Peruvian plants

Isotoma longiflora. This Peruvian plant contains an alkaloid, m.p. 190°, forming a hydrochloride, m.p. 160°. Pharmacological results are recorded and it is suggested that the alkaloid resembles lobeline of which it may be a derivative (Sanchez, Rev. Med. expU, (Peru), 1945, 4, 284 Chem. Abstr., 1948, 42, 1350).

Insect Antifeedants from the Peruvian Plant Alckomea triplinervia... 

The boll weevil antifeedants, anthranilic acid, gentisic acid, senecioic acid, trans-cinnamic acid, trans-cinnamaldehyde and camphor have been Isolated from the Peruvian plant Alchornea triplinervia (Euphorbiaceae). Anthranilic acid and camphor also showed significant Inhibition of growth of the tobacco budworm. 

Those plants which showed total Inhibition of feeding were fractionated and examined In additional bioassays using the tobacco budworm. Three of the plants which were selected for further examination include the Peruvian plants Alchornea triplinervia (Euphorbiaceae) and Machaerlum florlbundum Bentham (Leguminosae) and the Mississippi plant Heterotheca camporum (Compositae). 

This sweetener is extracted from the Peruvian plant Stevia rebaudiana. It is legal in Japan but not elsewhere.

As mentioned earlier, any information obtained from the artifacts of a preliterate society helps us to understand them. There is another very important reason to determine the nature of the dyes used in museum textiles. This applies particularly to textiles which are to be exhibited. Thanks to the work of Padfield and Landi (15), we have a reasonable amount of information about the lightfastness of natural dyes. With some exceptions, indigo, madder, and cochineal are the most important they have relatively poor lightfastness. We shall have to determine the fastness of the yarns dyed from Peruvian plants. When we know these facts, we can then help the curator or conservator to make decisions regarding exhibition, lighting, conditions of storage, and safety of conservation treatments. 

We wish to thank Nora Fisher of the Museum of International Folk Art, Sante Fe, New Mexico, for permission to report on the results obtained on the samples from her collection of Mixtec textiles. We thank Barbara Mullins for sharing with us her samples of dyeings from Peruvian plants. 

Pentacyclic oxindole alkaloids. From the same laboratories at the University of Mississippi still later in 2001, a study of the 7-deoxyloganic acid and a series of pentacyclic oxindole alkaloids from the Peruvian plant Una de Gato or Cat s Claw was reported. This plant is indigenous to the Peruvian rainforest and used in traditional medicine by native people for a variety of ailments. 

Insecticidal properties of withanolides were first noticed on components isolated from the Peruvian plant Nicandra physaloides. Nicandrenone (Nic-1) (90), the major component isolated from this plant, was known by its bitter taste and its insecticidal properties. [58-61]...
