Study on the Technologic Conditions of Purifying Total Pteridium aquilinum Flavonoids by AB-8 Macro-resin Absorption;

Pre-treatment technology of pteridium aquilinum before quick freezing;

Effects of freezing process on quality of pteridium aquilinum and the change of enzymatic activity;

Study on technique of processing fern packaged with soft materials;

Determination of Copper and zinc in schisandra、arimillaria mellea and fern By Flame Atomic Absorption Spectrophotometry;

γ-aminobutyric acid in fern leaves and stems was extracted by leaking, isolated by column chromatography and guantitatively dctermined by dual wavelength thin layer scanning method.

Extract rough flavonoid from pteridium aquilinum var.

Using tender Pteridium aquilinum var.

Analysis and Contrast on the Nutrition Components among Wild and Cultivated Pteridium aquilinum var.latiusculum and Common Vegetables;

Kinetic Property of Polyphenol Oxidase (PPO) in Pteridium aquilinum var.latiusculum;

The present paper Preliminarily studied the influence of pH and Ca~(2+) on the flavonoids accumulation in harvested Pteridium aquilinum var.

Analysis on natritional element of fiddlehead;

Finally, vacuum freeze-drying method was applied to freezing-dry fiddleheads.

According to the theory of vegetation succession,species diversity and population of fiddlehead could be restored in three years by artificial ways of cutting off shrubs and sowing buckwheat in the pine-popular mixed natural forest on Lingkong Mountain of Taiyue,which also benefits growth of arbor trees.
