replies: text: I've fixed this one now... and I fixed the one above yesterday.  But, hey guys, the really smart thing to do in these cases is to write a short page that really is about the genus concerned - even if it's only a taxobox and a few basic facts culled from the web.  seglea 07:20, 30 Jun 2004 (UTC)

replies: text: I looked it up--it also comes from caulis, by way of the Italian cavolo.--Curtis Clark 04:30, 3 September 2005 (UTC)
replies: text: It goes back further than that, to Proto Indo-European, although it may have been mostly recently reborrowed into German from Italian. It's interesting that it shows up in a Germanic lanuage, Romance language, a Celtic language (cf. colcannon), and I had a good Slavic example that I can't remember right now. And it shows up in most of the English words for Brassica oleracea cultivars (through borrowing from other languages): cauliflower, kale, broccoli, kohlrabi and a cabbage dish, coleslaw.Plantdrew (talk) 22:00, 1 February 2013 (UTC)

message: I'll follow the scheme now given at the APG website (and thus Brassicaceae s.s.) and make a cladogram of Brassicaceae s.l. in the section about taxonomy to explain the topic. I'll try to write the article in a way that it will not be too difficult to merge with Capparaceae if the situation will change. I hope this will be OK for everybody.

Abstract
The cancer-chemopreventive effects of broccoli may be attributed, in part, to isothiocyanates (ITCs), hydrolysis products of glucosinolates. Glucosinolates are hydrolyzed to their respective ITCs by the enzyme myrosinase, which is inactivated by heat. In this study, the metabolic fate of glucosinolates after ingestion of steamed and fresh broccoli was compared in 12 male subjects in a crossover design. During each 48-hour baseline period, no foods containing glucosinolates or ITCs were allowed. The subjects then consumed 200 g of fresh or steamed broccoli; all other dietary sources of ITCs were excluded. Blood and urine samples were collected during the 24-hour period after broccoli consumption. Total ITC equivalents in broccoli and total ITC equivalents in plasma and urine were assayed by high-performance liquid chromatography as the cyclocondensation product of 1,2-benzenedithiol. The content of ITCs in fresh and steamed broccoli after myrosinase treatment was found to be virtually identical (1.1 vs. 1.0 micromol/g wet wt). The average 24-hour urinary excretion of ITC equivalents amounted to 32.3 +/- 12.7% and 10.2 +/- 5.9% of the amounts ingested for fresh and steamed broccoli, respectively. Approximately 40% of total ITC equivalents in urine, 25.8 +/- 13.9 and 6.9 +/- 2.5 micromol for fresh and steamed broccoli, respectively, occurred as the N-acetyl-L-cysteine conjugate of sulforaphane (SFN-NAC). Total ITC metabolites in plasma peaked between 0 and 8 hours, whereas urinary excretion of total ITC equivalents and SFN-NAC occurred primarily between 2 and 12 hours. Results of this study indicate that the bioavailability of ITCs from fresh broccoli is approximately three times greater than that from cooked broccoli, in which myrosinase is inactivated. Considering the cancer-chemopreventive potential of ITCs, cooking broccoli may markedly reduce its beneficial effects on health.

There is indeed a "Hugueninia" in the family B., namely:

message: Not sure about the claim of being almost exclusively insect-pollinated - "notable exceptions" that are self-pollinated should at least include A. thaliana as it's a key factor in its use as a model organism!  — Preceding unsigned comment added by 2405:B000:706:2:0:0:177:136 (talk) 23:51, 3 August 2023 (UTC)
