Our interest is to identify compounds from the patchouli oil of Pogostemon herba to inhibit the cyclooxygenase-1 (COX-1) enzyme activity. The data for the major compounds (alpha-patchouli alcohol isomer (CD521903, CD442384, and/or CD6432585), alphabulnusene, seychellene and alpha-guaiene) of
The constituents of the volatile oil of Pogostemon cablin collected from Wanning city, Hainan province and the influence owing to different collection time were undertaken by GC/MS combination technology. The results showed that main compounds was patchouli alcohol in stem oil and leaf oil, its
OBJECTIVE
The aim of this study was to evaluate the effect of Pogostemon cablin essential oil (PEO) on leukocyte behavior in the inflammatory response.
RESULTS
PEO was analyzed using Gas Chromatography/Mass Spectrometry (GC/SM) and Nuclear Magnetic Resonance Spectroscopy (NMR) methods and showed
The aim of this research was to evaluate contact toxicity and repellency of the essential oil of Pogostemon cablin (Blanco) Bentham leaves against German cockroaches (Blattella germanica) (L.) and to isolate any active constituents. Essential oil of P. cablin leaves was obtained by hydrodistillation
Patchouli essential oil can be obtained from fresh, dried and fermented plant material. It is a highly valuable product in the fragrance industry and its quality changes depending upon raw material age and oil storage. In this work, patchouli essential oils derived from different treatments have
Patchouli is used as an incense material and essential oil. The characteristic odor of patchouli leaves results from the drying process used in their production; however, there have to date been no reports on the changes in the odor of patchouli leaves during the drying process. We investigated the
Pogostemon cablin, originating in Malaysia and India, is cultivated in southern China including Guangdong and Hainan Province, which was called GuangHuoXiang to differentiate it from the HuoXiang of the north, the species Agastache rugosa, that it resembles. Essential oil of P. cablin mainly
Valeriana jatamansi Jones germplasm collected from sub-temperate Himalayan region of Uttarakhand and North-East state of Meghalaya, India was evaluated under identical conditions at National Bureau of Plant Genetic Resources, Bhowali, India, to study germplasm diversity based on essential oil
To explore the diversity in the essential oil yield and composition of Valeriana jatamansi Jones (syn. V. wallichii DC) growing wild in Uttarakhand (Western Himalaya), 17 populations were collected from different locations and grown under similar conditions. Comparative results showed considerable
BACKGROUND
The phenolic content, volatile compound fingerprint and antioxidant capacity of Waldheimia glabra (Decne.) Regel (Asteraceae), a wild plant from the Himalayan mountains used in Sherpa religious rituals and in traditional medicine, were determined for the first time to investigate its
Pogostemon cablin Benth. (patchouli) is an important herb which possesses many therapeutic properties and is widely used in the fragrance industries. In traditional medicinal practices, it is used to treat colds, headaches, fever, nausea, vomiting, diarrhea, abdominal pain, insect and snake bites.
The chemical constituents of the volatile oil of the stems and leaves of Pogostemon cablin collected from Leizhou county have been analysed by means of GC-MS. The main constituents are patchouli alcohol, delta-guaiene, alpha-guaiene, seychellene, alpha-patchoulene, aciphyllene, trans-caryophyllene.
The chemical constituents of the volatile oil of the stems and leaves of Pogostemon cablin collected from Gaoyao county, Guangdong province, have been studied by means of GC-MS. Sixty four compounds have been identified. The main constituents are pogostone (30.99% in stems, 21.31% in leaves, the
