“…The reason why teak is loved by consumers is inseparable from its attractive appearance, and the unique color, which is highly correlative with the extractives. At present, the research on the chemical composition of teak is mostly around lignin, cellulose, and hemicelluloses [17]. Few studies are related to wood extractives, let alone to the extractives of teak in China [3,18,19,20,21].…”

In order to clarify the chemical color change of teak (Tectona grandis L.F.), the difference of chemical composition between the heartwood and sapwood of teak was investigated by gas chromatography–mass spectrometry (GC-MS) based on the acetone extractive compounds. The results showed that the difference in content of the main components between heartwood and sapwood was not obvious. However, the amount of extractives in heartwood was higher than that in sapwood, especially for phenols, quinones, and ketones. The most obvious different substances in the acetone extractive between heartwood and sapwood were 4-tert-butyl-2-phenyl-phenol,2-methyl-anthraquinone, and 2,3-dimethyl-1,4,4a,9a-tetrahydro-9,10-anthracenedione, which might be the main composition for the chromatic aberration of teak. This paper focuses on a preliminary study and further work such as high-performance liquid chromatography (HPLC) with ultraviolet photometric detector (UV)/mass spectrometry (MS) will be carried out.

“…According to Schollean et al [4], cellulose δ 18 O of teak collected from Java shows positive correlation with precipitation during the dry season before the growing season and shows negative correlation with precipitation during the rainy season. Moreover, Hisamochi et al [6] measured cellulose δ 18 O of ten teak disks collected at four sites in Java, and verified the synchronicity of the annual time-series variations. These results of earlier studies suggest that tree-ring cellulose δ 18 O is a reliable proxy for hydroclimate (i.e., precipitation and relative humidity) over Java Island.…”

“…The expressed population signal (EPS) was 0.93 during 1960-1998. The cellulose δ 18 O time series of teak has high spatial coherence over Java [6]. For this study, we referred to the average tree-ring cellulose δ 18 O of ten individual teak trees as measured values (Figure 1c).…”

“…In Indonesia, dendroclimatological studies have been conducted using tree-ring widths of teak (Tectona grandis) on Java Island [1][2][3][4]. Moreover, a few reports have described oxygen isotopic composition (δ 18 O) of tree-ring cellulose in Java [4][5][6]. According to Schollean et al [4], cellulose δ 18 O of teak collected from Java shows positive correlation with precipitation during the dry season before the growing season and shows negative correlation with precipitation during the rainy season.…”

Tree-ring cellulose oxygen isotopic composition (δ18O) is controlled by several hydrological factors such as precipitation, relative humidity, and temperature. A proxy system model can reveal how these factors affect tree-ring cellulose δ18O. In this study, to identify a key control on tree-ring cellulose δ18O variations, we performed model calculation of year-to year variation of tree-ring cellulose δ18O of Javanese teak in Indonesia from 1960 to 1998. Our model results reasonably reproduce the observed δ18O values and their temporal variations (r = 0.6; p < 0.001). Moreover, the sensitivity test shows that the cellulose δ18O values are sensitive to the teak growing period. The simulation result with earlier or later shifts of the growing period captured the amplitude of observed δ18O variations over 39 years. These results indicate that the tree-ring cellulose δ18O of Javanese teak might be influenced by a subtle shift of the intra-annual growing period.
