Supercritical CO2 extractions were performed

by an SFE-400 thermal pump (Supelco), equipped

with a 10 cm3 internal volume extractor. The

extraction pressure could be adjusted in 100 psi

increments up to a maximum pressure of 4000 psi.

The temperature range was 30±200C. The

extracted substances were recovered in a vial con-

nected to a restrictor. At each run the rate ¯ow

was maintained at about 500 cm3/min. Several

methods were used for the total or partial removal

of water from the tomato samples submitted to

the supercritical ¯uid. In all cases the samples were

protected from the action of both light and oxygen

in the air in order to prevent them from damaging

the dye. The extractions were performed on ripe

tomato pulp or dry skins, since they contain about

5 times as much lycopene as in the whole tomato

pulp [15].

The extractions were initially conducted on

whole fresh tomatoes, ground and ®ltered in a

vacuum. In order to adsorb the remaining moist-

ure, the samples were mixed with silica gel. The

measurements were carried out on ``camone''

greenhouse tomatoes, grown in Sardinia and on

®eld tomatoes. Extractions were subsequently

carried out on the skins and dried seeds of ®eld

tomatoes.

The tomato skins and seeds were dried for 24 h

in an air drier at 35C and stored at ÿ5C. The

product was ground before being extracted.

The extractions were run by submitting 2.5 g of

fresh or dry ground samples to di€erent pressures

(2500±4000 psi) and temperatures (40±80C) for

30 min, both in the presence (1 ml) and absence of

an entrainer. The extracts coming out of the

restrictor were collected in ethanol and analysed

by HPLC.

Update:

Lycopene and b-carotene were determined on a

Hewlett Packard 1050 HPLC, equipped with an

autoinjector and UV±visible detector, Spherisorb

column C18, 5 mm, 25 cm 4.6 mm.

Update 2:

A mixture of methanol, THF, and water in a 67:27:6 ratio with

a ¯ow of 1 ml/min (2 ml injection volume) was

used as the mobile phase; the detection was per-

formed at 446 nm, corresponding to a maximum

of lycopene. Lycopene and b-carotene were iden-

ti®ed by

Update 3:

comparing the retention times of the two

pigments in the extraction mixture with those of

their respective standard compounds (Sigma pro-

ducts). Lycopene was also identi®ed by comparing

the UV-visible, 1H NMR and mass spectra of the

extracted substance with those of standard lycopene.

Update 4:

這是依位外國教授給我的資料 而我的英文不好 我急需要 麻煩各位幫幫我 不然我的工作就完了 感謝各位

Update 5:

請問這是用翻譯機翻譯的還是你自己翻譯的....這邊報告百分之90不能有錯誤 不然我就慘ㄌ...感謝

Update 6:

還有 在請問一下 :

1. Absorption spectrum of the extract in supercritical CO2.

2. Impact mass spectrum of the extract by supercritical CO2.

Update 7:

3. HPLC of the extract at 40C and 4000 psi with theentrainer. The identi®ed components are in the order: ®rst peak(retention time 2.60 min) = reference; second peak (rt 22.69min) = trans-lycopene; 3rd peak (rt 25.22 min) = b-carotene.

Update 8:

4. % yields of lycopene and b-carotene obtained from camone tomatoes and ®eld tomatoes at 40C and 4000 psi

Update 9:

5. % yields of lycopene and b-carotene obtained by supercritical CO2 at 4000 psi and by Soxhlet

Update 10:

6. Lycopene yields of the extractions conducted at di€er-ent temperatures and at 4000 psi.

還有以上這幾句 謝謝

Update 11:

可不可以留個MSN 我還有很多問題 麻煩了

    超臨界二氧化碳提取由SFE-400 熱量泵浦(Supelco) 執行了, 被裝備以一個10 cm3 內部容量提取器。提取壓力能被調整在100 psi 增加由4000 psi 決定最大壓力。溫度範圍是30.200C 。提取的物質恢復了在小瓶被連接到restrictor 。在每個跑率.ow 被維護了在大約500 cm3/min 。幾個方法被使用了為水總或部份撤除從蕃茄樣品遞交給超臨界.uid 。在所有案件樣品被保護免受光和氧氣的行動在空氣為了防止他們損壞染料。提取執行了在成熟蕃茄黏漿狀物質或乾性皮膚, 因為他們包含大約5 次同樣多番茄紅素像在整體蕃茄黏漿狀物質[ 15 ] 。

    提取被舉辦了在整體新鮮的蕃茄, 地面和最初地.ltered 在真空。為了吸附殘餘的濕氣, 樣品與矽土凝膠被混合。測量被執行了在"camone" 溫室蕃茄, 被種植在撒丁島和在.eld 蕃茄。提取被執行了在皮膚和隨後烘乾了.eld 蕃茄種子。蕃茄皮膚和種子被烘乾了為24 h 在空氣烘乾機在35C 和被存放了在5y5C 。產品被研了在被提取之前。提取由遞交的2.5 g 負責操行新鮮或乾燥地面樣品對di.erent 壓力(2500.4000 psi) 並且溫度(40.80C) 30 分鐘, 在存在(1 機器語言) 並且缺乏entrainer 。萃取物從restrictor 出來被收集了在對氨基苯甲酸二裡和由HPLC 分析了。
