This research work was designed to extract essential oil from sweet lime peel (solid waste). The feed material selected for study is sweet lime peel. The disposal of waste product such as peels often has a legal restriction problem and treatment process involved requires higher costs. Transformation of this waste in to useful products could cut global treatment costs. Hence the objective of our experimental work was to convert sweet lime peel in to essential oil which is in huge demand in food, pharma and cosmetic industry. In our experimental work eextraction of essential oil was evaluated and comparison study was made between steam distillation, hydro-distillation, solvent extraction and hydro-steam distillation. Maximum extraction yield of 2.4 % was achieved at 90 min of contact by hydro-distillation. Hydro-distillation method offers advantages in comparison with other three methods in terms of energy saving, cleanliness and reduced waste water. Chemical constituents of essential oil samples were evaluated in terms of qualitative and quantitative analyses by gas chromatography/mass spectrometry and physical techniques. The chemical profile includes thirty two components which were identified in the extracts by Gas chromatography-Mass spectroscopy (GC-MS) analysis. The dominant component identified was limonene (65 .2 to 72.8%).

Objective: Ziziphora clinopodioides is an edible medicinal plant belongs to the Labiatae family that widespread all over Iran. It used as culinary and also in cold and cough treatments in Iran. The aim of present work was to evaluate the effect of different timeframes during the hydrodistillation on essential oil composition, antimicrobial and antioxidant activity. Materials and Methods: The essential oil of Z. clinopodiodes was extracted via hydrodistillation with Clevenger apparatus. The fractions of essential oil were captured at 6 times from the beginning of the distillation: (10, 20, 60, 120, 180 and 240 min). The fractions of essential oil were analyzed by GC/MS and their antibacterial, antifungal and antioxidant activities were studied by Disk - well diffusion and DPPH methods respectively. Results: Six distillation times and whole essential oil were captured during the hydrodistillation. Essential oil yield dropped off significantly during distillation progressed (1.0% for 10 min and 0.025 for 240 min). 1,8 Cineol, Isomenthone, Pulegone, Piperitenone and Citronellic acid were major compounds in fractions and they were affected by distillation times. Pulegone was major compound in all of essential oils. In antioxidant activity assay, whole essential oil was stronger than was stronger than positive control and fractions of essential oil, because of higher levels of Isomenthone, Piperitenone and Citronellic acid. Strongest antimicrobial activity against S. aureus, E. coli and C. albicans was observed from 10 min fraction. Conclusion: Our results indicated that distillation time can create essential oils with specific properties and we can achieve to more efficient essential oil in short times.

The essential oil of the leaves Solanum spirale Roxb. was isolated by hydrodistillation and analyzed for the first time using GC and GC-MS. Thirty-nine constituents were identified, constituting 73.36% of the total chromatographical oil components. ( E)-Phytol (48.10%), n-hexadecanoic acid (7.34%), β-selinene (3.67%), α-selinene (2.74%), octadecanoic acid (2.12%) and hexahydrofarnesyl acetone (2.00%) were the major components of this oil. The antioxidant activity of the essential oil was evaluated by using the DPPH (1,1-diphenyl-2-picrylhydrazyl) radical scavenging assay. The oil exhibited week antioxidant activity with an IC50 of 41.89 mg/mL. The essential oil showed significant antibacterial activity against both Gram-negative Escherichia coli and Gram-positive Staphylococcus aureus with MIC values of 43.0 μg/mL and 21.5 μg/mL, respectively. It also showed significant cytotoxicity against KB (oral cancer), MCF-7 (breast cancer) and NCI-H187 (small cell lung cancer) with the IC50 values of 26.42, 19.69, and 24.02 μg/mL, respectively.
