Morphological diversity, total phenolic and flavonoid content of Echinacea purpurea cultivated in Karangpandan, Central Java, Indonesia. Biodiversitas 21: 1265-1271. Purple coneflower (Echinacea purpurea (L.) Moench) is a medicinal plant introduced from North America. While it has been introduced to Indonesia long several decades ago. E. purpurea has not been developed as a raw material for herbal medicines in Indonesia as it faces constraints, namely non-uniform production and lack of information on the total phenolic and flavonoid content if cultivated in the country. This study aims to determine the morphological diversity, total phenolic and flavonoid content of three accession E. purpurea cultivated on lowland area (i.e. 493 m asl) in Tegalgede, Karangpandan, Central Java, Indonesia. This study used a Randomized Complete Group Design (RCBD) method with 1 factor, namely 3 accessions of E. Purpurea: A1, A2, A3 each with four replications. Morphological observations, as well as laboratory analysis, were done in this research to collect quantitative and qualitative data. The quantitative data were analyzed using SPSS to test the difference. We found there is significantly different results E. Purpurea accession in term of plant height, wet stover weight, number of leaves, root weight, root length, number of branches.

Buas-buas, meniran, secang, and rosella have biological and pharmacological activities as antioxidants. The combination of the four plants is expected to provide a more potent synergistic effect on antioxidant activity. The purpose of this study was to analyze the total phenol content, total flavonoids, and antioxidant effects before and after combination. The combination of extracts, buas-buas, meniran, secang, and rosella which are used in sequence is (1: 1: 1/2: 1/2), (1: 2: 1/2: 1/2), and (2: 1 : 1/2: 1/2). Plants used in the form of simplicia was extracted by maceration method. Radical capture activity uses DPPH and IC50 values are determined. Determination of total phenol is expressed equivalent to gallic acid. Total flavonoids are expressed as quercetin equivalents. The phenol and flavonoid content obtained are then correlated with antiradical activity. The results showed that the best IC50 values were in the combination of ratios (1: 1: 1/2: 1/2) that is (11.0 µg / mL), then (1: 2: 1/2: 1/2) which was 13.3 µg / mL, and (2: 1: 1/2: 1/2) which is 19.4 µg / mL. The highest total phenolic and flavonoid content in the ratio (1: 2: 1/2: 1/2) is 33.57% w/w EAG and 74.00% w/w EQ. Correlation analysis between IC50 values with total phenolic and flavonoid contents showed a positive correlation with R2 values of 0.8236 and 0.0102 with positive slope. Thus, it can be concluded that the total phenol content influences free radical scavenging activity by 82.36%, while the effect of total flavonoid content was only 1.02%.

Honey is a well-known natural sweetener and is rich in natural antioxidants that prevent the occurrence of oxidative stress, which is responsible for many human diseases. Some of the biochemical compounds in honey that contribute to this property are vitamins and phenolic compounds such as phenolic acids and flavonoids. However, the extent to which these molecules contribute towards the antioxidant capacity in vitro is inconsistently reported, especially with the different analytical methods used, as well as other extrinsic factors that influence these molecules’ availability. Therefore, by reviewing recently published works correlating the vitamin, total phenolic, and flavonoid content in honey with its antioxidant activities in vitro, this paper will establish a relationship between these parameters. Based on the literature, vitamins do not contribute to honey’s antioxidant capacity; however, the content of phenolic acids and flavonoids has an impact on honey’s antioxidant activity.

To evaluate the antioxidant potential of less valued green leafy vegetables of Bangladesh, the methanolic extracts of Alternanthera sessilis, A. philoxeroides, A. paronychioides, Glinus oppositifolius and Portulaca oleracea were subjected to assay for total phenolic content, total flavonoid content and DPPH free radicle scavenging activity. Among the studied materials, A. sessilis showed the highest phenolic and flavonoid content. However, G. oppositifolius presented the lowest phenolic content (14.53 ± 0.48 mg of GAE/g of sample) and P. oleracea exhibited minimum (7.005 ± 0.25 mg of RUE/g of sample) flavonoid content. DPPH radical scavenging activity was found to increase with increase in the concentration of each individual material. A. philoxiroides (IC50 = 6.07 ± 0.27 μg/ml) was found as the most active in DPPH radical percentage inhibition, which was followed by A. sessilis (IC50 = 7.17 ± 0.67 μg/ml). Interestingly, A. paronychioides, in spite of having good amount of total phenolic and flavonoid content, showed less DPPH scavenging activity. No linear relationship was found to exist in case of the total phenolic, flavonoid content and DPPH scavenging activity among G. oppositifolius, P. oleracea and A. paronychioides. The results from different methods may differ substantially because each complex chemical reaction generates unique values. However, all the five plants exhibited creditable antioxidant activity and thus consumption of these vegetables may play important role in combating oxidative stresses and thereby help in retaining good health.

Background: The current research was undertaken on dried fruits of Capparis moonii to screen its potential for immunomodulatory and cancer indications with identification of phytoconstituents by chromatographic techniques.Methods: Methanolic (MECN), hydro-methanolic (HMECN) and aqueous extracts (AQCN) of Capparis moonii were subjected to high performance thin layer chromatography (HPTLC) and high-performance liquid chromatography (HPLC) after studying the total phenolic and flavonoid content by using rutin and gallic acid as standards respectively as well as undertaking powder characteristics and preliminary phytochemical screening. Immunomodulatory activities covered were hemagglutination antibody titre and delayed-type hypersensitivity reaction with the aid of sheep red blood cells (0.5×109) as antigens. The extracts were studied for antioxidant potential. Anticancer prospects were focusing on in vitro cell lines screening (MCF 7 and HCT 15) by Sulforhodamine B assay method and potato disc assay.Results: The total phenolic and flavonoid content of MECM, HMECM and AQCM fruits extracts were found to be 0.20, 0.11 and 0.47 mg of gallic acid/g and 78.3, 18.8 and 64.4 mg of rutin/g respectively. Rutin and quercetin were confirmed by HPTLC and HPLC showing well resolved peaks. IC50 values in antioxidant studies were found to be significant with all the extracts. Significant immunomodulatory effect was noticed at 200mg/kg in both models (high antibody titre levels and decrease paw volume after 48 h). Unsatisfactory results were observed with selected cell lines and disc assay.Conclusions: Thus, selected fruits may probably have immunomodulatory potential due to presence of flavonols (rutin and quercetin).

Paku atai plant (Angiopteris ferox Copel), specifically the tuber has been used empirically as an anticancer and antidote materials by Dayaknese in West Kutai, with limited scientific study. Thus, this research had been conducted to determine and evaluate the total phenolic, flavonoid content of this plant along with the antioxidant and toxicity profile. The research used several extracts’ solvents including extraction with ethanol (crude extract, CE) and subsequently partitioned with n-hexane (HF); ethyl acetate (EF) and ethanol aqueous (EAF). The resulted crude extract and fractions were then analyzed through colorimetric method to determine the phenolic and flavonoid total; with DPPH and FRAP to observe the antioxidant activity; and using BSLT method to evaluate the toxicity activity. The results showed that the EF fraction provided the strongest antioxidant activity with IC50 value of 13.79 μg/mL and iron reduction with FRAP value of 387.5±6.41 µM/g. However, a high correlation was observed between the antioxidant and the total phenolic content (r2 = 0.970 - 0.974) but little correlation in total flavonoid (r2 = 0.345 - 0.373). Furthermore, the EF (19.56±7.35) showed the highest toxicity activity followed by CE (22.42±2.10), HF (39.52±7.38), and EAF (41.75±5.10). Therefore, the paku atai tuber can be potentially developed as a natural antioxidant and anticancer material.
