Sterculia foetida oil contains cyclopropene fatty acids namely 8,9-methylene-heptadec-8-enoic acid (malvalic) and 9,10-methylene-octadec-9-enoic acid (sterculic) to an extent of 50-55%. The present study reports the preparation of biodiesel from S. foetida oil using sodium hydroxide as catalyst. The resultant biodiesel was evaluated for physico-chemical properties namely iodine value (72.6), free fatty acids (0.17%), phosphorous content (0 ppm), flash point (179°C), cloud point (3°C), pour point (3°C), viscosity at 40°C (4.72 cSt), oxidative stability at 110°C (3.42 h), density (0.850 g/cm 3 at 15°C), and trace metals (Group I metals 0.21 ppm). The properties were compared with that of sunflower, soybean and rapeseed oil-based biodiesels and found to be comparable except for the pour point.

Background: Polycystic ovary syndrome (PCOS) represents the most common endocrine dysfunction in women of reproductive age and it is considered a heterogeneous and complex disorder that can impact many organ systems. Women with PCOS have higher prevalence of early pregnancy loss. Beside fertility problems, metabolic and psychological complications include insulin resistance, diabetes, hypertension, metabolic syndrome, depression are at high level in women with PCOS. However, there is evidence that lifestyle intervention limits the PCOS. Therefore, our objective is to evaluate the complications and to check quality of life improvement in PCOS women. Material and methods: Females of 15-45 years diagnosed with PCOS were included in our study. Results: Among 150 patients recruited in our study, 21-25 years age group females were highly affected with PCOS. Most of the women were with short-term complications which includes infertility, menstrual dysfunction. After frequent ultrasound scanning and general approach with the patient 50% of complications subsided due to regular medication, diet and exercise. Conclusion: From this study we conclude that to maintain Lifestyle intervention along with regular medicine improve the quality of life in PCOS women.
