<p>In this study, the essential oil (EO) of lemongrass (<em>Cymbopogon citratus</em>) or “lemon tea” leaves was studied. The EO was obtained by the steaming (0.75 ± 0.05%) and distillation (1.5 ± 0.07%), assisted by microwaves, methods. The EO had a refractive index of 1.483 ± 0.001 (20 °C) and a density of 0.873 ± 0.005 g/mL (27 °C). Color parameters of the oil corroborate the yellow hue observed by the naked eye. The Gas chromatography-Mass spectrometry (GC-MS), Fourier Transform Infrared (FT-IR) Spectrometry, and Nuclear Magnetic Resonance (NMR) techniques permitted to characterize the EO and revealed the chemical structure of the major component: citral (neral and geranial). The phenolic compounds content was 149.2 ± 6.0 mg Gallic acid equivalents (GAE) per 100 mL of oil and the antioxidant activity was 44.06 ± 0.20 mg Trolox (T) per 100 mL of essential oil.</p>

“…Disamping itu, suhu uap pada metode SHD lebih merata, rendemen lebih besar, kualitas lebih baik dan waktu penyulingan yang lebih singkat dibandingkan metode HD [6]. Hingga saat ini, metode SHD masih lebih popular di kalangan penyuling tradisional skala kecil dibandingkan metode SD, dikarenakan rendemen SD hanya mencapai 0,7% dan membutuhkan biaya investasi yang cukup besar [7].…”

The Steam-Hydro Distillation (SHD) is a common method in the citronella oil processing industry. However, the yield and quality of the oil produced tend to be inconsistent, and the energy consumption is quite high. Hence, the process intensification in the distillation of citronella oil using ultrasonic waves is expected to increase the yield and quality of the oil produced, as well as a reduction in energy requirements. This research was conducted to examine the effect of operating conditions of sonication on the Ultrasonic following Steam-Hydro Distillation (US-SHD) on the yield and quality of citronella oil. The extraction of citronella oil with the US-SHD was carried out through the sonication stage for 5, 10, 15 and 20 minutes and used a power of 180 and 360 watts. This process then followed by the distillation stage for 60 minutes. In the US-SHD, the highest yield of citronella oil obtained by sonication for 20 minutes with 360 watts of power was 1,13%. Whereas in the SHD, the yield obtained was only 0,85%. The results of this study also showed that with a slight increase in energy consumption due to ultrasonic wave induction (13,92%), it was able to produce a substantial increase in citronella oil yield (31,83%), but did not significantly influence its density.

“…Peak at 1229.92 cm -1 and 1108.75 cm -1 represent C-O stretch of alcohol and few peak observed at wavelength around 888.02 cm -1 , 824.53 cm -1 and 721.35 cm -1 for alkenyl C-H bending. Since this study used Java CO from Cymbopogon winterianus, which is rich in monoterpene alcohol such as citronellal, geraniol and citronellol [10], therefore alchohol and alkanes peak appearance in FT-IR spectra proven the characteristic of CO. Gel-B spectra showed strong broad peak at 3309.73 cm -1 which represent normal polymeric O-H stretching and N-H stretching of amines and amides. Besides, Gel-B spectra also showed a broad weak peak at 1737.90 cm -1 represent C-O stretching of ester and a broad medium peak at 1635.37 cm -1 indicating N-H bending of amines and C-O stretching of amides respectively.…”

“…There was also a study done by [8] which utilized CO in formulation of mosquito repellent waterbased paint. It was suggested by [9] and [10] that CO demonstrates good efficacy against mosquitoes in concentrations ranging from 0.05% to 15% (w/v) alone or in combination with other natural or commercial insect repellent products. Although synthetic chemical N,Ndiethyl-3-methylbenzamide (DEET) is currently the most effective mosquito repellent, but due to adverse effects reported such include skin eruption in children and irreversible damage to the ecosystem from nondegradable compound in DEET, development of effective non-DEET alternatives is needed [7].…”

Abstract. Citronella oil (CO) can be an effective mosquito repellent, but due to its nature which having high volatility, oils rapidly evaporates causing loss of efficacy and shorten the repellent effect. Therefore, microencapsulation technology was implemented to ensure the encapsulated material being protected from immediate contact with environment and offers controlled release. In this study, microencapsulation of CO was done by employing complex coacervation using chitosan-gelatin (B) system and utilized proanthocyanidins as the crosslinker. Remarkably, nearly all material involved in this study are from natural sources which are safe to human and environment. In designing operating process condition for CO encapsulation process, we found that wall ratio of 1:35 and pH 5 was the best operating condition based on zeta potential and turbidity analysis. FT-IR analysis found that gelatin-B had coated the CO droplet during emulsification stage, chitosan started to interact with gelatin-B to form a polyelectrolyte complex in adjust pH stage, CO capsules solidified at cooling process and were hardened during crosslinking process. Final product of CO capsules after settling process was identified at the top layer. Surface morphology of CO capsules obtained in this study were described having diameter varies from 81.63 Pm to 156.74 Pm with almost spherical in shape.
