The UHPLC-QToF-MS analysis of pyrrolizidine alkaloids (PAs) from various parts of 37 botanicals and 7 products was performed. A separation by LC was achieved using a reversed-phase column and a gradient of water/acetonitrile each containing formic acid as the mobile phase. MS-MS detection was used because of its high selectivity, and ability to provide structural information. Free base and N-ox...
Somatostatin (SS) and dopamine (DA) receptors have been highlighted as two critical regulators in the negative control of hormonal secretion in a wide group of human endocrine tumors. Both families of receptors belong to the superfamily of G protein-coupled receptors and share a number of structural and functional characteristics. Because of the generally reported high expression of somatostati...
Diagnosis of cardiac sarcoidosis is often challenging. Whereas cardiac magnetic resonance imaging (CMR) and positron emission tomography/computed tomography (PET/CT) with 18F-fluorodeoxyglucose (FDG) are most commonly used to evaluate patients, PET/CT using radiolabeled somatostatin receptor (SSTR) ligands for visualization of inflammation might represent a more specific alternative. This study...
Various plant seeds have received little attention in fatty acid research. Seeds from 30 species mainly of Boraginaceae and Primulaceae were analysed in order to identify potential new sources of the n-3 PUFA α-linolenic acid (ALA) and stearidonic acid (SDA) and of the n-6 PUFA γ-linolenic acid (GLA). The fatty acid distribution differed enormously between genera of the same family. Echium spec...
During the preparation of the Vascular Flora of the Marquesas Islands a new endemic species of Heliotropium L. (Boraginaceae) has come to light and is described herein: Heliotropiumperlmanii Lorence & W. L. Wagner. It is known only from the island of Eiao and appears most closely related to Heliotropiummarchionicum Decne., also endemic to the Marquesas and known from Nuku Hiva. An amended descr...
The aerial parts of Coldenia procumbens Linn. (Boraginaceae) are used in indigenous systems of medicine. The market sample is in the form of small pieces or nearly powdered, from which the morphological and anatomical characters are unable to study for the identification and conformation of its authenticity. The present study of physicochemical characteristics like physical constant values, beh...
مقدمه: Heliotropium bacciferum یکی از گیاهان متعلق به تیره گاوزبان (Boraginaceae) میباشد که پراکندگی محدودی در جنوب ایران دارد. اثر آنتیباکتریال گونههای دیگرجنس Heliotropium گزارش شده است ولی گزارشی از این گونه وجود ندارد. هدف:هدف از این تحقیق ارزیابی اثر ضدمیکروبی گونه bacciferum علیه 5 سوش باکتریایی استافیلوکوکوس اورئوس (ATCC 6538)، باسیلوس سرئوس (ATCC 12826)، اشرشیاکلی (ATCC 8739)، سالمون...
