A new unusual kauranoid diterpene glycoside, named amygdaloside, was isolated from the nuts of almond (Prunus amygdalus). It’s structure was established as 17-O-D-glucopyranoside ent-6,7-epoxy-6-hydroxyl-6,7-secokaur-19-oic acid, 6,19lactone 16 17-diol on the basis of high-resolution 1D and 2D NMR spectral studies. © 2003 Elsevier Science Ltd.

INTRODUCTION Over a period of time researchers have become more interested in finding out the potential of various foods to maintain the general health and to treat diseases. Almonds are a very good source of many nutrients which may help to sharpen the memory and to reduce cardiovascular risk factors. OBJECTIVE The present study was conducted to evaluate the nootropic effects of almonds. Eff...
Despite senescence-induced chlorophyll depletion in plants has been widely studied, the enzymatic background of this physiologically regulated process still remains highly unclear. The purpose of this study was to determine selected biochemical properties of partially purified fractions of chlorophyllase (Chlase, chlorophyll chlorophyllido-hydrolase, EC 3.1.1.14) from leaves of three Prunus spe...
بادام کوهی (amygdalus scoparia l) یکی از گونه های مهم خانواده روزاسه (rosaceae) است که از خواص دارویی و آنتی اکسیدانی ویژه ای برخوردار است.جنس amygdalus از نظر صفات ریخت شناختی از تنوع زیادی برخوردار است؛ به گونه ای که با اتکا به این صفات، در موارد بسیاری، قادر به شناسایی گونه ها نخواهیم بود. با توجه به اهمیت شناخت مراحل تکوینی گیاهان در گسترش دانش زیست شناسی، در این پژوهش، بادام کوهیکه از ارزش...
In the course of chemotaxonomic study of the genus Prunus, seven flavonol glycosides were isolated from the leaves of Prunus serotina Ehrh., characterized by UV and NMR spectroscopy, and identified finally as three quercetin monosides: hyperoside, avicularin, reynoutrin, three quercetin biosides: 3-O-(6"-O-alpha-L-rhamnopyranosyl)-beta-D-glucopyranoside, 3-O-(2"-O-alpha-L-rhamnopyranosyl)-beta-...
