The purpose of this paper is to carry out phytochemical investigations of different extracts of Eucalyptus globulus bark such as aqueous, methanolic and supercritical carbon dioxide fluid extract (SCFE) with ethyl acetate as entrainer. Three fractions (Eu 8, 9 and 10) containing steroidal δ‐lactone were isolated from SCF extract and the structure of Eu‐10 was earlier determined on the basis of NMR, HPLC‐MS, X‐Ray crystallography.

Column chromatography led to the isolation of flavonoids, tannins, steroids, etc. in different solvent systems. Isolated steroidal lactone (Eu‐8,9&10) of Withanolide series were tested for the presence of total phenolic content, total flavonoid content and the results were expressed as gGAE/100 g (TPC), and gQE/100 g (TFC), respectively. The antioxidant capacity was evaluated based on their ability to scavenge free radicals generated from ABTS, DPPH, FRAP and H₂O₂ by spectrophotometric method.

The result of the present study showed that different extracts of E. globulus bark and the isolated fractions, exhibited different antioxidant activity. This was due to the fact that they contained different amounts of flavonoid and phenolic compounds as per their ability to solubilize these compounds; the high scavenging property of E. globulus may be attributed to hydroxyl groups existing in the phenolic compounds. All the samples exhibited different extent of antioxidant activity (AOA) and showed higher potency when compared with BHT in scavenging action of DPPH free radical. Comparative data analysis showed SCF extract to be better than methanolic and aqueous extracts, both in terms of yield and AOA, while Eu‐10 was the best amongst purified fractions.

The present research has serious implications on identification of natural antioxidants from E. globulus. Natural antioxidants with better structure‐activity relationship are under investigation. Isolation of withanolide from Eucalyptus bark has opened newer horizon for its use.

Collection of Eucalyptus bark from the forest (a forest waste) by women folk can be a source of revenue generation and thus has social implication as well. It is an important agro product.

The steroidal lactone (Eu‐10) showed highest radical scavenging effect even at IC50, thus the isolated lactone proved to be the best potential scavenger of free radicals amongst all crude extracts and the isolated fractions.

The purpose of this paper is to evaluate the experience of visitors with the Janadriyah festival.

An on-site intercept survey was conducted among a random sample of visitors of the festival. The survey was conducted by two field researchers between February 10 and February 25, 2014. A self-administered questionnaire was distributed only to those who agreed to respond to the survey. Out of 200 questionnaires distributed, 28 were incomplete and thus eliminated from the study. As a result, 172 questionnaires were accepted for the purpose of final analysis, representing a response rate of 86 percent.

There is a statistically significant contribution for both the first motivation (I participate in the Janadriyah festival to increase my cultural knowledge) and the fifth one (I participate in the Janadriyah festival to see new and different things and to enjoy a unique atmosphere). There is a statistically significant relationship between the most of services provided and the level of satisfaction. As well as, there is a statistically significant relationship between the perception and the level of satisfaction, also with the word of mouth communication. Finally, the results shown that behavioral intention had a positive influence on word of mouth communication.

There were time limits to this study as the research was conducted during the organization of the Janadriyah festival during its 26th session (February-March 2014).The research was also limited by place as it was conducted at the capital of Saudi Arabia, Janadriyah province.

The model of the study could be applied in similar studies for different festivals all over the world.

Increasing the promotional efforts to attract more visitors from different regions in the world. As it is observed that the vast majority of participants in the Janadriyah festival are local residents. In addition, there is a need to organize training programs to all staff participating in the organization of the festival supervised by academics and professionals. Organizing seminars during the festival in order to increase the awareness of local residents with importance of the cultural heritage and how to keep it. And at the end, the program of the festival has to be updated from one session to another in order to attract more attendees.

The integrated model of the study represent an added value to the research in the field of tourism festivals.
