Dry wood appears to age differently. A study of a variety of species ranging in age from less than 1 year to 3700 years showed that there may be a decrease in hygroscopicity with age, but that the effect is small if it exists at all (18). Hinoki Chamaecyparis obtusa) taken from a 1300-year-old temple did, however, exhibit much lower equilibrium moisture content (EMC) values than recent wood (19). 

Two carbamates isolated from the bark of Chamaecyparis obtusa (Cu-pressaceae) have been named obtucarbamate A (150) and its isomer obtu-carbamate B (151) their structures were elucidated by spectroscopic and chemical methods (117). Two new peptide alkaloids have been isolated from the flowers of Hibiscus rosasinensis (Malvaceae), and their structures were characterized as 152 and 153 (118).

The natural product (+) -chamaecypanone C (223) was first isolated in 2007 by Kuo and coworkers [89] from the heartwood of Chamaecyparis obtusa var. Jbrmosana and shows strong anticancer potency. An enantioselective synthesis of this compound was described by Porco et al. in 2009 ]90] using a retro-Diels-Alder/Diels-Alder reaction as key step (Scheme 14.34).

The EO of Chamaecyparis obtusa (Siebold and Zucc.) Endl. (Cupressaceae) showed promising decrease of the production of LPS-induced PGE-2 and peripheral blood mononuclear cells. The expression of TNF-a and COX-2 was also inhibited. These results showed promising antiin ammatory activity (An et al., 2013).
