Lab.Several substances are used for example 334-48-5 and 35346-20-4 which are their cas registry numbers., Nagaoka Perfum. Co., Osaka 541, Japan). Nippon Nogei Kagaku Kaishi, 57(7), 663-6 (Japanese) 1983. CODEN: NNKKAA. DOCUMENT TYPE: Journal CA Section: 62 (Essential Oils and Cosmetics) The constituents of essential oils from mesocarps, seeds, and leaves of title plants, Lauraceae, were examd. by chromatog. and spectral methods. Oil yields from mesocarps, seeds, and leaves were 0.75, 0.036, and 0.10 in (A) L. obtusiloba and 1.008, 0.008, and 0.212% in (B) P. trilobum, resp. The major components from the (A) mesocarps oil were a-humulene (I) [6753-98-6] (21.45), myrcene [123-35-3] (20.60), humulol [28446-26-6] (6.03), bornyl acetate (II) [76-49-3] (5.06), d-cadinene [483-76-1] (4.17), limonene (III) [138-86-3] (3.66), and a-cadinene [24406-05-1] (3.03), whereas the components from the (B) oil were trans-b-ocimene [3779-61-1] (34.88), III (17.96), caryophyllene (IV) [87-44-5] (16.76), g-muurolene (V) [30021-74-0] (6.40), and delobanone (VI) [35346-20-4] (3.29%). The major components from (A) seed oil were 5-dodecanolide [713-95-1] (15.29), lauric acid [143-07-7] (8.74), II (5.01), cis-4-dodecenoic acid [7089-43-2] (4.07), IV (3.45) I (3.39), and 11-dodecen-1-al (VII) [51148-68-6] (3.37), whereas those from (B) seed oil weredodecanoic acid [143-07-7] (23.08), Et dodecanoate [106-33-2] (17.06), 2-undecanone [112-12-9] (5.18), Et laurate [106-33-2] (4.93), and V (3.72%). The components from (A) leaf oil were IV (7.37), elemol [639-99-6] (5.01), b-eudesmol [473-15-4] (3.32), VII (3.28), and caryophyllene oxide [1139-30-6] (3.20), whereas those from (B) leaf oil were VI (23.47), o-cresol [95-48-7] (8.24), 6-methyl-5-hepten-2-one [110-93-0] (6.83), b-maaliene [489-29-2] (4.17), and bisabolene [495-62-5] (3.05%). .

Study on the constituents of steam-distilled volatile oil from the flower of Aglaia odorata Lour. Liu, Zhujin; Wu, Houming; Fu, Guixiang; Xu, Yongzhen; Ming, Yaolan; Li, Aifang (Shanghai Inst. Org. Chem., Acad.In this study， 38230-60-3 and 87-44-5 are also used. Sin., Shanghai, Peop. Rep. China). Youji Huaxue, (6), 431-6 (Chinese) 1983. CODEN: YCHHDX. ISSN: 0253-2786. DOCUMENT TYPE: Journal CA Section: 62 (Essential Oils and Cosmetics) Chem. constituents of volatile oil from the flower of A. odorata were reinvestigated. The volatile oil was subjected to steam distn. to give a distillate, which was sepd. into a sesquiterpene fraction (A) and an O-contg. sesquiterpene fraction (B) by the chromatog. method as described previously. Fractions A and B were analyzed by gas chromatog.-mass spectrometry. Fraction A contained a-cubebene [17699-14-8], copaene [3856-25-5], caryophyllene [87-44-5], bicycloelemene [32531-56-9], humulene [6753-98-6], b-santalene [20478-87-9], g-muurolene [483-74-9], a-muurolene [10208-80-7], b-bisabolene [495-61-4], calamenene [483-77-2] and calacorene [21391-99-1], and fraction B contained 6-methyl-5-hepten-2-one [110-93-0], 2-ethylhexanol [104-76-7], epi-cubebol [38230-60-3], cubebol [23445-02-5], benzyl acetate [140-11-4], caryophyllene epoxide [1139-30-6], benzyl alc. [100-51-6], humuladienone [24405-90-1], ledol [577-27-5], epi-cubenol [19912-67-5], humulene epoxide I [19888-33-6], humulene epoxide II [19888-34-7], T-cadinol [5937-11-1], humulol [24405-58-1], d-cadinol [36564-42-8], cadienenol [55708-40-2], caryophyllenol [38284-26-3], humulenol [19888-00-7] and Me jasmonate [1211-29-6]. The g-elemene [29873-99-2] content in the distillate was 0% compared to 17.6% for the abs. oil and the humulene content in the distillate was 49.8% compared to 31.0% for the abs. oil as detd. in previous studies. The increased humulene content at the expense of g-elemene appeared to be due to a Cope rearrangement accompanied by a proton-catalyzed hydration-dehydration rearrangement during the steam distn. .
