Temporal aspects of the fine-scale genetic structure in a population of Cinnamomum insularimontanum (Lauraceae). (1/15)Cinnamomum insularimontanum Hayata (Lauraceae) is an insect-pollinated, broad-leaved evergreen tree with bird-dispersed seeds. We used allozyme loci, Wright's fixation index, spatial autocorrelation statistics (Moran's I), and coancestry measures to examine changes in genetic structure among four age-classes within a recently founded study population (60 x 100 m area) in southern Korea. There were no significant differences in expected heterozygosity among age classes. However, significant genetic differentiation among age classes was detected (P<0.0001). Fixation indices within age classes showed significant deficits of observed heterozygosity, which may be caused by partial selfing. The homogeneity of genetic structure among four age-classes may reflect similar spatial patterns of seed immigration from surrounding populations occurring year after year. Finally, the average Moran's I and coancestry estimates indicated essentially random spatial distributions of alleles for each of the four age-classes and between seedlings and 2-4 year juveniles vs adult trees. These findings are very similar to those observed in the same study area for another member of the Lauraceae, Neolitsea sericea, which has a very similar life history and ecological characteristics (ie, bird-dispersed fruits, insect pollination, and a similar age structure). Together, these results suggest that the fleshy drupes of lauraceous species represent an adaptation to aid in the independent dispersal of seed by birds, which in turn may increase the genetic diversity of founders colonizing new habitats.

Microwave-assisted isolation of essential oil of Cinnamomum iners Reinw. ex Bl.: comparison with conventional hydrodistillation. (2/15)Microwave-assisted hydrodistillation was used to isolate an essential oil from the leaves of Cinnamomum iners Reinw. ex Bl., and the results compared with those obtained by conventional hydrodistillation. The composition of the oil from both methods was found to be similar, and (-)-linalool was found as the main component (30-50%). The antioxidant activity of the essential oil obtained by both methods was evaluated using DPPH, ABTS, FRAP and lipid peroxidation methods, all of which indicated the same but insignificant activity.

Cytotoxic constituents from the leaves of Cinnamomum subavenium. (3/15)Two new butanolides, subamolide D (1) and subamolide E (2), and a new secobutanolide, secosubamolide A (3), along with 21 known compounds were isolated from the leaves of Cinnamomum subavenium. The structures of 1-3 were determined by spectroscopic analysis. Propidium iodide staining and cytometry analysis were used to evaluate the cell cycle progression of the treated SW480 cells and it was found that 1 and 2 caused DNA damage in a dose- and time-dependent manner.

Acrolein is a colorless gas with a pungent, irritating odor. It is a highly reactive compound that is produced naturally in the environment and is also formed during the incomplete combustion of organic materials, such as tobacco smoke and wood fires. In the medical field, acrolein is known to be a toxic substance that can cause a range of adverse health effects, including irritation of the eyes, nose, and throat, as well as damage to the lungs, kidneys, and other organs. It has also been linked to the development of certain types of cancer, including lung cancer and bladder cancer. In addition, acrolein has been shown to have anti-inflammatory and anti-viral properties, and it is being studied for its potential use in the treatment of certain medical conditions.
In the medical field, "Oils, Volatile" refers to a group of liquid hydrocarbons that have a low boiling point and evaporate easily at room temperature. These oils are typically derived from plants and are used for a variety of purposes, including as fragrances, solvents, and medicinal agents. Volatile oils are composed of a complex mixture of chemical compounds, including terpenes, aldehydes, ketones, and esters. They are known for their strong aroma and are often used in perfumes, cosmetics, and aromatherapy. In the medical field, volatile oils have been used for centuries for their medicinal properties. They are believed to have anti-inflammatory, analgesic, and antimicrobial effects, and are used to treat a variety of conditions, including respiratory infections, digestive disorders, and skin conditions. Some examples of volatile oils used in medicine include eucalyptus oil, peppermint oil, tea tree oil, and lavender oil. However, it is important to note that the use of volatile oils should be done under the guidance of a healthcare professional, as they can be toxic in high concentrations and may cause skin irritation or other adverse reactions.
Eugenol is a natural compound that is extracted from the essential oils of various plants, including cloves, cinnamon, and basil. It has been used in traditional medicine for centuries and has a wide range of potential therapeutic effects. In the medical field, eugenol is used as a local anesthetic and analgesic, meaning it can numb the pain and reduce inflammation in the affected area. It is also used as an antiseptic and antimicrobial agent to treat infections and prevent the growth of bacteria, viruses, and fungi. Eugenol has been studied for its potential use in treating a variety of medical conditions, including cancer, diabetes, and cardiovascular disease. It has been shown to have anti-inflammatory, antioxidant, and anti-cancer properties, and may help to reduce the risk of chronic diseases. However, more research is needed to fully understand the potential therapeutic effects of eugenol and to determine the appropriate dosage and safety of its use in medical treatments.
Plant extracts refer to the active compounds or bioactive molecules that are extracted from plants and used in the medical field for various therapeutic purposes. These extracts are obtained through various extraction methods, such as solvent extraction, steam distillation, and cold pressing, and can be used in the form of powders, liquids, or capsules. Plant extracts have been used for centuries in traditional medicine and are now widely used in modern medicine as well. They are used to treat a wide range of conditions, including inflammation, pain, anxiety, depression, and cancer. Some examples of plant extracts used in medicine include aspirin (extracted from willow bark), quinine (extracted from cinchona bark), and morphine (extracted from opium poppy). Plant extracts are also used in the development of new drugs and therapies. Researchers extract compounds from plants and test them for their potential therapeutic effects. If a compound shows promise, it can be further developed into a drug that can be used to treat a specific condition. It is important to note that while plant extracts can be effective in treating certain conditions, they can also have side effects and may interact with other medications. Therefore, it is important to consult with a healthcare professional before using plant extracts as a form of treatment.
