Essential oils are composed of some natural, volatile, as well as aromatic compounds extracted from plants. In recent years, several studies have shown that some of their benefits can be attributed to their antimicrobial, antioxidant, anti-inflammatory, and also immunomodulatory properties. So, essential oils have been proposed as a common elective to anti-microbials or for utilize in combination with other antimicrobials against multidrug-resistant microscopic organisms. Most of the potential data about essential oils were obtained with in vitro and in vivo studies. Several types of essential oils are available in Indonesia which are reported to have biological activity such as antioxidants and antiaging are essential oils of pine (Pinus merkusii), kilemo (Litsea cubeba), agarwood (Aquilaria spp), eucalyptus (Eucalyptus citriodora), and cinnamon (Cinnamomum burmanii). The major chemical compound of pine oil is alpha pinene. Kilemo oil contains geranial. chemical marker compound of agarwood is chromone and sesquiterpenes. Eucalyptus contains citronella. The chemical component of cinnamon oil is cinnamaldehyde. Some essential oils have shown remarkable antioxidant activities when used at specific concentrations which can be due to their richness in phenolic compounds. However, toxicological studies are needed before any recommendation for application can be given. Preformulating and formulation studies will be needed to develop suitable dosage forms in order to introduce optimized pharmaceuticals (high active, low toxic) as alternative of current pharmaceutical dosage forms

Background: Currently, there are at least 43 different dosage forms present on the Russian Federation pharmaceutical market. A novel, unique dosage form {\textendash} cut-pressed granules (CPG) {\textendash} was developed in order to improve manufacturing characteristics and, therefore, quality of herbal drug products released in tea bags. However, treatment conditions may result in decreased levels of active substances in some of the plants, especially those containing essential oil, which is prone to degradation. The aim of this study was to assess feasibility of CPG manufacturing from herbal raw material rich in essential oil. Materials and Methods: Different morphological groups of raw material from two commonly used medicinal plants, chamomile (Matricaria recutita L.) flowers and sweet flag (Acorus calamus L.) rhizome, were chosen as the objects of the study. Qualitative composition of lipophilic constituents in herbal raw materials and CPG was assessed using thin-layer chromatography. Essential oil content was determined by steam distillation. Results: The results confirmed equivalence of chromatographic profiles for the analyzed raw materials and CPG; thus, granulation didn{\textquoteright}t affect qualitative composition of lipophilic components in chamomile flowers and sweet flag rhizome. The study also showed that the granulation process, in fact, promoted stability of the dosage form: during long-term storage the content of essential oil in all of the assessed cut-pressed granules was equivalent or higher than in corresponding herbal raw material. Conclusions: It can be concluded that Matricaria recutita L. flowers and Acorus calamus L. rhizome can be used as herbal raw material for CPG manufacturing.

Eurycoma longifolia Jack (Tongkat Ali) roots are used in traditional medicines for its wide range of biological effects. The process of extracting out this essential oil from the plant requires a delicate and efficient method. In this research the extract of the essential oil of Eurycoma longifolia\’s root using Microwave Assisted Extraction (MAE), Soxhlet Extraction and Conventional Steam Extraction (CSE) methods, is characterized to identify the components of essential oil extracted and then to compare the yield percentage and components of the extracts from both methods. The extract obtained was characterized using gas chromatography mass spectroscopy (GC-MS) by comparing the compositions of components present in commercial Tongkat Ali oil stored in the GC-MS library. The findings showed that the MAE gives a maximum yield percentage of 5\% with six chemical components extracted in 20 min while SE and CSE gives high yield percentage of 28.3\% in 3 h and 2.5 \% in 6 h respectively with only three chemical components extracted. Therefore, MAE is the optimum method for extracting essential oil from Tongkat Ali with a high quality.

Introduction: There are not effective drugs available for treatment of dengue fever despite intensive research on synthetic inhibitors. The search for active phytochemicals could serve for the discovery of new drugs. This study aims to evaluate the antiviral activity in vitro of compounds found in essential oils from medicinal plants. Materials and Methods: Nine synthetic-derived essential oil compounds were evaluated. Antiviral effect was screened measuring the reduction of viral NS1 and E proteins in HepG-2 and Vero cells. Results: \β-Caryophyllene was identified as the most active compound, it reduced the virus serotype-2 replication in HepG-2 cells at IC50 of 22 \± 5.6 \μM, and blocked replication of all four serotypes in Vero cells at IC50 between 8.0 \μM and 15.0 \μM. The selectivity indexes were between 5.3 and 10. According to results from time-in-addition assays, the antiviral effect of \β-caryophyllene appears to be associated with interruption of early steps of the virus life cycle. Citral revealed modest antiviral effect, it reduced the virus serotype-2 (IC50 of 31 \± 4.5 \μM) replication but not the other three serotypes. Seven terpenes did not reveal antiviral activity at maximum concentration of 30 \μM. Conclusion: Research on compounds found in essential oils can contribute to the drug discovery effort for dengue. \β-Caryophyllene could serve as a starting point.

Introduction:Plectranthus amboinicus (Lour) Spreng is a known medicinal plant used in Siddha and Ayurveda medicines in India. It has enormous medicinal potential to treat various diseases. Methods: The present study focused on the use of essential oil obtained from the leaves of Plectranthus amboinicus to test cytotoxicity against breast (MCF-7) and colorectal (HT-29) cancer cell lines, to protect DNA from H2O2 induced genotoxicity through comet assay and to treat inflammation in lipopolysaccharide (LPS) induced over expression of matrix metalloproteinase-9 (MMP-9) in human peripheral blood mononuclear cells (PBMCs) by gelatin zymogram and inhibition at transcriptional level confirmed using RT-PCR (reverse transcriptase polymerase chain reaction). Results: Cytotoxicity of essential oil against MCF-7 and HT-29 cancer cell lines revealed the IC50 values of 53 \± 0.01 and 87 \± 0.01\μg/mL respectively. At 200 \μg/mL essential oil protected against 75\% of DNA damage in 3T3-L1 fibroblast cells. Essential oil showed significant reduction in production of MMP-9 in a concentration dependent manner. Conclusion: Overall, the results showed that essential oil of P. amboinicus is a potent bioactive substance and it could be used in herbal medicine preparations.

Introduction: We have carried out our study on the chemical composition; anti-glycation andradical scavenging activities of Origanum compactum, Rosmarinus officinalis and Pelargonium asperum essential oils (EO) that were harvested in the northeast of Morocco. These plants have been traditionally used in medicine as a chief ingredient of many polyherbal formulations for the treatment of several pathologies. Method: The phytochemical study was revealed by GC-MS. The protein glycation inhibitory activity of EO extracted from these plant tissues was evaluated in vitro using the model system of bovine serum albumin and methylglyoxal. The measure of DPPH\• radical reducing power was used to evaluate the antiradical activity. To test each fraction, we used the IC50 value previously obtained for the crude oils. Results: The phytochemical study of these essential oils showed that p-Thymol, Eucalyptol and Citronellal were respectively the major components in the three investigated EO of O.compactum, R. officinal is and P. asperum. More than 90\% of the total components were detected. The extracts and fractions with glycation inhibitory activity also showed antiradical activity when the DPPH\• radical reducing power was measured. Conclusion: The glycation inhibitory activity was correlated with the antiradical potency of the extracts. Thus, the positive glycation inhibitory and antiradical activities of these plants might suggest a possible role in targeting aging and diabetic complications.The presence of various bioactive compounds confirms the application of these plants for various diseases by traditional practitioners. However, isolation of individual phytochemical constituents may proceed to find a novel drug.
