Accurate knowledge of individual tree ages is critical for forestry and ecological research. However, previous methods suffer from flaws such as damage, low efficiency, or ignoring autocorrelation among residuals. In this paper, an approach estimating the trees proposed based on diameter series Cinnamomum camphora (Cinnamomum (L.) Presl), Schima superba (Schima Gardn. et Champ.), Liquidambar fo...

Objective(s): Nowadays, cardiovascular diseases (CVDs) are the major risk factors of death globally. One of the most undeniable reasons of CVDs is metabolic syndrome (MetS). MetS is defined as a complex of diseases including insulin resistance, hyperglycemia, obesity, high blood pressure and dyslipidemia. The use of complementary medicine such as traditional herbal species can be effective in t...

Ethnographic accounts suggest that emotions are moderated in Chinese cultures and expressed openly in Mexican cultures. The authors tested this notion by comparing subjective, behavioral, and physiological aspects of emotional responses to 3 (warned, unwarned, instructed to inhibit responding) aversive acoustic startle stimuli in 95 Chinese Americans and 64 Mexican Americans. Subjective reports...

In order to gain insight into the antioxidant effect of cinnamon (Cinnamomum verum; Lauraceae) and cardamom (Amomum subulatum; Zingiberaceae) hepatic and cardiac antioxidant enzymes, glutathione (GSH) content and lipid conjugated dienes were studied in rats fed high fat diet along with cinnamon or cardamom. The antioxidant enzyme activities were found to be significantly enhanced whereas GSH co...

Four new phenolic glycosides, including two flavonoid glycosides (1 and 2) and two lignan glycosides (3 and 4), were isolated from the traditional Chinese medicine formula, Baoyuan decoction. Their structures were established by detailed analysis of the NMR and HR-ESI-MS spectroscopic data and their absolute configurations were determined by the experimental electronic circular dichroism data a...

Cinnamaldehyde, of the genius Cinnamomum, is a major constituent of the bark of the cinnamon tree and possesses broad-spectrum antimicrobial activity. In this study, we used best multiple linear regression (BMLR) to develop quantitative structure activity relationship (QSAR) models for cinnamaldehyde derivatives against wood-decaying fungi Trametes versicolor and Gloeophyllun trabeum. Based on ...

Alcoholic extracts of the rhizomes of Alpinia galanga, Andrographis paniculata, bark of Cinnamomum zeylanicum, rind of Citrus decumana, Desmodium triflorum, seeds of Hydnocarpus wightiana, rhizomes of Kaempfaria galanga, Lippia nodiflora, tender leaves of Morinda citrifolia, rhizomes of Pollia serzogonian, Tephrosia purpuria and rhizomes of Zingiber zerumbeth showed good in vitro anthelmintic a...

Cinnamon, which is the bark of the Cinnamomum zeylanicum tree, contains cinnamic aldehyde, which is an irritant. Workers processing cinnamon before export are exposed to much cinnamon dust. Forty such workers with an average of four years' service in the industry were examined. Thirty five workers (87.5%) had symptoms, nine having had asthma (22.5%). Other symptoms, probably related to the irri...

The acceptance of camphor tree (Cinnamomum camphora) as a host plant for the larvae of common bluebottle (Graphium sarpedon nipponum) was explained by the presence of feeding stimulants in the leaves. When the active methanol extract of C. camphora leaves was separated into hexane and water layers, both layers showed high feeding activities for the larvae of G. sarpedon nipponum. Bioassay-guide...

The genus Cinnamomum of the family Lauraceae is an economically important crop. Ceylon cinnamon (Cinnamomum verum syn. C. zeylanicum) has exceptional position in global market. In addition to cultivated species, Sri Lanka home seven endemic wild capparu-coronde, citriodorum, dubium, litseifolium, ovalifolium, rivulorum, and sinharajaense. Nevertheless, species delimitation not been successful w...
