Brassica Oleracea L

The effects of nitrogen, phosphorus, and potassium on the yield and maturity of cauliflower (Brassica oleracea L. ssp. botrytis cv. Snowball Y) were investigated at a total of nine locations during three successive cropping seasons. Yields were substantially increased at most locations by applications of nitrogen and phosphorus but were only slightly affected by applied potassium. Maturity was slightly delayed by a lack of phosphorus. Maximum yields were generally obtained where N was applied at 112–224 kg/ha, P at 49–98 kg/ha, and K at 93 kg/ha.

Brassica Oleracea L

A factorial experiment was conducted during three successive cropping seasons to investigate the effects of nitrogen, phosphorus, potassium, and manure on the yield and maturity of broccoli (Brassica oleracea L. var. italica Plenck.). Terminal (central inflorescence), lateral (axillary stalk), and total yields were substantially increased by applications of nitrogen and phosphorus. For maximum yields, rates of 175 to 250 kg/ha of N and 100 to 150 kg/ha of P were necessary. Increases in lateral yields and total yields from high rates of nitrogen were obtained only when nitrogen was accompanied by adequate phosphorus. Yields of terminals were increased in only one of three seasons by added potassium. A manure treatment increased lateral and total yields in two seasons, and terminal yields in one season. Maturity was delayed by increasing the rates of nitrogen, and where no phosphorus was applied.

Background: Chinese cabbage or Brassica oleracea L. var. pekinensis is an edible leafy green vegetable in the family of Brassicaceae. Ethnopharmacological studies have shown that the juice of cabbage leaves is commonly used in the treatment of gastrointestinal disorders, irritable bowel syndrome, minor cuts and wounds and mastitis. Objective: This study was aimed to examine the gastroprotective effect of Chinese cabbage (Family: Brassicaceae) juice in rats by using ethanol-induced gastric ulcer model. Methods: Thirty albino male Sprague Dawley rats (150 ± 20 g) were divided into 6 groups with five rats (n = 5) in each group. The normal control group was treated with distilled water while the positive control group was intragastrically administered with omeprazole (20 mg/kg). Cabbage juice at 500 mg/kg was given orally to three experimental groups for 1-day, 7-day and 14-day, respectively. Ethanol (70 % v/v) was orally treated to all rats one hour after the last dose treatment except the normal control group. Results: Results obtained showed that repeated consumption of cabbage juice for 7 days and 14 days exhibited an increase in accumulation mucus and in the levels of superoxide dismutase (SOD), glutathione- s-transferase (GST) and glutathione peroxidase (GSH-Px) as well as a reduction in gastric lesion area induced by ethanol compared with the ulceration control group. Conclusion: In conclusion, the gastroprotective effect of Chinese cabbage juice could be associated with its ability to increase endogenous antioxidant activities of SOD, GST and GSH-Px and mucus secretion in rat stomach.

Latar Belakang: Beta-karoten merupakan salah satu isomer karoten yang bisa ditemukan pada sayuran berwarna hijau tua atau kuning tua (seperti wortel dan brokoli). Brokoli merupakan sayuran yang memiliki kandungan beta-karoten yang cukup tinggi, yaitu 623 IU/100 gram. Namun, proses pengolahan brokoli menjadi hidangan dapat menurunkan kandungan beta-karotennya. Tujuan: Mengetahui pengaruh teknik pengolahan terhadap kandungan beta-karoten pada brokoli. Metode: Jenis penelitian ini adalah observational di laboratorium. Penelitian ini menggunakan rancangan acak sederhana dengan dua kali pengulangan dan satu unit percobaan. Teknik pengolahan yang dilakukan adalah merebus, mengukus, dan menumis. Brokoli mentah digunakan sebagai kontrol. Penelitian dilakukan pada bulan Februari–Maret 2017. Analisis kadar beta-karoten dilakukan di Laboratorium Chem-mix Pratama Yogyakarta dengan metode spektrofotometri. Hasil: Kadar beta-karoten tertinggi terdapat pada brokoli mentah diikuti dengan brokoli yang ditumis, dikukus dan direbus. Persen penurunan kadar beta-karoten yang direbus, dikukus dan ditumis dibandingkan dengan brokoli mentah masing-masing sebesar 45,87%, 33,52% dan 22,25%. Ada penurunan kadar beta-karoten yang signifikan setelah direbus, ditumis, maupun dikukus dibandingkan dengan brokoli segar (p<0,05). Kesimpulan: Kadar beta-karoten pada brokoli mengalami penurunan setelah dilakukan pengolahan dengan cara direbus, dikukus, dan ditumis. Merebus mengakibatkan penurunan kadar betakaroten terbanyak dibandingkan dengan kedua proses lainnya.
