“…Although total phenolic and favonoid content are defnitely important indicators of antioxidant activity, DPPH radical scavenging activity is considered more important because it directly measures the ability of a substance to scavenge free radicals, which can cause cellular damage and contribute to various diseases [45]. A wide range of antioxidants can improve DPPH radical scavenging activity, including vitamin C, carotenoids, favonoids, and phenolic compounds [46]. Te important fact is that both red and blue light are known to activate the production of various antioxidants in plants.…”

Motherwort (Leonurus japonicus Houtt) is an important medicinal plant known for its excellent antioxidant properties. Nonetheless, in South Korea, its availability remains limited due to the challenge of low seed germination rates, affecting field production. To tackle this problem, it is imperative to focus on controlled production methods. In our study, we conducted experiments in a laboratory setting, employing various combinations of light-emitting diode (LED) lights to cultivate motherwort. The influence of LED light quality on seed germination, initial growth, and functionality of motherwort is evaluated. The germination rate of motherwort ranged from 36.1 ± 7.35% to 75.0 ± 1.60%, and the highest value was observed in the red LED 100% treatment. The mean shoot length also varied depending on LED light quality. The longest shoot length (3.45 ± 0.13 g) was obtained in the red LED 100% treatment. The highest shoot weight (0.266 ± 0.011 cm) and root weight (0.051 ± 0.008 cm) were obtained in the red LED 70% and blue LED 30% mixed treatment. The total phenolic content of the motherwort sprout ranged from 2.50 ± 0.30 mg GAE/g to 3.01 ± 0.09 mg GAE/g, with the highest value from the white LED (control) treatment, but no significant differences were observed among the treatments. The red LED 30% and blue LED 70% mixed treatment showed the highest total flavonoid content (11.62 ± 0.79 mg QE/g) and DPPH radical scavenging activity (57.64 ± 2.95%). The red LED 70% and blue LED 30% mixed treatment had a similar level of DPPH scavenging activity as the control, and there was no positive or negative effect on the functionality of motherwort sprout. Overall, the results suggest that the red LED 70% and blue LED 30% mixed treatment can be effectively used to increase productivity in motherwort without decreasing its important quality.

“…The purified chlorophyll drier powder was dissolved in methanol (50:50, v/v) diluted to a concentration of 3 mg L −1 , filtrated by a 0.45 µm membrane, and analyzed by HPLC as described by Zhang et al [32] and Zeb et al [33] with modification. The HPLC system (Hitachi High-Tech Science, Tokyo) with a Mightysil RP-18 GP column (250 mm × 4.6 mm, 5.0 µm) (Kanto Chemical Holdings, Tokyo, Japan) was equilibrated with a mobile phase consisting of ethyl acetate/methanol/water (50/37.5/12.5, v/v/v) at a flow rate of 1 mL/min.…”

Chlorophyll is the primary source of color in widespread green plants. It has been investigated in mung bean seed coats and cotyledons. This study aimed to examine chromatic changes in mung beans during heat processing. It observed pigment variation within the cotyledons and seed coats of mung beans. Following thermal treatment from 0 to 50 min, the color of mung bean products changed, primarily from a decrease in chlorophyll content in the seed coat (from 6.57 to 1.28 mg/100 g, with significant differences. p < 0.05), accompanied by the formation of tawny pheophytin. However, the b value of mung bean seed coat showed an increasing trend with significant differences (yellowness, 21.55 increasing to 34.85, p < 0.05). Interestingly, the total flavonoid content in the seed coat tended to increase with thermal time (2.93 to 18.74 µg/mg) with statistical differences (p < 0.05). The condensation reaction of flavonoids with other polyphenolic compounds formed dark-brown polymers, resulting in a significant decrease in brightness (L value) of the cooking solution with thermal processing time (p < 0.05). Thus, the chlorophyll extraction and purification of the mung bean seed coat confirmed the morphological change of chlorophyll combined with the Maillard reaction, resulting in the color change after thermal treatment. It showed that a significant reason for the discoloration of mung beans was pheophytin from chlorophyll in the processing process.

A field experiment was carried out in the agricultural season 2021-2022 in one of the agricultural fields in the Muqdadiya, Al-Harouniya district, located 40 km northeast of the Baquba district of Diyala governorate. The agrarian soil was classified as silty clay (Soil Survey Staff, 2006). It is located at a longitude of 53° 34’ N and latitude of 56° 04° 45° S. The experiment aimed to study the effect of adding chemical and organic fertilizers and spraying seaweed extracts on NPKS concentrations and cauliflower yield. The investigation included three factors: adding organic fertilizer (buffalo waste) at three levels (0, 5 and 10)% of the terrace’s size, symbolized by M1, M2 and 3M, respectively. It was added at a depth of 0-30 cm a month before planting the seedlings in the field. The second factor was the addition of NPK compound chemical fertilizer (20:20:20) at two levels (0 and the full fertilizer recommendation is 300 kg H-1 when planted as a feed) and symbolized by 1 C and 2 C, respectively. The third factor is spraying seaweed extract with three levels (0, 2 and 4) ml L-1 illustrated by A1, A2 and according to an RCBD randomized complete block design with three replications. The experiment results showed that adding organic fertilizer (10% of the size of the terrace) led to a significant increase in the head’s weight, reaching 1.611 kg. The results of the experiment showed that the addition of organic fertilizer (10% of the size of the terrace) led to a significant increase in the weight of the head, as it reached 1.611 kg plant-1, the sulfur concentration in the fruits was 2.00 mg sulfur kg-1, the nitrogen concentration in the leaves was 4.68%. The phosphorous concentration in the leaves was 25%, and the potassium concentration in the leaves was 2.05%; chemical fertilization also increased head weight from 1.385 kg. Plant-1 to 1,108 kg Plant-1.There was an increase in each of the sulfur concentrations in fruits from 2.00% to 1.53%, in the nitrogen concentration in the leaves from 4.60% to 3.48% and an increase in the phosphorous concentration in the leaves from 0.37% to 0.26% and an increase in the potassium concentration in the leaves from 2.78% to 2.27 %, spraying seaweed extracts at a concentration of 4 mmol. L-1 led to a significant increase in head weight, which reached 1.282 kg. Plant-1, nitrogen concentration in leaves 803% and potassium concentration in leaves 2.58%.As for the triple interaction .Keywords: chemical fertilization, organic fertilization, seaweed extracts, cauliflower.
