Abstract An investigation of the petroleum ether extract from Ixeris chinensis Nakai has led to the isolation of a new compound, 3-O-acetyl-22,28-cyclobauer-7-en-3β-ol (1), together with four known compounds which have been isolated from this plant for the first time, namely taraxast-20-en-3β-ol (2), 3-O-acetyl-taraxast-20-en-3β-ol (3), taraxast-20(30)-en-3β-ol (4), and 3-O-acetyl-taraxast-20(30)- en-3β-ol (5). The structures of the isolated compounds have been elucidated on the basis of spectroscopic methods including UV, IR, ESI-MS, 1D NMR, 2D NMR techniques, and by comparison with data reported in the literature. All compounds have been evaluated for their activity against various bacteria and shown to give good results

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

Bengkoang has long been used by ancestors as a raw material for cosmetics. In Indonesia, it is usually eaten raw, sometimes with salt, lemon juice and powdered chili. However, scientific evidences that support the use of bengkoang have not been widely published. Phytosterols from the bengkoang root have been isolated and identified based on their NMR spectrum data and mass spectrum. The result of the structure elucidation informed that ß-sitosterol and stigmasterol are major components of phytosterol in bengkoang root. Phytosterol content was about 0.02% of dry weight bengkoang or 2.76 % in petroleum ether extract of bengkoang, with a ratio of ß-sitosterol and stigmasterol (65:35). Therefore, bengkoang can be further exploited as a raw material of phytosterol supplement.

1. Serial extraction of West Indian mahogany wood with selective solvents was performed. 2. The petroleum ether extract was the only fraction to exhibit promising termite-repellent activity. 3. Mahogany blocks subjected to petroleum ether extraction became susceptible to termite attack. 4. A waxy substance (P2 fraction) separated from the petroleum ether extract at times showed high termite-repellent activity. The termite-repellent principle in the P2 fraction seems to be a labile one, as the termite-repellent activity varied greatly from batch to batch. 5. The P2 fraction is a mixture of two major components and of at least a third minor one. As far as we have been able to determine this mixture, at the elemental level, contains carbon, hydrogen, and oxygen only, while esters have been the only compounds definitely characterized at the structural level.
