In total, 29 compounds from sweet wormwood (Artemisia annua L.) oil were identified using gas chromatography-mass spectrometry. The five active components were D-camphor, linalool, cineole, α-terpineol, and L(-)-borneol. The effectiveness of A. annua oil, as well as d-camphor, linalool, cineole, α-terpineol, and L(-)-borneol, as fumigants, contact insecticides, and repellents, were tested on th...

Purpose: To establish an efficient method to recycle natural borneol from Cinnamomum camphor chvar. Borneol oil residue. Methods: The fractions and raffinate of the oil residue of Cinnamomum camphor chvar. Borneol were obtained by fractional distillation, and analyzed by gas chromatography with flame ionization detector (GC-FID) and gas chromatographymass spectrometry (GC-MS). Natural borneol w...

Borneol, a bicyclic monoterpene, has been evaluated for antinociceptive and anti-inflammatory activities. Antinociceptive and anti-inflammatory activities were studied by measuring nociception by acetic acid, formalin, hot plate, and grip strength tests, while inflammation was prompted by carrageenan-induced peritonitis. The rotarod test was used to evaluate motor coordination. Borneol produced...

The aim of this research was to determine the chemical constituents and bioactivity of the essential oil derived from Alpinia galanga (L.) Willd. rhizomes against the cigarette beetle Lasioderma serricorne (F.) (Coleoptera Anobiidae) adults. The essential oil of A. galanga obtained by hydrodistillation was investigated by gas chromatography-mass spectrometry (GC-MS). The main components of the ...

Borneol is a traditional Chinese medicine that can promote drug absorption from the gastrointestinal tract and distribution to the brain. However, stomach irritation may occur when high doses of borneol are used. In the present work, gastrodin, the main bioactive ingredient of the traditional Chinese drug "Tianma" (Rhizoma Gastrodiae) was used as a model drug to explore reasonable application o...

Blumea balsamifera (Ai-na-xiang) is used as an important plant source of natural borneol, which is widely used in the pharmaceutical industry. The aim of this study was to establish the methods based on near infrared (NIR) spectroscopy for determining the geographical origin of B. balsamifera, as well as developing a method for the quantitative rapid analysis of the active pharmaceutical ingred...

Bingpian is a time-honored herb in traditional Chinese medicine (TCM). It is an almost pure chemical with a chemical composition of (+)-borneol and has been historically used as a topical analgesic for millennia. However, the clinical efficacy of topical borneol lacks stringent evidence-based clinical studies and verifiable scientific mechanism. We examined the analgesic efficacy of topical bor...

Borneol, known as a "guide" drug in traditional Chinese medicine, is widely used as a natural penetration enhancer in modern clinical applications. Despite a large number of experimental studies on borneol's penetration enhancing effect, the molecular basis of its action on bio-membranes is still unclear. We carried out a series of coarse-grained molecular dynamics simulations with the borneol ...

Borneol is a compound widely used in ophthalmic preparations in China. Little is known about its exact role in treating eye diseases. Here we report that transient receptor potential melastatin 8 (TRPM8) channel is a pharmacological target of borneol and mediates its therapeutic effect in the eyes. Ca2+ measurement and electrophysiological recordings revealed that borneol activated TRPM8 channe...
