Phytochemical Profile and Antioxidant Activities of Coleus amboinicus Lour. Cultivated in Indonesia and Poland

Abstract

Coleus amboinicus Lour., Lamiaceae, is a perennial herb that is native to Indonesia and also cultivated in Africa, Asia and Australia. The major phytochemicals responsible for its bioactivity are rosmarinic acid (RA) and its analogues, flavonoids and abietane diterpenoids. The possibility of cultivation in a colder climate would extend the use of this herb and provide new opportunities to herb growers and livestock farmers. Our study to compare feed value and phytochemical composition of C. amboinicus plants cultivated in its original region, Indonesia, and in Poland. The crude protein content was significantly higher in plants cultivated in Indonesia compared to those cultivated in Poland—21% and 13% of dry matter, respectively. The higher ADF contents were detected in C. amboinicus cultivated in Indonesia, 38–41%, in comparison to 34% in plants cultivated in Poland. The phytochemical composition was also significantly influenced by the cultivation location. Polish samples were higher in polyphenols (RA and its analogues), and also had 1.5–2-fold higher antioxidant potential, as measured by DPPH scavenging, phosphomolybdenum reduction and Fenton reaction driven lipid peroxidation. The Indonesian samples contained more diterpenoid compounds, such as dihydroxyroyleanone, and the sum of terpenoids was ca. 10 times higher than in samples from Poland (15.59–23.64 vs. 1.87 µg/g of extracts). In conclusion, C. amboinicus is suitable for cultivation in non-optimal climatic conditions but some nutritional properties and bioactivity are significantly affected.

The Effect of Different Concentrations of Total Polyphenols from Paulownia Hybrid Leaves on Ruminal Fermentation, Methane Production and Microorganisms

“…Polyphenol concentration in PLM was comparable to the finding of Huang et al, [9] study (26.94 mg/g DM and 24.6 mg/g DM, respectively) with Paulownia leaves. The differences in Paulownia leaves materials may be a cause of divergent agronomic management [12] than soil condition. Acteoside was the dominant bioactive substance amongst analyzed polyphenol compounds.…”

“…It has been shown that they have the potential to modulate ruminal microbial fermentation mitigating methane production [10,11]. However, it should be kept in mind that the content of bioactive components may differ among the same species grown under different conditions [12]. Research conducted by Huang et al [9] showed that different levels of bioactive components in Paulownia leaves and Paulownia leaves silage, differing in polyphenolic content (25 vs. 47 mg/g dry matter (DM)), may have different effects on rumen fermentation, including methanogenesis.…”

Abietane Diterpenoids Isolated from Clerodendrum bracteatum and Their Antioxidant and Cytotoxic Activities

“…The DPPH radical scavenging activity of the compound was determined according to the method of Ślusarczyk et al with slight modifications [ 11 ]. Briefly, 0.2 mM solution of DPPH in methanol was prepared and 2.5 mL of this solution were added to 2.5 mL of compound solution in methanol at different concentrations.…”

Dietary Coleus Amboinicus Herb Decreases Ruminal Methanogenesis and Biohydrogenation, and Improves Meat Quality and Fatty Acid Composition in Longissimus Thoracis of Lambs

“…All analyses were performed in triplicate. The present analysis procedure on phenolics fraction was following previous published study [14].…”

“…(CAL) herb is rich in polyphenolic compounds (mostly phenolic acids and avonoids), diterpenes, and alkaloids [10][11][12][13].C. amboinicus grows in tropical regions, including Asia, Africa and Australia, and is used in human medicine for long time [10,14]. Our previous short-term in vitro study revealed the capacity of CAL to decrease CH 4 production and to modulate ruminal FA composition, mainly n-3 polyunsaturated fatty acids (PUFAs) by altering the microbial activity linked to methanogenesis and FA biohydrogenation [13].…”
