Calflora

without comments

What is Calflora?
Calflora is 1. a website you can use to learn about plants that grow wild in California (both native plants and weeds); and 2. a nonprofit organization responsible for providing this service. Calflora is run by the team described above. Information in Calflora comes from many sources: public agencies, non-profits, scientists, private donors, and you!
Find Out About a Plant
You can enter the common or scientific name of a plant to find out about it. Or, use the name wizard to just enter part of a name and have the wizard make suggestions. The result is an illustrated table of plants that match the name you entered. Click one of the plants in the table to learn the details about that plant — in particular, where it’s been observed in California. 
Try it out!

Flora of China

without comments

Flora of ChinaThe diversity of plant species in Chinais extraordinary. With an area almost exactly that of the continental United States, China has nearly twice as many plant species, about 31,000 or one-eighth of the world’s total, versus only about 20,000 for the U.S.A. and Canada combined. This number includes about 8,000 species of medicinal and economically important plants and about 7,500 species of trees and shrubs.The Flora of China will describe and otherwise document these species. The Flora of China is a new work, being an English-language revision of the Flora Republicae Popularis Sinicae (FRPS), with taxonomy reflecting the current understanding of each group. The sequence of families is a modified Englerian system, similar to that used in FRPS; however, the circumscription of some families reflects the present understanding of the groups. All of the vascular plants of China will be covered, including brief descriptions, identification keys, essential synonymy, phenology, provincial distribution in China, brief statements on extra-Chinese distribution, and remarks regarding the circumscription of problematic taxa.

DiscoverAbout
Our web tools can benefit you and your projects. Teachers can design hands-on ecological research projects for the schoolyard or local park without killing specimens. Park managers can track migrations of invasive species. Scientists can map large collections and present information about species. Amateur naturalists can upload images and make a life list of species they find. Environmental educators can build online field guides so simple they can be used even by the youngest beginner.

Everyone can benefit in some way from a partnership with Discover Life. With our powerful integrated web tools, you can:

Keep a life list – store your photographic (or video/audio) records of natural history. It’s your own electronic nature journal – this is a service somewhat like Flickr or Picasa web albums, but linked to species information, map data and more. You can keep thousands of photographs and other data on our site for free, and store associated information as well. To see examples of stored photographs, click here.
Map species you find – every time you enter locality data to one of your photo records, it will instantly map as a point on the Global Mapper. This works similarly to Google Earth, but our mapper is capable of mapping many more points, each of them attached to an individual record of species occurrence. Read the rest of this entry »

Super Natural II

without comments

Super Natural IISuper Natural II, a database of natural products. It contains 325,508 natural compounds (NCs), including information about the corresponding 2d structures, physicochemical properties, predicted toxicity class and potential vendors. Natural products are small compounds synthesized by living organisms. The chemical diversity of these molecules is tremendous and offers inspiration for innovations in medicine, nutrition, agrochemical research and life sciences. Most of the currently used cosmetics and drugs are either natural products or close derivatives thereof.

Department of Pharmacognosy and Pharmaceutical Botany, Faculty of Pharmaceutical Sciences, Chulalongkorn University

without comments

CUShort introduction
Department of Pharmacognosy has several areas of specialization such as Phytochemistry, Natural Products Synthesis, Biotechnology and Cell Culture, Marine Natural Product Chemistry, Standardization of Herbs and Herbarium. Academic staff have expertise in each area. The area of Phytochemistry focuses on the studies of chemical constituents from plants by isolation, purification and structure elucidation of the isolated products. Primary biological activity screening of promising crude extracts and/or pure compounds are also of interest. The area of Marine Natural Product Chemistry studies the isolation, purification, structure elucidation, chemical structure modification and bioactivity screening of new bioactive constituents from Thai marine organisms, such as sponges, soft corals. gorgonians, tunicates and bryozoa, marine microalgae and microorganisms. DNA fingerprinting of medicinal plants is another area of interest. We employ several molecular techniques such as RAPD, AFLP, RFLP, PCR-RFLP, and sequencing for generating markers for authentication of medicinal herbs and crude drugs. We have several equipped laboratories with facilities. Read the rest of this entry »

Harvard University Herbaria & Libraries

History
The rich and varied Harvard University botanical collections trace back to the activities of Asa Gray, who came to Harvard in 1842. Gray arrived at a particularly opportune time in American botanical history. Private collectors accompanying various survey expeditions in the expanding American West were sending back an abundance of specimens to scholars in the East. Gray, who had been collaborating with John Torrey in New York on a Flora of North America, was the ideal person to receive, describe and catalogue them, many of which proved new to science. At the same time Gray used duplicates from those collections to exchange with his colleagues in other parts of the world, who themselves were reaping the fruits of an expanding period of exploration in the Old World. The results of those efforts, which continue to this day, have resulted in a collection cosmopolitan in scope, unique in much of its representation and, with well over five million specimens, among the largest in the world.
