This study aims to determine the effect of drying time on the yield of essential oils from orange peel (Citrus sinensis) and identify the presence of linalool compounds from essential oils. 300 grams of orange skin samples were dried at 40ºC using an oven with a drying treatment of 0 hours (fresh), 24 hours, and 48 hours. The extraction process is carried out by steam distillation method with attainment of 500 ml of distillate. Essential oils are separated from water using liquidliquid extraction (LLE), so that the essential oils are maximally obtained. The highest yield of essential oil obtained in the sample with a drying treatment for 48 hours is 0.5% (MA3), 24-hour drying obtained a yield of 0.4% (MA2) and the sample without drying provides the smallest yield of 0.2% (MA1). Identification of linalool compounds using TLC-Spectrophotodensitometry was carried out to determine the amount of linalool content seen from the AUC (Area Under Curve). AUC MA3 sample is 39475, MA2 is 35889, and MA1 is 8980. Based on the data obtained can be concluded that the drying duration of the sample affects the yield of essential oils and linalool compounds that obtained.

Hydrodistillation (HD) is a traditional technique used in most extraction processes. On the other hand, microwave-assisted hydrogen distillation (MAHD), an advanced method using microwaves in the extraction process, has recently emerged. The chemical ingredients of essential oils obtained from pomelo (Citrus grandis L.) peels obtained by MAHD and by hydrodistillation (HD) were analyzed and compared gas chromatography-mass spectrometry (GC/MS). The results show that there is no significant difference between the two methods in terms of extraction efficiency, at around 4.45 to 4.7%. The main components of essential oils were Limonene, α-pinene, β-Myrcene and Sabinene. The content of those compounds showed no clear quantitative and qualitative difference between HD and MAHD. Experimental results show that the MAHD method provides a good alternative to extracting essential oils from grapefruit, saving time, operating costs and achieving more optimal levels.

<pre>Sweet orange peel is a waste. There is a high economic valued chemical compound of essential oil called limonene which has a distinctive fresh aroma.. Essential oil of Limonene  was extracted from orange peel then will be applied as aromatherapy candles. The taking of essential oils is using distillation of liquid vapor for 3 hours. After that, the essential oil is added to aromatherapy wax and stearic acid. The volume of essential oil extracted from distillation in this study is 2,3 mL with weight 1.957 grams from 200 grams of orange peel. The addition of essential oil is 3 mL for sample 1 and 5 mL for sample 2.. The aromatherapy candles had tested for flame duration and product acceptance in the community. The result showed that the higher the content of Essential oil of Limonene  the longer the flame duration and the higher the acceptance in the community. </pre><p> </p><p><strong>Keyword</strong> : sweet orange peel, essential oil of Limonene, extraction, distillation, aromatherapy candle,</p><p> </p>

A novel microwave assisted multi-stage countercurrent extraction (MAMCE) technique was developed for the extraction of dihydromyricetin from Chinese rattan tea, Ampelopsis grossedentata. The technique combined the advantages of microwave heating and dynamic multi-stage countercurrent extraction and achieved marked improvement in extraction efficiency over microwave assisted batch extraction. Analysis of dihydromyricetin concentrations in the solvent and matrix throughout the extraction process showed that by dividing the extraction into multiple stages and exchanging of solvents between stages, steady and substantial concentration gradients were established between the matrix and solvent, thus enabling the achievement of high extraction efficiency. The yield of dihydromyricetin was significantly affected by temperature, pH, solvent/material ratio and extraction time, and optimal extraction conditions were found to be 80-100°C, at acidic pH with a solvent/material ratio of 25-30 to 1 and extraction time of 5-10 min. With the high extraction efficiency and low usage of extraction solvent, MAMCE could prove to be a promising extraction technique which can be applied to the extraction of dihydromyricentin and other bioactive substances from natural materials.
