Clausena excavata Burm. F. (Rutaceae) has long been associated with medicinal benefits in folk medicine, particularly in the treatment of cancer and its related disorders in the eastern region of Thailand. In the the present study Ultra Pressure Liquid Chromatography (UPLC) analysis of methanolic leaf extracts of Clausena excavata were carried out using short (5 cm \× 2.1 mm I.D.) columns, containing 2 m particles at very high pressures (up to 16000 psi) to obtain high efficiency separations in very short run times. The results indicate that UPLC provided better resolution compared to routine RP-HPLC. The analysis time was drastically reduced (4 min.) which is proved to be a faster and more economical analytical tool than RP-HPLC. In addition to that, the present study also evaluates anti-fungal activity against dermatophytes Trichophyton rubrum and Trichophyton mentographytes by using an agar incorporation technique. The anti-fungal activity may be due to the presence of Angelecin and gallic acid in the plant extract.

Context: A stroke or cerebrovascular disease is an abrupt onset of neurological deficit that is attributable to a focal vascular cause. Antiplatelet drugs, anticoagulants and thrombolytics are used in ischemic stroke. Indrakeeladri, is a village in Andhra Pradesh in India where traditional local practitioners prescription has long been practiced for treatment of stroke by using unknown and undisclosed formulation (gulikalu) without any name and labeling. Patients who have taken treatment at Indrakeeladri have noticed improvement in their symptoms particularly in speech. Aims: We endeavoured to analyze the formulation to know its composition as this analysis might help us in preparation of newer drugs for stroke. Settings and Design: GC MS analysis. Methods and Material: The sample was powdered and tested for its solubility in different solvents of increased polarity strength and then subjected to Gas Chromatography Mass Spectrometry (GCMS) analysis in order to know its chemical components. Results: The sample was soluble only in water. The GC-MS analysis of the test sample revealed the presence of methyl tetradecanoate, dodecanoic acid methyl ester and methyl 10-methyl undecanoate as the major constituents. These substances are known to have inhibitory effect on blood coagulation. Conclusions: Further studies need to be carried out to find out whether these components of native medicine have a role in the treatment of stroke or not.
