[問題] 葉黃素單位
各位大大，我看了一些關於葉黃素的 paper，總共出現四種單位
(1) mg: 100 g (不知道怎麼跟 mg L-1 換算)
(2) 20 mg l-1 culture (culture 不知道是甚麼意思)
(3) 4 mg g-1 dry weight
(4) 0.53% d. wt (不知道用%好，還是 mg 好)
我的問題是這些單位的代表意義我不確定，所以不知道要怎麼換算之後可以比較
還希望這個版上有人可以幫忙解說一下
我把原文附在下面，(因為 -1次方無法顯示，只能用-1代替)

Topic1:
Lutein and lutein ester content in different types of Tagetes patula
and T. erecta
Abstract
Relevant quantitative differences were found among the marigold types
which had a total content of pigments ranging from 17 to 570 mg:100 g
in the petals and from 0.4 to 18.6 mg:100g in the calyces.
單位是 (mg:100 g)

Topic2:
Accumulation of astaxanthin and lutein in Chlorella zofingiensis
(Chlorophyta)
Abstract
Lutein, in a free (unesterified) form, was the prevalent carotenoid
during early stages of cultivation (over 0.3 pg cell-1, equal to
4 mg g-1 dry weight,or 20 mg l-1 culture), whereas esterified
astaxanthin accumulated progressively, to reach a maximum
(over 0.1 pg cell-1, equal to 1.5 mg g-1 dry weight,
or 15 mg l-1 culture) in the late stationary phase.
單位是 (4 mg g-1 dry weight, 20 mg l-1 culture)
---------------------------------------------------------
Topic3:
Influence of culture conditions on the productivity and
lutein content of the new strain Scenedesmus almeriensis
Introduction
However, the most remarkable characteristic of S. almeriensis is its
high lutein content of 0.53% d. wt., that has eventually been found to
increase above 1.0% d. wt. under outdoor culture conditions.
單位是 (0.53% d. wt)

問題很長
真的很抱歉
還是希望有人知道可以敲我或回覆
謝謝大家
