Heliyon 2024; 10:e32703. [PMID: 38912482 PMCID: PMC11193021 DOI: 10.1016/j.heliyon.2024.e32703] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/24/2024] [Revised: 06/05/2024] [Accepted: 06/06/2024] [Indexed: 06/25/2024] Open
Abstract
Cocoa pod husk (CPH) is a major residue of cocoa processing industry, while medicinal plant H. hirsuta is used for treatment of malaria and diabetes mellitus in folk medicine. This study aimed to produce microencapsulated powders from saponin-enriched CPH and H. hirsuta extracts and assess their physicochemical, phytochemical, antioxidant, and α-glucosidase inhibition properties. The findings show that the microencapsulated powders were achieved diserable physicochemical properties (moisture of 3.22-4.76 %, water activity of 0.43-0.46, water solubility index of 74.18-88.77 %, particle size of 254.2-719.7 nm, and zeta potential from -6.97 to -15.1 mV). The phytochemical content of microencapsulated CPH powders gained at high levels (total saponin content of 151.87-193.46 mg EE/g DS, total flavonoid content of 33.80-46.05 mg CE/g DS), total alkaloid content of 15.20-24.23 mg AA/g DS, and total phenolic content of 5.41-6.49 mg GAE/g DS). The antioxidant potential of microencapsulated CPH powders using ARSC and FRAP assays was 15.51-18.20 and 9.61-11.89 mg TE/g DS, respectively, while their α-glucosidase inhibition capacity at 100 μg/mL was found at 51.74-52.16 %. The phytochemical content (except total alkaloid content), antioxidant, and α-glucosidase inhibitory potential of microencapsulated CPH powders were smaller than those of microencapsulated H. hirsuta and combined powders. This study reveals that the microencapsulated CPH and H. hirsuta powders were prospective in reducing hyperglycemia activity. Therefore, this study provided an evidence for further application of CPH and H. hirsuta plant for functional food development.

Abstract
Helicteres hirsuta Lour. 1790 is a precious medicinal plant species, especially for treating chronic liver diseases. Genomic data on H. hirsuta are limited. Therefore, this current study aimed to characterize the chloroplast genome of H. hirsuta and reconstruct the phylogenetic relationship among Helicteroideae taxa. Consequently, the complete chloroplast genome of H. hirsuta was 163,404 bp in length and contained 113 unique genes (79 protein-coding genes, 30 tRNA genes, and four rRNA genes). Notably, two introns of clpP gene of H. hirsuta were lost in comparison to that of other Helicteroideae species. The phylogenetic tree based on chloroplast genomes of eleven Helicteroideae species revealed that H. hirsuta was closely related to Reevesia species. In conclusion, our study described the first complete chloroplast genome of H. hirsuta, which is essential for tracing evolutionary history in the Helicteroideae subfamily.

Abstract
Helicteres hirsuta, which belongs to the Malvaceae family, is used in traditional medicine to
treat malaria, diabetes and cervical cancer. While these uses have not been validated in clinical studies
thus far, extracts from H. hirsuta exhibit confirmed antioxidant and potential anti-cancer activity that
warrant critical assessment. The aim of this study was to determine the antioxidant properties of different
parts of the plant H. hirsuta. The antioxidant capacities of methanol extracts of different plant parts,
and specific solvent fractions thereof were determined on the basis of 2,2-diphenyl−1−picrylhydrazyl
(DPPH) radical scavenging and total antioxidant activity assays. The ethyl acetate fraction from the
leaf material of H. hirsuta has the most potent antioxidant activity with the lowest half maximal inhibitory
concentration (IC50) value of 9.50 μg/mL, that is 4 times lower than the IC50 of curcumin. The
amounts of methyl gallate and rutin dominated the extracts at 8.62 ± 0.01 and 6.76 ± 0.02 mg/g, respectively,
out of a total of 21.00 ± 0.01 mg/g active phenolic fraction. The amount of methyl gallate
strongly correlated with total phenolic content and total antioxidant capacity, thus this compound may
be useful as a marker of antioxidant activity in common medicinal plants.

Abstract
Pancreatic cancer (PC) is one of the leading causes of cancer death in Western societies. The absence of specific symptoms, late diagnosis and the resistance towards chemotherapy result in significant treatment difficulties. As such, it is important to find more effective therapeutic agents for the treatment of PC. Helicteres hirsuta Lour. (H. hirsuta) has been traditionally used in many countries for the treatment of various ailments, indicating that it contains potential therapeutic agents. This study aimed to derive different fractions from the saponin-enriched extract of H. hirsuta stem using RP-HPLC and examine the in vitro anti-pancreatic cancer activity of the derived fractions (F0-F5). With the exception of F0, the five fractions (F1-F5) possessed strong inhibitory activity against PC cells at IC50 values of 3.11-17.12 μg/mL. The flow cytometry assays revealed the active fractions caused cell cycle arrest at S phase and promoted apoptosis in MIAPaCa-2 PC cells. The LC/MS analysis revealed that the isolated fractions contained bioactive compounds, such as caffeic acid, rosmarinic acid, sagerinic acid, usnic acid, cucurbitacins and absinthin. It can be concluded that the fractions isolated from H. hirsuta stem exhibit potent in vitro anti-pancreatic cancer activity and thus warrant further in vivo studies to assess their activity against PC followed by isolation of individual bioactive compounds and the evaluation of their anti-pancreatic cancer activity.

Abstract
Catharanthus roseus (L.) G. Don (C. roseus) is a well-known medicinal plant for its source of alkaloids solely found in the leaves. Other parts including the root are usually discarded after the alkaloid extraction. This study sought to investigate phytochemical profiles, antioxidant, antimicrobial and cytotoxic properties of the C. roseus root extract (RE) and its two sub-fractions including saponin-enriched (SE) and aqueous (AQ) fractions. The results showed that the RE was a rich source of saponins (1744.44 mg ESE/g) and phenolics (51.27 mg GAE/g), which comprised of gallic acid (25.74 mg/g), apigenin (1.45 mg/g) and kaempferol (1.58 mg/g). The SE fraction was enriched with 31% of saponins and 63% of phenolics higher than those of the RE; whereas the concentrations of saponins and phenolics of the AQ fraction were lower than those of the RE by 40% and 74%, respectively. The content of gallic acid in the SE fraction was 1.4-fold and 1.5-fold higher than those of the RE or AQ fraction, respectively. The SE fraction demonstrated potent antioxidant capacity, which was significantly higher than the RE or AQ fraction, and also exhibited strong anti-proliferative activity against 11 cancer cell lines including A2780 (ovarian), H460 (lung), A431 (skin), MIA PaCa-2 (pancreas), Du145 (prostate), HT29 (colon), MCF-7 (breast), BE2-C (neuroblastoma), SJ-G2, U87 and SMA (glioblastoma) with low GI50 values (≤ 2.00 µg/mL). The SE fraction was also shown to effectively inhibit the growth of both bacteria (Escherichia coli, Enterobacter aerogenes and Staphylococccus lugdunensis) and fungi (Candida albicans and Aspergillus niger). These findings warrant further investigation to isolate major compounds from the SE fraction and further test their antioxidant, anticancer and antimicrobial activities.

Abstract
Helicteres hirsuta Lour. (H. hirsuta) has been considered as a herbal medicine for the treatment of malaria and diabetes but limited studies have been conducted on its anticancer and antibacterial properties. In this study, the in vitro antibacterial and anticancer properties of the leaf and stem extracts and their two sub-fractions (aqueous and saponin-enriched butanol fractions) prepared from H. hirsuta were elucidated. MTT and CCK-8 assays were employed to assess their in vitro anticancer properties against various cancer cell lines. The antibacterial activity was assessed using the disc diffusion method and minimum inhibitory concentration (MIC) values were determined. The results revealed that the saponin-enriched fractions from H. hirsuta leaves and stems showed the highest antibacterial activity against E. coli (MIC values of 2.50 and 5.00 mg/mL, respectively) and S. lugdunensis (MIC values of 0.35 and 0.50 mg/mL, respectively). Importantly, these saponin-enriched fractions possessed strong anticancer activity in vitro towards a range of cancer cell lines including MIA PaCa-2 (pancreas); A2780 (ovarian); H460 (lung); A431 (skin); Du145 (prostate); HT29 (colon); MCF-7 (breast); SJ-G2, U87, SMA (glioblastoma) and BE2-C (neuroblastoma) at low doses (GI50 values of 0.36-11.17 µg/mL). They especially revealed potent anti-pancreatic cancer activity in vitro against MIA PaCa-2, BxPC-3 and CFPAC-1 cells with IC50 values of 1.80-6.43 µg/mL. This finding provides scientific evidence of the cytotoxic activity of the extracts prepared from H. hirsuta leaves and stems, and suggests further studies to isolate active compounds for development of new anticancer agents from these plant extracts.

Abstract
Ethanol extracts (EE) from fenugreek and quinoa seeds with different total content of inhibitory compounds (TIC, total saponin plus phenolic) were prepared with and without concentration of TIC (CEE -concentrated EE-, and EE, respectively). Their inhibitory activity on pancreatic lipase and α-amylase was assessed by traditional in vitro methods (with or without orbital shaking), and by simulating intestinal digestion. CEE contained higher contents of TIC than EE, being fenugreek superior to quinoa (p < 0.001). The extracts inhibited enzymes in a dose-dependent manner, CEE extracts being stronger (fenugreek for lipase -p = 0.009-, and quinoa for α-amylase -p < 0.001-). Shaking did not impact the activity. Intestinal conditions worsened the inhibition of lipase, but slightly catalyzed the α-amylase. Longer times of reaction worsened activities. The importance of assessing the inhibitory activity of extracts under simulated intestinal conditions is concluded, being fenugreek more interesting than quinoa, especially against pancreatic lipase.
