Direct hyphenation of analytical-scale high-performance liquid chromatography, photo-diode array detection, mass spectrometry, solid-phase extraction and nuclear magnetic resonance spectroscopy (HPLC-PDA-MS-SPE-NMR) has been used for accelerated dereplication of crude extract of Haplophyllum acutifolium (syn. Haplophyllum perforatum). This technique allowed fast on-line identification of six qu...
اسانس گیاهان خشک شده در سایه haplophyllum acutifolium، salvia chloroleuca به دو روش1.تقطیر با آب 2. روش میکرواستخراج فاز جامد با نمونه برداری از فضای فوقانی گرفته شد و سپس به روشgc/ms مورد آنالیز و شناسایی قرار گرفت. عمده ترکیبات اسانس گیاه haplophyllum acutifolium: stem oil (%) flower oil (%) leaf oil (%) ri compound with head space area %)) ri compound with hydrodistillation 19.19 17.55 3...
Two new lignan glycosides of dibenzylbutyrolactol type (haplomarin) and arylnaphthalene type (haploborin) were isolated from the aerial parts of Haplophyllumn suaveolens together with the known arylnaphthalene lignan glycoside arabelline and hydroxycoumarin glycoside xeroboside. So far arabelline is found only in H. buxbaunii. This is the first report of the isolation of xeroboside from Haploph...
مقدمه: به تأخیر انداختن جذب گلوکز از طریق مهار آنزیمهای تجزیهکنندهی کربوهیدراتها، یک روش درمانی برای کاهش هیپرگلیسمی پس از صرف غذا است. آلفاگلوکزیداز باعث تسریع آزاد شدن آلفاگلوکز از کربوهیدراتها میشود. گیاهان منابعی غنی از ترکیبات فعال زیستی هستند، امروزه تحقیقات بسیاری بر روی عصارههای گیاهی با هدف یافتن مهارکنندههای جدیدی برای این آنزیم در حال انجام است. هدف: یافتن مهارکنندههای قوی، ...
The volatile components of the aerial parts of Ruta graveolens and Haplophyllum suaveolens, as well as of leaves of Zanthoxylum limoncello, Z. panamense and Z. setulosum have been studied by GC/MS analysis.
objective: alpha-glucosidase, as a carbohydratase catalyses the liberation of alpha-glucose from the nonreducing end of some carbohydrates from foods in digestive tract. consequently, retard absorption of glucose by the inhibition of carbohydrate hydrolyzing enzymes is one of the therapeutic approaches to decrease the postprandial hyperglycemia. recently, a great deal of attention has been pai...

This study aimed to evaluate the in vitro and in vivo leishmanicidal activity of an endemic Turkish plant and compare its efficacy with a reference drug. In addition to the in vitro activities of the ethanol, acidified and alkaloid extracts and furoquinoline alkaloids skimmianine and gamma-fagarine, in vivo antileishmanial activitiy of the acidified extract of Haplophyllum myrtifolium Boiss. (R...
Insight derived from a synthetic model, calculated (13)C NMR data, and comparison to experimental data indicate that the proposed allenic structure A, originally assigned to an isolate from Brosimum acutifolium Huber, should be revised to B, a natural product and nonallenic substance, mururin C.
