Abstract

|
In order to investigate of the fatty acid composition in the needle of Genus Pinus, this study was carried out. The raw materials used in this study were the green needle of Pinus densiflora, Pinus rigida and Pinus thunbergii.
The results obtained are as follows :
1. Three samples such as Pinus densiflora, Pinus rigida and Pinus thunbergii, moisture, Crude protein, Crude Lipid and ash was 61.6%, 5.95% and 6.10% ; 7.46%, 6.95% and 7.63% ; 11.61%, 10.53% and 11.85% ; 2.66%, 2.45% and 2.57% respectively.
2. In the Pinus densiflora, 11 kinds of fatty acids were analyzed and one unknown peak comes out. There are 10 kinds of fatty acid were analyzed in the needle of Pinus rigida and Pinus thunbergii.
3. There are favorable contents of essential fatty acid in the needle of Genus Pinus.
Especially the contents of linoleic acid were 51～55%, alpha linolenic acid were 8.7~9.9% and arachidonic were 2~2.28%.
4. P/S ratio for Pinus densiflora, Pinus rigida and Pinus thunbergii was 6.23, 6.01 and 5.28 respectively. Therfore, there are a lot of polyunsaturated fatty acid in the needle of Ginus Pinus what we obtained.
5. W-6/W-3 ratio for Pinus densiflora, Pinus rigida and Pinus thunbergii was 6.24, 5.64 and 6.37, respectively.
Especially C_(18:2)/C_(18:3) was 5.9, 5.4 and 6.2 respectively.
