Three new abietane-type diterpenoids, named callicapoic acid M3 (1), callicapoic acid M4 (2) and callicapoic acid M5 (3), were isolated from the Callicarpa macrophylla Vahl. Their structures were established by spectroscopic techniques (IR, UV, MS, 1D and 2D NMR). All the isolated three compounds were evaluated for inhibitory activity on NO production in LPS-activated RAW 264.7 macrophage cells...
Four aporphine alkaloids from the wood of Ocotea macrophylla (Lauraceae) were isolated and characterized as (S)-3-methoxynordomesticine (1), (S)-N-ethoxycarbonyl-3-methoxy-nordomesticine (2), (S)-N-formyl-3-methoxy-nordomesticine (3) and (S)N-methoxycarbonyl-3-methoxy-nordomesticine (4); alkaloids 2-4 are being report for the first time. The structure the isolated compounds were determined base...
The phytochemical investigation on 1 g of materials from Gypsoplacamacrophylla (Zahlbr.) Timdal resulted in the discovery of gypmacrophin A, a rare pentacyclic sesterterpenoid; brialmontin III, a new polysubstituted depside and two known ones, brialmontins I and II. The structure and absolute configurations of gypmacrophin A were elucidated by spectroscopic analyses and computational methods. G...
زمینه و هدف: عصاره ریشه سنبل الطیب در درمان اختلالات خواب، استرس، افسردگی، اضطراب، سفتی عضلات و تشنج استفاده می شود.آستروسیت ها نقش تغذیه، حفاظت و حمایت از نورون ها دارند. هدف از این مطالعه، بررسی اثرات عصاره هیدروالکلی سنبل الطیب بر تعداد و اندازه آستروسیت های هسته رافه ماگنوس موش صحرایی بود. روش بررسی: در این مطالعه تجربی 40 سر موش صحرایی نژاد ویستار با وزن 250ـ170 گرم به طور تصادفی به سه گرو...
Xylem maturation depends on cambial age rather than diameter growth in Shorea macrophylla by the model selections for radial variations cell length, wood fiber traits, and basic density. Radial anatomical characteristics properties were investigated 23-year-old (engkabang) trees planted Sarawak, Malaysia. The effects of rates manner xylem determined based selected mixed-effects models. best mod...
Hydrangeae Dulcis Folium, the fermented and dried leaves of Hydrangea macrophylla SER. var. thunbergii MAKINO, suppressed D-galactosamine-induced liver injury by 85.2% when added to the diet at 1% and fed to rats for fifteen days. The hepatoprotective effect is more potent than that of a milk thistle extract and turmeric powder. Some fractionated extracts showed hepatoprotective activity in the...
While microsatellites have been used to examine genetic structure in local populations of Neotropical trees, genetic studies based on such high-resolution markers have not been carried out for Mesoamerica as a whole. Here we assess the genetic structure of the Mesoamerican mahogany Swietenia macrophylla King (big-leaf mahogany), a Neotropical tree species recently listed as endangered in CITES ...
