Voynich manuscript

Greetings, fellow lovers of languages. A colleague has given me the assignment to translate (into English) the first line of folio f6v of the Voynich manuscript. The assumptions are that:
(a) the text is in a proto-Romance (or Vulgar Latin) language used in the 15th century
(b) the characters can be transliterated by means of a key which my colleague has provided
(c) the text refers to a common plant which was harvested for food in the Mediterranean at that time.

My first attempt at a raw transliteration is as follows:
loasA t as éeelas doas êos éapéA t éeas éas oméA
where A denotes "free a", a denotes "trapped a", é is the long e, and t is probably a full stop (UK) or period (US).

I am considering the possibilities that:
* the text is not entirely Latin and may include some words from Italian or Neapolitan languages of that era
* the é could alternatively be et (and), in which case the transliteration might read:
loasA t as eteelas doas êtos etapetA t eteas etas ometA
* the terminal s could be the Latin suffix -is or -us, in which case the transliteration might read:
loasA t ais eteelais doas êtios etapetA t eteais etais ometA
or
loasA t aus eteelaus doaus êtous etapetA t eteaus etaus ometA.
* the terminal A could be the Latin enclitic -que, in which case the transliteration might read:
loasque t ais eteelais doas êtios etapetque t eteais etais ometque
or
loasque t aus eteelaus doaus êtous etapetque t eteaus etaus ometque.

I would welcome any ideas from speakers of Latin or modern Romance languages (I speak French and Romanian and can read Italian, Portuguese, Spanish and a few words of Neapolitan).
