“…They were detected in leaves and inflorescences, whereas the core of the bulb in dormant status was devoid of these compounds. Nonesterified hydroxycinnamic acids as described in earlier studies [22] were not detected in sea squill in the present work.…”

Mediterranean sea squill (Drimia maritima (L.) Stearn) is used in the production of medicinal products. Current HPLC methods comprise tedious sample clean-up and have been merely focused on the analysis of cardiac glycosides, whereas a thorough characterization of D. maritima considering both the latter compound class and more hydrophilic secondary metabolites in one HPLC run has not been performed so far. Consequently, a novel HPLC-DAD-MS(n) method has been developed allowing the simultaneous determination of both cardiac glycosides and phenolic compounds, which is characterized by simplified sample preparation. This method was applied to characterize sea squill, revealing a complex profile of its extractive compounds derived from the two classes. Furthermore, the potential of the method reported here to quantitate the predominant compounds, i.e., dihydroquercetin derivatives and bufadienolides, was demonstrated. The occurrence of phenolic compounds, not described for sea squill so far, and of characteristic compounds specific to individual plant parts or vegetation stages was further addressed. The data revealed that classification of various vegetation phases based on quantitative evaluation of bufadienolides and dihydroquercetin derivatives applying principal component analysis (PCA) appears possible. Thus, the methodology presented here forms the basis for future routine application in quality control of raw materials and pharmaceutical preparations derived from sea squill. This will allow systematic comparison of different plant parts, vegetation stages and origins based on an extended sample set.

“…Cyanidin-glucosides acylated with caffeic acid or coumaric acid [13] as reported earlier were not detected in the present study. The same applies to anthocyanins like pelargonidin-glucoside and cyanidin-di-or triglucosides [13,22].…”

“…193,194 Red bulbs of C. maritima (as Urginia maritima), collected in the Balearic Islands contained cyanidin 495, cyanidin-3-monoglucoside 496 and pelargonidin-3-monoglucoside 497, both in the free form and acylated with p-coumaric acid. [212][213][214][215][216] The proportion of anthocyanin was found to be higher in tetraploids than in triploids or hexaploids. 217 The [220][221][222][223] Fernandez et al identied twenty-ve avonoids in a Spanish sample of C. maritima bulbs (as Urginia maritima).…”

The chemistry and biological activity of the Hyacinthaceae

The Hyacinthaceae (sensu APGII), with approximately 900 species in about 70 genera, can be divided into three main subfamilies, the Hyacinthoideae, the Urgineoideae and the Ornithogaloideae, with a small fourth subfamily the Oziroëoideae, restricted to South America. The plants included in this family have long been used in traditional medicine for a wide range of medicinal applications. This, together with some significant toxicity to livestock has led to the chemical composition of many of the species being investigated. The compounds found are, for the most part, subfamily-restricted, with homoisoflavanones and spirocyclic nortriterpenoids characterising the Hyacinthoideae, bufadienolides characterising the Urgineoideae, and cardenolides and steroidal glycosides characterising the Ornithogaloideae. The phytochemical profiles of 38 genera of the Hyacinthaceae will be discussed as well as any biological activity associated with both crude extracts and compounds isolated. The Hyacinthaceae of southern Africa were last reviewed in 2000 (T. S. Pohl, N. R. Crouch and D. A. Mulholland, Curr. Org. Chem., 2000, 4, 1287-1324; ref. 1); the current contribution considers the family at a global level.

“…From the phytochemical point of view, it has been reported that the major constituents of U. maritima bulbs are glycosides (cardiac glycosides) of the bufadienolide type (Kopp et al, 1996;Krenn et al, 2000;Iizuka et al, 2001). Anthocyanins (Vega et al, 1972), flavonoids (Fernandez et al, 1972), fatty acids, polysaccharides (Spies et al, 1992;Praznik and Spies, 1993) and calcium oxalate (Cogne et al, 2001) are also present.…”

The thanks I owe for this PhD are rather as many as the words that it consists of, probably equally important and definitely harder to express. I would, nevertheless, like to express my gratitude to everyone, who was, as meant to be, present or absent. I would like to express my deep gratitude to my supervisor Prof. Stylianos Delivopoulos for many things, most of which are difficult to express in words. I thank him for his continuous assistance, guidance, encouragement and friendship during the time I have spent at AUTH, Greece. Moreover, I would like to express my deep gratitude for his kindness and hospitality, for his quantity of enthusiasm and quality of interest. But most of all I thank him for having been both a teacher and a 'father' to me. I would also like to express my gratitude to Dr. Thomas Sawidis for helping me in the subject and scientifical revision of my work. I thank him for his kind heart which has boosted up my enthusiasm and emotions. I will never forget his assistance, discussions and joke especially about the "noble price". I also thank Dr. Barbara-Evelin Diannelidis for her endless assistance and encouragement. I am deeply grateful to the following botanical staff; Prof. Ioannes Tsekos who gave me the opportunity to elaborate my Ph.D at the Aristotle University of Thessaloniki before his retirement. In addition, I would like to express my very deep gratitude for his assistance and critical suggestions that he has made on my research. I also thank Dr. George Nikolaidis, Maria Moustaka and Michael Moustakas for their help and technical support especially in the use of their microscopes. Thanks are also due to Dr. Stylianos Kokkini, Artemios Bosabalidis and Eleftherios Eleftheriou for their moral support and encouragement. I am deep grateful to Dr Emmanuel-Nicholas Panderis for his friendship, jokes and some scientific assistance. Finally, I would like to thank everybody in the Department of Botany for the joyful atmosphere created in the lab during my research work. I also thank the SEM technician Mr. Stavros Oikonomidis for his help in carrying out the SEM protocol. I would like to express my deep gratitude to Mr. Tasos Makrantonakis and Thanasis Nikodimos for their help, moral support and lovely atmosphere created in Sharaf Al-Tardeh Prolegomena vii the TEM laboratory. I also thank Mrs. Soula Sapountzoglou (mama tou kosmou), Pavlos Gaithatzis and the secretary of the Department Mrs Arete Dimopoulou.I express my sincere thanks to my colleagues who, with their behaviour, gave a unique meaning of the concept "team work" and academic ethics. Those folks are Ioannes Akdamakis, Spyros Gelis, Natasa Tsirika, Giorgos Kofidis, Katerina Aligizaki, and Kalopesa Eleni for their constant encouragement and making a friendly atmosphere in the lab. They made sure not let a day pass without joking, smiling and drinking as well.
