Perlakuan tanpa pupuk orgnik cair limbah ikan  ((POCLI))  1 liter air/3 polybag (A1)., (POCLI)  5 cc/1 liter air/3 polybag (A2).,  (POCLI) 10 cc/1 liter air/3 polybag (A3)., (POCLI)  15 cc/1 liter air/3 polybag (A4)., (POCLI)  20 cc/1 liter air/3 polybag (A5)., (POCLI)  25 cc/1 liter air/3 polybag (A6) Masing- masing  polybag  diberikan 333 cc. Parameter agronomi meliputi: 1)  Tinggi selada (cm), 2) banyak daun selada, 3) Panjang (cm), 4) Bobot segar sampel (g) dengan  analisis ragam (Anova).  Kesempulan. Hasil analisis ragam menunjukan bahwa perlakuan POCLI 25 cc/L air/3 polybag (A6)  berpengaruh terhadap seluruh parameter pengamatan selada, umur 14 HST  tinggi 8 cm, umur 21 HST tertinggi 13 cm dan pada umur 28 HST tinggi  20 cm. Pada saat panen menhasilkan jumlah daun selada terbayak 10 helai, daun terpanjang 20 cm, dan bobot sampel terberat  135 g  bila dibandingkan dengan perlakuan lainnya. Usur makro dan mikro didalam POCLI sehingga mendorong,  mempercepat pertambahan ukuran, panjang selada.

Antioxidant And Antimicrobial Activities

The study demonstrated the effects of precursor feeding on the production of glucosinolates (GSLs), flavonoids, polyphenols, saccharides, and photosynthetic pigments in Nasturtium officinale microshoot cultures grown in Plantform bioreactors. It also evaluated the antioxidant and antimicrobial activities of extracts. L-phenylalanine (Phe) and L-tryptophan (Trp) as precursors were tested at 0.05, 0.1, 0.5, 1.0, and 3.0 mM. They were added at the beginning (day 0) or on day 10 of the culture. Microshoots were harvested after 20 days. Microshoots treated with 3.0 mM Phe (day 0) had the highest total GSL content (269.20 mg/100 g DW). The qualitative and quantitative profiles of the GSLs (UHPLC-DAD-MS/MS) were influenced by precursor feeding. Phe at 3.0 mM stimulated the best production of 4-methoxyglucobrassicin (149.99 mg/100 g DW) and gluconasturtiin (36.17 mg/100 g DW). Total flavonoids increased to a maximum of 1364.38 mg/100 g DW with 3.0 mM Phe (day 0), and polyphenols to a maximum of 1062.76 mg/100 g DW with 3.0 mM Trp (day 0). The precursors also increased the amounts of p-coumaric and ferulic acids, and rutoside, and generally increased the production of active photosynthetic pigments. Antioxidant potential increased the most with 0.1 mM Phe (day 0) (CUPRAC, FRAP), and with 0.5 mM Trp (day 10) (DPPH). The extracts of microshoots treated with 3.0 mM Phe (day 0) showed the most promising bacteriostatic activity against microaerobic Gram-positive acne strains (MIC 250–500 µg/mL, 20–21 mm inhibition zones). No extract was cytotoxic to normal human fibroblasts over the tested concentration range (up to 250 μg/mL).

Flavonoids from plants play an important role in our diet. Watercress is a special plant that is rich in flavonoids. In this study, four important watercress varieties were compared with non-heading Chinese cabbage by ultra-high-performance liquid chromatography-electrospray ionization-tandem mass spectrometry (UHPLC-ESI-MS/MS). A total of 132 flavonoid metabolites (including 8 anthocyanins, 2 dihydroflavone, 3 dihydroflavonol, 1 flavanols, 22 flavones, 11 flavonoid carbonosides, 82 flavonols, and 3 isoflavones) were detected. Flavonoid metabolites varied widely in different samples. Both the non-heading Chinese cabbage and the variety of watercress from Guangdong, China, had their own unique metabolites. This work is helpful to better understand flavonoid metabolites between the non-heading Chinese cabbage and the other four watercress varieties, and to provide a reliable reference value for further research.
