Marketed Marine Natural Products in the Pharmaceutical and Cosmeceutical Industries: Tips for Success. Marine Drugs, 12(2) 1 1. MEANING OF PHARMACOGNOSY Pharmacognosy, known initially as materia medica, may be defined as the study of crude drugs obtained from plants, animals and mineral kingdom and their constituents. There is a historical misinformation about who created the term pharmacognosy. According to some sources, it was C. A. Seydler, a medical student at Halle, Germany, in 1815; he wrote his doctoral thesis titled Analectica Pharmacognostica. However, recent historical research has found an earlier usage of this term. The physician J. A. Schmidt (Vienna) used that one in his Lehrbuch der materia medica in 1811, to describe the study of medicinal plants and their properties. The word pharmacognosy is derived from two Latin words pharmakon, ‘a drug,’ and gignoso, ‘to acquire knowledge of’. It means ‘knowledge or science of drugs. Crude drugs are plants or animals, or their parts which after collection are subjected only to drying or making them into transverse or longitudinal slices or peeling them in some cases. Most of the crude drugs used in medicine are obtained from plants, and only a small number comes from animal and mineral kingdoms.

(Giant White Bird of Paradise or Natal Wild Banana; Strelitziaceae), a native of South Africa, is a common horticultural subject in eastern Australia. Recently a small colony of plants was discovered at Minnie Water (c. 60 km NNE of Coffs Harbour, North Coast, New South Wales). The colony is of note as some plants were 8 m tall (suggesting they had been there for some time) and that they were setting viable seed. Seedlings were found within this population and Milne and Luxton have observed that the species is being found in increasing numbers on council land and in National Parks of the area.

Historical Setting of the Guianan Plant Heritage The Guianas are embedded high in the green shoulder of northern South America, an area once known as the "Wild Coast". They are the only non-Latin American countries in South America, and are situated just north of the Equator in a configuration with the Amazon River of Brazil to the south and the Orinoco River of Venezuela to the west. The three Guianas comprise, from west to east, the countries of Guyana (area: 83,000 square miles; capital: Georgetown), Surinam (area: 63, 037 square miles; capital: Paramaribo) and French Guiana (area: 34, 740 square miles; capital: Cayenne). Perhaps the earliest physical contact between Europeans and the present-day Guianas occurred in 1500 when the Spanish navigator Vincente Yanez Pinzon, after discovering the Amazon River, sailed northwest and entered the Oyapock River, which is now the eastern boundary of French Guiana.

University of Ilorin, Ilorin, Kwara State, Nigeria Received: 27 January 2014; Revised: 09 May 2014; Accepted: 15 May 2014 Abstract: Studies were carried out on the effects of environmental differences on the morphology and phytochemical constituents of Dipcadi filamentosa with a view of establishing plant diversity among the different populations. The bulbs were collected from two States in North Central Nigeria. Kabba is located in Kabba-Bunu local Government Area of Kogi State while Kaiama, Sobi and Tanke are in Kaiama, Ilorin East and Ilorin South Government Area of Kwara State respectively. Bulbs of D. filamentosa collected from Kaiama (KB, KM and KS), Kabba (KA), Sobi (SB) and Tanke (TK) were planted in plastic pots at Botanical Garden, University of Ilorin and morphological characters were observed and measured. Phytochemical screenings were carried out to detect presence of secondary plant products. It was observed that all bulb samples collected from Kaiama were phenotypically the same and differed from other samples. Results showed that KB had highest leaf length of 13.10cm while KA failed to sprout at 2 weeks after planting (WAP). The leaf length of SB (46.57cm) and TK (46.43cm) showed no significant difference (p>0.05) from each other but significantly different from the value recorded for KS (27.60cm) and KB (20.23cm) at 10WAP.The maximum leaf area was measured in SB (73.35cm) which showed no significant difference with all the samples except KB (11.08cm).

The species appears to be closely related to Drimia delagoensis and Urginea lydenburgensis, and whereas all are synanthous and produce small, pale-brownish campanulate flowers, several leaf and bulb features clearly distinguish the new species. Key words: Drimia, Hyacinthaceae, Sekanama, South Africa, taxonomy, Urginea, Urgineoideae Introduction Hyacinthaceae sensu APG (2003) comprises ca. 700–1000 species of bulbous plants mostly occurring in Africa, Europe and Asia, with a single genus, Oziroë Rafinesque (1837: 53), present in South America (Speta 1998a, b, APG 2003, Martínez-Azorín et al. 2014). Four subfamilies are accepted in Hyacinthaceae (Hyacinthoideae, Ornithogaloideae, Oziroëoideae and Urgineoideae) corresponding to monophyletic clades (Speta 1998b, Pfosser & Speta 1999, Manning et al.

This new species is characterized by the leaves bearing heterogeneous circular to elongate pustules and the strongly reflexed perigone seg- ments at anthesis. It is at first sight related to Massonia jasminiflora Burch. ex Baker, M. wittebergensis U.Müll.-Doblies & D.Müll.-Doblies and M. saniensis Wetschnig, Mart.-Azorín & M.Pinter, but differs in vegetative and floral characters, as well as in its allopatric distribution. A complete morphological description of the new species and data on biology, habitat, and distribution are presented. Key words: flora, Hyacinthaceae, Massonieae, Southern Africa, taxonomy Introduction Hyacinthaceae sensu APG (2003) includes ca.

  • GENOME EVOLUTION in MONOCOTS a Dissertation
    GENOME EVOLUTION IN MONOCOTS A Dissertation Presented to The Faculty of the Graduate School At the University of Missouri In Partial Fulfillment Of the Requirements for the Degree Doctor of Philosophy By Kate L. Hertweck Dr. J. Chris Pires, Dissertation Advisor JULY 2011 The undersigned, appointed by the dean of the Graduate School, have examined the dissertation entitled GENOME EVOLUTION IN MONOCOTS Presented by Kate L. Hertweck A candidate for the degree of Doctor of Philosophy And hereby certify that, in their opinion, it is worthy of acceptance. Dr. J. Chris Pires Dr. Lori Eggert Dr. Candace Galen Dr. Rose‐Marie Muzika ACKNOWLEDGEMENTS I am indebted to many people for their assistance during the course of my graduate education. I would not have derived such a keen understanding of the learning process without the tutelage of Dr. Sandi Abell. Members of the Pires lab provided prolific support in improving lab techniques, computational analysis, greenhouse maintenance, and writing support. Team Monocot, including Dr. Mike Kinney, Dr. Roxi Steele, and Erica Wheeler were particularly helpful, but other lab members working on Brassicaceae (Dr. Zhiyong Xiong, Dr. Maqsood Rehman, Pat Edger, Tatiana Arias, Dustin Mayfield) all provided vital support as well. I am also grateful for the support of a high school student, Cady Anderson, and an undergraduate, Tori Docktor, for their assistance in laboratory procedures. Many people, scientist and otherwise, helped with field collections: Dr. Travis Columbus, Hester Bell, Doug and Judy McGoon, Julie Ketner, Katy Klymus, and William Alexander. Many thanks to Barb Sonderman for taking care of my greenhouse collection of many odd plants brought back from the field.

  • The South African Species of Dipcadi
    117 The South African Species of Dipcadi by A. A. Obermeyer In the Flora Capensis 6:445 (1897) Baker enumerated 14 species for South Africa. Since then over 50 more “ new ” species have been described for southern Africa, including a large number from South West Africa. As some are known to be poisonous and others are eaten by Bushmen and wild animals, it is essential to bring order into the classification of this genus. It has been necessary to reduce to synonymy a large number of names. Many of the unnecessary “ new ” species were based on variable characters and others resulted because some species flower hysteranthously in spring and later synanthously. It seems also that several hybrids were given specific rank. Baker divided the species into two sections; those with the perianth segments of equal length were classified in the §Tricharis and those with caudate appendages to the outer segments in the §Uropetalum. When the appendages are well developed sectional classification is easy but in some specimens the appendages are very short. Bentham & Hooker, Gen. PI. Ill, 2:809 (1883) pointed out that the length of the appendages varied even in flowers on one raceme and Baker, when describing the Madagascar species, D. heterocuspe, also mentions that short and long appendages occurred on one raceme. As the appendages are formed at an early stage in the bud. even the short ones may be seen to protrude as three short apical teeth. Apparently the species with appendages to the outer perianth-segments are restricted to Africa and Madagscar. Those from Europe and India do not have them.
