“…From C. reticulatum Hayata, nine new compounds have been isolated, including four from the leaves, i.e., 2-(4-hydroxy-3-methoxyphenyl)ethyl hexacosanoate ( 61 ), 2-(4-hydroxy-3-methoxyphenyl)ethyl octacosanoate ( 62 ) [ 38 ], isoreticulide ( 63 ) [ 39 ], and reticuol ( 64 ) [ 40 ], and five from the stem, i.e., reticuone ( 65 ) [ 41 ], a mixture of 4-hydroxy-3-methoxyphenethyl pentadecyrate ( 66 ), 4-hydroxy-3-methoxyphenethyl stearate ( 67 ), 4-hydroxy-3-methoxyphenethyl heneicosyrate ( 68 ) [ 42 ], and cinnaretamine ( 69 ) [ 43 ].…”

Taiwan is rich in lauraceous plants. A review of 197 references based on the chemical analysis and bioactivity of indigenous lauraceous plants carried out by native scientists from 1963 to 2014 has been compiled. About 303 new compounds and thousands of known compounds comprising alkaloids and non-alkaloids with diverse structures have been isolated or identified from indigenous plants belonging to the 11 lauraceous genera. The volatile components, however, have been excluded from this review. This review provides an overview of the past efforts of Taiwan scientists working on secondary metabolites and their bioactivity in native lauraceous plants. The potential of lauraceous plants worthy of further study is also noted. The contents will be helpful for the chemotaxonomy of Lauraceae and be of value for the development of native Formosan lauraceous plants.

“…Lauraceae family have furan butanolides, especially Cinnamomum plants. Butanolides were reported to be distributed in the genus Cinnamomum [23][24][25][26], Machilus [27], Persea [28], Lindera [19,29,30], Actinodaphne [31], Litsea [32], and Aiouea [33] before. Here, C. camphora has been proved to contain butanolides as well.…”

Three lignans (1–3) and three butanolides (4–6) were isolated from the lipophilic extract of the Cinnamomum camphora stem bark. The six compounds were identified as (-)-sesamin (1), 9α-hydroxysesamin (2), 9β-hydroxysesamin (3), obtusilactone A (4), isoobtusilactone A (IOA, 5), and isomahubanolide (6) from their spectroscopic data. Four (1, 2 and 5, 6) of them were evaluated for their repellent and feeding deterrent activities against Tribolium castaneum. In this work, the three butanolides (4–6) were confirmed to exist in C. camphora for the first time. Results of bioassays indicated that (-)-sesamin (1), IOA (5), and isomahubanolide (6) displayed certain repellent activities against T. castaneum at 78.63, 15.73, and 3.15 μg/cm2 at 2 h after exposure. Among the three compounds, (-)-sesamin (1) and IOA (5) exerted stronger effects and maintained longer duration of repellency. Furthermore, IOA (5) and isomahubanolide (6) showed good feeding deterrent activity against T. castaneum. IOA (5) was still potently active at low concentrations with the feeding deterrence index (FDI) ranging from 42.85% to 50.66% at 15–1500 ppm. This work provides some evidence for explaining antiinsect properties of the nonvolatile fraction of the C. camphora stem bark and helps promote the development and comprehensive utilization of this tree species.

“…The ethanolic extract of Pleurothyrium cinereum also contained (+)-demethylpiperitol ( 48 ), as well as (+)-de-4’’-O-methylmagnolin ( 49 ), which was found to be a potent COX-2/5-LOX dual inhibitor and platelet-activating factor (PAF)-antagonist (COX-2: IC 50 = 2.27 μM; 5-LOX: IC 50 = 5.05 μM; PAF: IC 50 = 2.51 μM) ( 49 ) [6,28]. (+)-Syringaresinol ( 50 ) was isolated from the stems of C. reticulatum Hay [29]. (+)-De-4’’-O-methylmagnolin ( 49 ) and (+)-syringaresinol ( 50 ) both were found to occur in the methanolic extract of the stems of Actinodaphne lancifolia [30].…”
