'Lemons possess the highest content of Vitamin C of any citrus fruit. (I don't think this is correct - oranges contain more, don't they?)'

Yes, I looked at this as well. One source I have to hand says that they contain 'about as much vitamin C as oranges' .

However, I've a feeling I once contributed in PR to an Entry about a fruit which DID contain the most Vitamin C...

Hmm maybe it was the Entry(s) on kiwi fruit I was thinking of; according to the list attached they contain 98mg/100g compared to 53 foir an orange and slightly less for a lemon:

... but look at the very first Entry on the list, Acer(something, something)...

Hmm, there doesn't seem to be an EG Entry on kiwi fruit . Maybe someone said s'thing about kiwi jelly (not setting due to pectolytic enzymes.... )

A quick search reveals:

In each case, the tables are about halfway down.

Snap! (Boy, are you quick!)

Just addressed posting 120 but there are a few things I'd like to query if thats

when quoting what a fellow researcher has said do I change their quote or leave it as it was originally?

I don't follow on your Crusaders point

Epsom Salts and Lemon Cars

will do a search on whether oranges are more concentrated in Vitamin C than Lemons.

>>Are they all fungus diseases? Also, why are there two groups, are one group significantly more prevalent than the other?

'will do a search on whether oranges are more concentrated in Vitamin C than Lemons'.


Well, that reference I gave you in Post 122 gives you that info - and oranges are more conc than lemons; but kiwi fruit and a couple of other things are even more concentrated.

I'm I didn't read your posting before I wrote that comment.

There's a bit of confusion here:

'This is because lemons contain Vitamin B (anti-scorbutic acid), Vitamin C (ascorbic acid)4, citric acid and iron'.

'anti-scorbutic' is to do with scurvy prevention, in particular in connection to vitamin C which is also called 'anti-scorbutic factor'

Hence sentence should read, 'This is because lemons contain Vitamin B Vitamin C (ascorbic acid, also called anti-scorbutic factor), citric acid and iron'.


(Tell you the truth, I'm not sure that lemons are particularly renowned for containing vit B either).

...indeed, Vit B is a complex of about 12 substances.

According to the Purdue Univ website which you hyperlinked to, lemons contain 3 of these - thiamin, ribflavin and niacin. These are in concentrations of 0.04, 0.02 and 0.1 mg/ml respectively; compared to 53 mg/ml for oranges. So, the vit B composition is virtually negligible.

the units are not mg/ml but mg (total)

No need to apologise - my fault for not making myself clear. I'm not trying to make your life more difficult, I promise - I guess it just comes naturally .

Anyway, I was just suggesting that you change the punctuation so that the sentence reads as follows:

Over the years, travellers such as the Crusaders2 and Christopher Columbus3 have encouraged the spread of lemon trees, so that they are now grown in America, around the Mediterranean and in several greenhouses in less tropical climates.

Incidentally, the final part of that sentence "and in several greenhouses in less tropical climates." doesn't seem very convincing to me. Do you think that something like the following would be better?

and in less tropical climates where they are not exposed to freezing conditions.


You'll work it out!

sorted? I question it as I am unsure what to do by the mg

'I question it as I am unsure what to do by the mg'.

You don't have to do anything, except remove 'vitamin B' as a constituent of lemons. As I explained above, the data in the Purdue Univ website - which you Referenced - shows that the vit B content is negligible when compared to vit C.

O, I might have expressed my opinion more clearly in Post 133; the words I thought should be replaced were 'in several greenhouses'.

If you agree (and you don't have to) the paragraph will read as follows:

Lemons appear to have originated prehistorically from the region of Southeast Asia between India and Southern China. They then spread to Greece during 300 BC, where the Greeks believed that oranges and lemons were a symbol1 of fecundity and love, before settling in Italy in 20 BC. Over the years, travelers such as the Crusaders2 and Christopher Columbus3 have encouraged the spread of lemon trees, so that they are now grown in America, around the Mediterranean and in less tropical climates where they are not exposed to freezing conditions.

I suspect there are two d's in Buddhist.

Lemon battery
A common school experiment involving lemons is to attach electrodes and use them as a battery to power a light. The electricity generated may also be used to power a motor to move the lemons (on wheels) like a car or truck. These experiments also work with other fruit and with potatoes.

just saw on wikipedia
Grrreat read about the lemons
