Introduction: Oxidative stress in the brain causes nervous system impairment. Hence the use of antioxidants could be an effective approach to prevent disorders such as anxiety. Plants containing phenolic constituents are reported to be potent antioxidants. Brassica oleracea L. commonly known as broccoli, is rich in phenolics mainly flavonoids and possesses excellent antioxidant property, however its anxiolytic potential has not been investigated. Thus in the present study antianxiety activity of extracts of broccoli was evaluated in experimental animals. Materials and Methods: Various pharmacognostic parameters of the plant material were studied following standard procedures. Groups of six mice each were taken as different treatment groups. Control group received vehicle (1\% Carboxy Methyl Cellulose), positive control received Diazepam (2mg/kg) as standard drug while test groups received petroleum ether and hydroalcoholic extracts (50, 100 and 200 mg/kg body weight, p.o.). The effects were evaluated on Elevated Plus Maze (EPM), hole board and mirror chamber tests. Statistical analysis was performed using ANOVA, followed by Turkey\’s post-hoc test. Results: Hydroalcoholic extract shows dose dependent increase in the average time spent and frequency of entries in the open arms of the EPM; decreased latency, increased time spent and frequency of entries in the mirror chamber; increased number of head dips in hole board test as compared to control was observed. These effects were comparable to the effect produced by diazepam. Phytochemical screening of the bioactive extract revealed the presence of alkaloids, phenols, flavonoids and tannins. Conclusion: From our study, it can be concluded that hydroalcoholic extract of Brassica oleracea at the dose of 200 mg/kg possesses marked anxiolytic activity.

Nyctanthes arbortristis L. (Oleaceae) or \“night jasmine\” is cultivated for its fragrant flowers and is widely used in traditional systems of medicine as an anthelmintic, cholagogue, laxative and antimalarial. The plant has been studied pharmacognostically and certain standards are available. However there are no reports on HPTLC quality assessment of Nyctanthes arbortristis. Hence the present study involves the development of qualitative HPTLC fingerprint profile of n-hexane, ethyl acetate, methanol extracts of leaves of N. arbortristis followed by quantitation of marker compounds \â-sitosterol, \â-amyrin in n-hexane extract and caffeic acid in ethyl acetate extract. The developed methods were used for comparison of plant extracts with a few commercial formulations containing N. arbortristis. These HPTLC methods can be used easily for evaluation of quality of plants collected from different sources as well as for commercial formulations containing N. arbortristis.

Key words: Nyctanthes arbortristis, commercial formulations, HPTLC qualitative and quantitative evaluation.
