3.2. 1。 Drying effect of water chamomile phenol content

extraction

This has an effect on the organic content of dried total chamomile.

The extract is shown in Figure 3. Flowers. Chamomile extract

The content of phenol is higher than 0.5 mg (19.7% g dw).

Among the dried samples, freeze-dried samples were excluded (p 6±0.05). over there

There was no significant difference in total phenol content.

Samples, air and dried frozen Knovalova c 40 years.

Gao Qiong. 198 1 year 1 month 1 day).

Oil content and air for drying chrysanthemums

At 40-45 degrees; Therefore, it is dried under these conditions.

It doesn't seem to affect the content of phenols or essential oils.

Chrysanthemum morifolium However, there is a significant reduction.

Phenol content in 80 kinds of dried chrysanthemum flowers.

(0.05 on page 6). The total * * * decreases with the influence of drying temperature. phenol

It has been reported as other plants. Jurkunin-

Tiitto( 1985) found that the dryness of willow leaves was obviously lower than 50℃

The total content of phenol with high content is 90%

Total phenols can be reduced at high temperature.

Because volatile phenol evaporates and decomposes phenol

Phenolic compounds combine certain elements with other plants,

Therefore, they cannot be used for extraction (Julkunen-

Tito, 1985).

Effect of apigenin 7- glucoside content on drying

Chrysanthemums show a similar trend (Figure 4). The essence of production

Fresh chamomile contains apigenin 7- glucoside.

3.0 0.4 mg/g dry weight, significantly higher than its content.

Drying of samples (0.05 on page 6). There is no significant difference.

Content of apigenin 7- glucoside between chamomiles

The perianth is freeze-dried, air-dried or oven-dried.

40 degrees (2.0 0.4 mg/g dry weight). Maximum decline of apigenin 7- glucoside

The concentration of the dried sample is1.0 0.3 mg/g dry weight.

At the age of 80, the effect dried in apigenin 7- glucoside.

The content of leaves has been previously written by willow (Julkunen-

Tito & ampSorsa, 200 1), but not with chamomile flowers.

There are significant differences (fresh analysis, drying treatment

The room is dry at the age of 22, and air-dried at the age of 60 (or 90℃).

The content of freeze-dried substances decreased obviously.

Apigenin 7- glucoside.
