract (CD.Cr) and its respective fractions showed a variety of phytochemicals of which, kaempferol being in a high proportion. In mice, CD.Cr at doses of 70 and 150 mg/kg enhanced the wet feces output to 33 and 44% respectively as compared to carbachol (47.6%), while doses of 500 and 700 mg/kg, presented 41 and 70% safety against castor oil-driven diarrhea, respectively. Its flavonoid constituent, kaempferol at doses of (50 and 100 mg/kg) produced 51.7 and 82% safety when compared to nifedipine which provided 95% safety at dose of 40 mg/kg against castor oil-driven diarrhea like loperamide. In isolated jejunum preparations, C. decidua extract and its respective fractions (except pet-ether) produced atropine-sensitive inhibitory effects, whereas kaempferol and nifedipine showed atropine insensitive effects. Against high K+-induced contractions, C. decidua's fractions and kaempferol both exhibited a concentration-related non-specific inhibition while displacing the Ca++ -CRCs to right-ward with suppression in maximal response like nifedipine. In isolated rat ileal preparations, CD.Cr and respective fractions elicited atropine-sensitive gut excitatory responses. In summary, this article reports C. decidua's laxative effect through cholinergic receptor activation as well as its antidiarrheal effects, where its flavonoid constituent kaempferol produces Ca++ antagonist like activity, thus justifying C. decidua folk use in constipation and diarrhea.Owing to its traditional applications, the current study focuses on Ajuga parviflora (A. parviflora) leaves extract for phytochemical and pharmacological analysis. The principle constituents were identified through gas chromatography (GC), and gas chromatography/mass spectroscopy (GC/MS), these includes phthalic acid, squalene, α-tocopherol, vitamin E, phytol, 2-methylenecholestan-3-ol, stigmasterol, cholest-22-ene-21-ol and 3,5-dehydro-6-methoxy. Hepatoprotective effect of A. parviflora was evaluated through isoniazid and rifampicin (INH and RFP) induced hepatotoxicity in rat. Animals in group A were treated with INH and RFP 50 mg/kg. Animals in group B, C, and D were pre-treated with A. parviflora extract at 100, 200 and 300 mg/kg dose prior drug administration. A. parviflora extract at 200 and 300 mg/kg in group C and D significantly reduced aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), and bilirubin (p less then 0.001) as compare to group B (100mg/kg). Total protein (TP) was also significantly (p less then 0.
