To learn differences between Chinese domestic and imported paper-process reconstituted tobacco (RT), their physical properties and chemical components were tested systemically and in-depth. The results indicated that: (1) Domestic RT were generally similar to the imported on physical properties. There were just some slight differences in filling power, combustibility (domestic RT were better than the imported), and density (the imported slightly lowered than the former). And all products were advised to improve their water contents. (2) Imported RT were higher in contents of total sugar, reducing sugar, nicotine and protein than domestic samples, whereas lower in Potassium contents; (3) Although there were no significant differences in contents of volatile alkali and total non-volatile acid between domestic RT and imported RT, volatile acid contents of the former were lower than that of the latter. Also all pH value of samples was near equal and showed very weak acidic. (4) Contents of poly-phenol, chlorogenic acid, rutin and petroleum ether extract of imported RT were higher than that of domestic products, while cellulose contents were lower. (5) The overall high contents in total sugar, reducing sugar, nicotine, volatile acids, malic acid, total poly-phenols and petroleum ether extract, may be main factors of good taste and aroma of imported products.

The seeds of Helianthus annuus have been investigated for the presence of various chemical components and biological activities with special emphasis to the anti-oxidant, antimicrobial, cytotoxic and thrombolytic assay. The results of standard phytochemical analysis revealed the presence of tannins, saponins, flavonoids, carbohydrates, steroids, fixed oils and vitamins. In vitro antioxidant activity of methanolic seed extract of H. annuus was determined by DPPH free radical scavenging assay, which demonstrated very significant antioxidant potential compared to standard antioxidant (ascorbic acid). In case of antimicrobial assay, the methanolic and ethyl acetate extract of H. annuus seeds showed high sensitivity to Salmonella typhi and moderate sensitivity to Pseudomonous aeuregenosa. The petroleum ether extract revealed high sensitivity to P. aeuregenosa. The methanolic extract of H. annuus displayed LC50 1.2 ug/ml and its petroleum ether extract showed LC50 of 1.1 ug/ml, which indicated significant cytotoxicity.Bangladesh Pharmaceutical Journal 19(1): 100-105, 2016

Phytochemical Compounds

Fruit seeds contain several phytochemical compounds which have been reported to show antiviral, anti-allergic, anti-inflammatory, anti tumor and antioxidant activities. Due to the varied chemical properties of these seeds, different solvents are used in the extraction. Therefore, this research was aimed at evaluating the effect of extracting solvents on the yield, phytochemical compounds and selected chemical properties of fermented pawpaw (Carica papaya) seed. Extracts from fermented T-solo variety of pawpaw seeds were obtained using petroleum ether, n-hexane and hot aqueous solvents using standard method. Analysis was carried out to determine some qualitative and quantitative phyto-chemical and some selected chemical composition (Peroxide Value PV and Thiobarbituric Acid Value TBA. Extracts’ yield were 26.00, 23.30 and 19.51% for petroleum ether, n-hexane and hot aqueous solvent, respectively. The result of quantitative analysis shows that all the phytochemicals were more abundant in petroleum ether extract. The PV and TBA of n-hexane, petroleum ether and hot water extract were 5.32, 4.52, 0.00 meq/kg and 0.87, 0.16, 0.09 μg/kg respectively. The PV and TBA obtained for petroleum ether extract were relatively low and         this implied that the extract will undergo little or no autoxidation or oxidative deterioration when used.

Background: The fruits with the seeds of Dracunculus vulgaris Schott. (Araceae) are used against inflammatory diseases in Turkey. Objective: Present study was designed to justify this folkloric usage type of the plant. Therefore, the aim of this study is to investigate the anti-inflammatory activity of D. vulgaris. Methods: Petroleum ether, ethyl acetate and methanol extracts were prepared from the fruits, successively. Carrageenan-, serotonin-, and prostaglandin E2-induced hind paw edema; acetic acid–induced capillary permeability and 12-O-tetradecanoyl-phorbol-13-acetate–induced mouse ear edema models were used to assess the antiinflammatory activity of the extracts. The analgesic activity was experienced by using p-benzoquinone-induced abdominal constriction test. Results: The petroleum ether extract displayed the highest activities in all of the used test models compared with the control group. Therefore, the constituents of this extract were determined by using gas chromatography–mass spectroscopy (GC–MS). Linoleic acid was found to be major constituent of the petroleum ether extract of D. vulgaris. Conclusion: This study has provided some justification for the folkloric use of the plant.

Aims: The present investigation was aimed at exploring the phytoconstituents using Gas Chromatography Mass Spectroscopy and to evaluate antioxidant and anti-inflammatory properties of the leaf extracts. Materials and Methods: The extracts were obtained sequentially with petroleum ether, ethyl acetate and water using soxhlet apparatus. The anti-inflammatory property of the identified compounds using GC- MS spectroscopy was evaluated in silico. The antioxidant activity was performed by DPPH and H2O2 method whereas anti-inflammatory study was carried out by HRBC membrane stabilization method. Terpenoids were found to be major constituents in petroleum ether extract while, phenols and flavonoids were predominantly found in ethyl acetate extract. Results and Discussion: The GC-MS analysis of the extract revealed six major molecules including Squalene, 19β, 28- epoxyleanan-3-ol and 2-tu-Butyl-5-chloromethyl-3-methyl-4-oxoimidazolidine-1-carboxylic acid. The ethyl acetate extract showed a significant antioxidant activity (P<0.01) in both DPPH method (70.87 %) and H2O2 method (73.58%) at 200 µg mL-1 . Increased membrane stabilization of petroleum ether extract was observed in the in vitro anti-inflammatory activity study. A strong relationship between the terpenoid content and anti-inflammatory activity was obtained from the correlation (0.971) and docking study. Conclusion: These results justify T. involucrata to be a rich source of terpenoids with potent antiinflammatory property.

In present investigation was carried out to screening of hair growth promoting potentiality of petroleum ether extract of Abrus precatorius leaf. Preliminary chemical tests and TLC analysis revealed the presence flavonoids and saponins. Hair growth promoting activity of petroleum ether of Abrus precatorius was screened by considering different parameters which included time taken for covering bald patch, length of hair produced, percentage of hair follicles in anagen and telogen phases, time of hair growth initiation and completion and level of minerals in blood. The petroleum ether extract of Abrus precatorius showed a very good hair growth promoting activity at a dose of 300 mg/kg which was comparable to that of 2% minoxidil. After 30 days of treatment with test and standard drugs it was observed that, time taken for covering the bald patch, hair growth initiation and completion time and quantitative hair growth were found to be comparable to that of the standard drug. An increase in percentage of hair follicles turning from telogen phase to anagen phase was noted. The control treated group of animals showed poor hair growth for all the parameters. Keywords: Abrus precatorius Linn, Anagen, Catagen, Telogen, Minoxidil
