Chemicals in a Plant (by Specific Activity)
Single Plant Synergy Query

This query displays a list of the chemicals with a specific activity in a particular plant.

To enter a query, type the activity, genus, and species in the boxes below:

Capitalization is unimportant. Use an asterisk to wild card values.

Enter the desired chemical activity
Activity (required)
Enter the scientific name
(Genus and species required)
Enter a specific plant part (optional)
Plant Part
(Blank = all parts)

Exclude ubiquitous compounds

Plant Choices - Composition
Plant choices - Phytochemical Databases

This page allows the user to query the database for phytochemicals in one or several chosen plants. These plants can be chosen via scrollbar or entering the first several letters of the name.

Select from the following:

Common Name Scientific Name

Select range of beginning letters for name

 

Should you prefer, you may enter all or part of a name, capitalization unimportant (e.g., mustard).

 Name to be searched:

 

Chemicals in Plants (by Concentration)
High Concentration Chemicals Query

This query displays a list of the chemicals in a particular plant with concentrations greater than a selected number of standard deviations above the mean for concentration among all plants in the database. Activities of these high concentration chemicals are listed subsequently.

To enter a query, type the scientific name (genus, species) or common name and plant part. Then click on the Submit button. Capitalization is unimportant.

Enter plant name:

Genus and species or
Common name
Enter plant part:
Plant Part
Select a standard deviation or type a number in the box below:


1 Standard Deviation
2 Standard Deviations
or

Standard Deviations

Plants (with multiple activities)
Synergy Query

This query displays several user-selectable lists of plants containing chemicals with a multiple activities.
To make a query, select one of the following 2 boxes and choose one or more of the plant categories.

Plants and chemicals with activity, grouped and arranged by plants with greatest number of chemicals.
Plant category:

Food .............. GRAS
Medicinal ........ All
  1. Plants and chemicals with activity, grouped and arranged by plants with greatest total concentration of chemicals.
    Plant category:
    Food ............... GRAS
    Medicinal.......... All
Enter the activities in the boxes below Capitalization is unimportant:
First activity

Second activity (optional)

Third activity (optional)

Toxicity (by Phytochemical)
Toxicity query

This query displays a list of the chemicals with their LD data.

To enter a query, type the chemical name in the box below:

Chemical: (case is not important) (% for all chems)

Ethnobotanical Uses (by Plant)
Ethnobotany query

This query displays a list of the ethnobotanical uses for one or more plants. To enter a query, type the genus and species names in the boxes below. Capitalization is unimportant (example: echinacea or Echinacea will return the same items). Use an asterisk to wild card your search criteria (example: Taxus ba* for species of Taxus starting with 'ba')

Scientific name: (Genus required, species optional)

Specific Activities (by Chemical)
Activities of a Specific Chemical query

This query displays a list of activities for a particular chemical. To enter a query, type the chemical name in the box below. Capitalization is unimportant. Click on "Chemical" to see a list of the chemicals in the database.

Chemical (required)
Check to exclude reference citations from activity results (cleaner output).

High-Low Chemical query

This query displays either a HI-LOW or just a list of plants containing a particular chemical. To enter a query, type the chemical name in the box below:
Capitalization is unimportant

Chemical: (required)
View only the top 40 plants with quantitative data. Check to include plants without quantitative data.

Chemical (by Specific Activity)
Chemicals with a Specific Activity Query

This query displays a list of chemicals with a particular activity. To enter a query, type the activity in the boxes below. Capitalization is unimportant

Activity
Check to exclude chemicals without dosage information.

Plants (by specific Ethnobotanical Use )
Ethnobotanical use query

This query displays a list of plants for a given ethnobotanical use. To enter a query, type the ethnobotanical use in the box below. Capitalization is unimportant.

Disclaimer

WARNING: Do not consult these databases unless you agree not to hold the compilers or the USDA liable for any errors or omissions. Data were gathered rather randomly from the literature on economic plants, none of which will ever be completely known phytochemically. These data were compiled by human beings, mostly Jim Duke and Stephen Beckstrom-Sternberg, from published, or rarely, personally communicated sources by human beings. To err is human! For any serious studies, values, especially deviant values, need to be rechecked with original sources. Neither the compilers nor the USDA recommend self diagnosis or self medication; the compilers do urge serious studies of herbal alternatives, believing that in many cases, the herbal alternative may contain several synergistic compounds that will, in fact, do what empirical trials have suggested, as recorded in the folklore (See ETHNOBOTANY database). Where these biologically active compounds occur in the edible portions of long established food species, we could be dealing with promising "food farmacy" alternatives. Synergies often double the rates of biological activities, but sometimes increase them an order of magnitude or two or more. Plants usually contain synergistic suites of phytoprotective chemicals which are often responsible for their medicinal uses as well. Evolution would favor synergies and disfavor antagonisms in such suites of compounds. If we have learned anything in the preparation of this database, it is that the levels of biologically active compounds vary widely, often one or two, sometimes more orders of magnitude. An increase in one compound from a suite of compounds is usually compensated for by a decrease in another compound(s). All plants, like all animals, contain toxins and carcinogens. Even commonly ingested food plants, like peanuts, can be fatally allergic to sensitive people.
