“…The second group was typical chemical shifts for pentacyclic triterpenes, for example signals of tertiary methyl group (appeared as singlet at δ 0.84, δ 0.88, δ 0.96, δ 1.12, and δ 1.16) and signals of an olefinic protons (around δ 5.00-δ 5.50). Indeed previous studies reported the presence of some flavonoids and triterpenes in this plant, such as oleanoic acid, ursolic acid, and maslinic acid (Brieskorn 1977;Brieskorn and Riedel 1977).…”

“…The leaves are traditionally used as breast milk simulant (lactagogue) by Bataknese lactating women in North Sumatra (Damanik et al 2006). Many compounds have been identified from P. amboinicus leaves (Brieskorn 1977;Brieskorn and Riedel 1977). The antihyperglycemic (Viswanathaswamy et al 2011), and anti-inflammatory (El-Hawary et al 2012) potential of the plant extracts were reported.…”

Plectranthus amboinicus has been reported to have antidiabetic and antioxidant activities. Environmental factors might influence the plant’s secondary metabolite profile and its beneficial properties. NMR-based metabolomics was used to show phytochemical variations between specimens of P. amboinicus grown in Japan and Indonesia. The results showed that flavonoids and triterpenes were among the discriminating factors of the variation between the two groups. Targeted comparative analysis of the concentration of the specific flavonoids of the plants using a validated HPLC-MWD method showed that the Japanese samples contained a higher concentration of total flavonoids compared with the Indonesian samples. The Japanese and Indonesian samples contained 1100.6 ± 5.1 and 532.4 ± 1.8 µg/g luteolin, and 584.5 ± 7.4 and 571.7 ± 11.6 µg/g apigenin, respectively. Eriodyctiol was detected only in the Indonesian samples. Contrarily, more intensive DPPH reduction and α-glucosidase inhibition activities were found in the Indonesian samples (IC50 14.4 ± 1.2 and 24.0 ± 0.3 µg/mL for the DPPH assay, 1181.9 ± 113.5 and 4451.4 ± 290.0 µg/mL for α-glucosidase inhibition, respectively). Thus, flavonoids might not be the only group of compounds related to the aforementioned bioactivities. This should be confirmed by further research targeting other groups of compounds, such as triterpenes.

Caesalpinia pulcherrima and Delonix regia are generally grown in Thailand and used in traditional medicine having medicinal therapeutic effects. The antioxidant ability of seed extract has been presented by few investigators whereas no data has been reported the different antioxidant activity between embryo, endosperm and seed coat extracts from both species. Difference types of tissues and varieties may cause a difference seed contents and antioxidant characters. Hence, the main aim of this study is to compare the free radical scavenging activity of embryo, endosperm and seed coat extracts between C. pulcherrima and D. regia. It was found that the phenolic compounds found in embryo extract (100, 200, 400 and 1,000 g/ml) of C. pulcherrima (16 to 238 g gallic acid equivalents) and D. regia (33 to 379 g gallic acid equivalents) were significantly higher than those of endosperm and seed coat extracts. The percentage of DPPH scavenging activity of seed coat extracts of C. pulcherrima (8.68 to 76.16) and D. Regia (2.69 to 9.63) were higher than those of endosperm and embryo extracts. In addition, the percentage of DPPH scavenging activity of seed coat extracts of C. pulcherrima was statistically significant higher than D. regia. Finally, we can conclude that (1) the highest phenolic contents were found in embryo extract, (2) the seed coat extract of C. pulcherrima had the highest antioxidant activity (3) phenolic contents and antioxidant activity of seed coat extracts of C. pulcherrima were significantly higher than D. regia, and (4) the total contents of phenolic compounds and the percent DPPH scavenging activity were depended on types of tissues and species.
