Identification and characterisation of serine protease inhibitors from Araucaria angustifolia seeds [PDF]
Natural Product Research, 2016 Araucaria angustifolia seeds are characterised by a relatively high content of starch and protein. This study aimed to verify the presence of α-amylase inhibitors in the seeds and to characterise a trypsin inhibitor found in the embryo tissues. Inhibitor purification was carried out by the saline extraction of proteins, acetone precipitation and ...

Uncoupling human and climate drivers of late Holocene vegetation change in southern Brazil [PDF]
, 2018 In the highlands of southern Brazil an anthropogenitcally driven expansion of forest occurred at the expense of grasslands between 1410 and 900cal BP, coincident with a period of demographic and cultural change in the region.

Starch Degradation Metabolism towards Sucrose Synthesis in Germinating Araucaria araucana Seeds [PDF]
Plant Physiology, 1984 As starch is the main seed reserve material in both species of Araucaria of South America, A. araucana and A. angustifolia, it is important to understand starch breakdown in both embryo and megagametophyte tissues of Araucaria seeds. Sugar analysis by thin layer chromatography indicates that sucrose is the main sugar produced in both tissues.

Elemental composition and nutritional value of Araucaria angustifolia seeds from subtropical Brazil [PDF]
Journal of Food Science and Technology, 2019 Consumed by populations in South America, Araucaria angustifolia seeds have received little study regarding elemental composition and nutritional value. Thirty-five seed sites from subtropical Brazil were sampled and seed concentrations of C, N, K, Ca, Mg, P, Fe, Zn, Mn, Cu, Mo, Ni, Co, Cr, Ba, and Cd were determined. The highest concentration of N was

Two cationic peroxidases from cell walls of Araucaria araucana seeds
Phytochemistry, 1995 We have previously reported the purification and partial characterization of two cationic peroxidases from the cell walls of seeds and seedlings of the South American conifer, Araucaria araucana. In this work, we have studied the amino acid composition and NH2-terminal sequences of both enzymes.
