Cedrol is a sesquiterpene alcohol found in the essential oil of conifers (cedar oil), especially in the genera Cupressus (cypress) and Juniperus (juniper). It has also been identified in Origanum onites, a plant related to oregano. [3] Its main uses are in the chemistry of aroma compounds. [4] It makes up about 19% of cedarwood oil Texas and 15.8% of cedarwood oil Virginia. [5] Cedrol has not ...
In light microscopy, oil immersion is a technique used to increase the resolving power of a microscope. This is achieved by immersing both the objective lens and the specimen in a transparent oil of high refractive index, thereby increasing the numerical aperture of the objective lens. Without oil, light waves reflect off the slide specimen ...
The ancients made cedarwood oil from Lebanon cedar, a true cedar of the genus Cedrus, However, the species used for modern cedar chests and closets in North America is Juniperus virginiana, and cedarwood oil is now typically derived from various junipers and cypresses (of the family Cupressaceae).
Microscopy is the technical field of using microscopes to view objects and areas of objects that cannot be seen with the naked eye (objects that are not within the resolution range of the normal eye). [1] There are three well-known branches of microscopy: optical, electron, and scanning probe microscopy, along with the emerging field of X-ray microscopy. [citation needed] Optical microscopy ...
Oil of Thuja contains the terpene thujone which has been studied for its GABA receptor antagonizing effects, with potentially lethal properties. [26] Cedarwood oil and cedar leaf oil, which are derived from Thuja occidentalis, have different properties and uses.
The Raman microscope begins with a standard optical microscope, and adds an excitation laser, laser rejection filters, a spectrometer or monochromator, and an optical sensitive detector such as a charge-coupled device (CCD), or photomultiplier tube, (PMT). Traditionally Raman microscopy was used to measure the Raman spectrum of a point on a sample, more recently the technique has been extended ...
The outer bark and stem are astringent. [25] Because of its antifungal and insect repellent properties, rooms made of deodar cedar wood are used to store meat and food grains like oats and wheat in Shimla, Kullu, and Kinnaur district of Himachal Pradesh. Cedar oil is often used for its aromatic properties, especially in aromatherapy.
