Chemical composition of three extracts ofBursera graveolens

Abstract

Three different extracts were separated by diethyl ether extraction, simultaneous steam distillation extraction and roasted aroma extraction (dry distillation) from Bursera graveolens. It was possible to identify 100 compounds in the three different extracts by GC-MS. The odour-active compounds present in the extracts were evaluated by gas chromatography-olfactometry (GC-O). It was estimated that mono-or sesquiterpenoids contributed to woody, herbal and minty aromas of the woody material of B. graveolens. On the other hand, the roast aroma produced by burning chips included several aroma compounds, such as cyclotene and vanillin.

Influence of the chemical structure on the odor qualities and odor thresholds of guaiacol-derived odorants, Part 1: Alkylated, alkenylated and methoxylated derivatives

“…In the same study the odor of chavibetol was described as ''unusual" and exotic, but without any further specifications. In extracts of Bursera graveolens, and Angelica pubescens as well as Angelica sinensis, which are all used in traditional Chinese medicine, 5-methyl-and 4-vinylguaiacol have been identified in minor amounts amongst other compounds (Song, Deng, Wu, & Hu, 2004;Yukawa, Imayoshi, Iwabuchi, Komemushi, & Sawabe, 2006). Other derivatives, namely 4-methyl-, 4-ethyl-, 6-ethyl-, 4-propyl-and 4-allylguaiacol have been identified in two Japanese plant genera (Larix kaempferi and Sasa kurilensis) (Yasuhara & Sugiura, 1987).…”

Biodegradation of Residues from the Palo Santo (Bursera graveolens) Essential Oil Extraction and Their Potential for Enzyme Production Using Native Xylaria Fungi from Southern Ecuador

“…The Palo Santo is considered a vital resource for the local communities of the dry forest, as different parts of the tree are used in traditional medicine, as well as for the extraction of essential oil [3]. In addition, the wood and stalks are applied to prevent mosquito bites and to treat aches and pains of differing origins, such as fibrosarcoma, atherosclerosis, and arthritis [4].…”

“…The essential oil content of the different parts of B. graveolens is relatively high. The wood in the form of kindling contains up to 5.2% of essential oil and the shavings up to 3.4% [3]. Using the fruits, the distillation process is less efficient because the fresh fruits only contain up to 3% of essential oil.…”

Lactones 38: Synthesis and odoriferous properties of p‐menthane lactones

“…The best‐known mintlactones 1 , 2a–5a and 6 were isolated from the essential oils of several Mentha species . In 1997, Iwabuchi reported the isolation of enantiomeric (+)‐3‐hydroxymintlactone ( 2b ), (+)‐mintlactone ( 3b ), (−)‐isomintlactone ( 4b ) and (−)‐2,3‐didehydromintlactone ( 5b ) from the oils of woods Bursera graveolens . The synthesis of all the eight possible diastereoisomers of the completely saturated analogues of (−)‐mintlactone ( 3a ) and (+)‐isomintlactone ( 4a ) was reported by Gaudin .…”

“…[1][2][3][4][5][6][7] In 1997, Iwabuchi reported the isolation of enantiomeric (+)-3hydroxymintlactone (2b), (+)-mintlactone (3b), (À)-isomintlactone (4b) and (À)-2,3-didehydromintlactone (5b) from the oils of woods Bursera graveolens. [8][9][10] The synthesis of all the eight possible diastereoisomers of the completely saturated analogues of (À)-mintlactone (3a) and (+)-isomintlactone (4a) was reported by Gaudin. [11,12] This work allowed Näf to show the occurrence of three diastereoisomers, 7a-7c, in Mentha piperita L. essential oil.…”
