Comparative chemical analysis of the essential oil constituents in the bark, heartwood and fruits of Cryptocarya massoy (Oken) Kosterm. (Lauraceae) from Papua New Guinea. (1/6)Exhaustive hydro-distillation of the bark, heartwood and fruits of Cryptocarya massoy (Lauraceae) afforded pale yellow-coloured oils in 0.7, 1.2 and 1.0 % yields, respectively. Detailed chemical evaluation of these distillates using GC/MS revealed the major components in the bark and the heartwood oils to be the C-10 (5,6-dihydro-6-pentyl-2H-pyran-2-one) and C-12 (5,6-dihydro-6-heptyl-2H-pyran-2-one) massoia lactones, while the major fruit oil constituent was benzyl benzoate (68.3 %). The heartwood also contained trace amounts of the C-14 (5,6-dihydro-6-nonyl-2H-pyran-2-one) massoia lactone (1.4 %) and the saturated C-10 derivative delta-decalactone (2.5 %). (+info)
Cytotoxic and anti-HIV phenanthroindolizidine alkaloids from Cryptocarya chinensis. (2/6)Bioassay-guided fractionation of the cytotoxic ethanol extract of Cryptocarya chinensis has led to the isolation of 11 compounds, including two phenanthroindolizidine alkaloids [(-)-antofine (1) and dehydroantofine (2)], five pavine alkaloids (3-7), and four proaporphine alkaloids (8-11). The structures of the isolated compounds were determined by means of NMR spectroscopic methods, and supported by HRMS and optical rotation data. Compounds 1 and 2 showed cytotoxic activity against four cancer cell lines, L1210, P388, A549, and HCT-8, with 1 being the most potent against A549 and HCT-8 with EC50 values of 0.002 and 0.001 microg/mL, respectively. In addition, 2 is first reported to exhibit significant anti-HIV activity. (+info)

In the medical field, Cryptocarya is a genus of evergreen trees and shrubs that are native to Australia, New Zealand, and Southeast Asia. The leaves of Cryptocarya species are commonly used in traditional medicine to treat a variety of conditions, including respiratory infections, digestive disorders, and skin conditions. Some species of Cryptocarya are also used in the production of essential oils, which have been found to have antimicrobial, anti-inflammatory, and analgesic properties. However, it is important to note that the use of Cryptocarya in medicine is not well-established and more research is needed to fully understand its potential therapeutic effects and potential side effects.
