The weed Alternanthera sessilis, having Green (ASG) and Red (ASR) cultivars, is a member of the Amaranthaceae. Both cultivars are known to possess high medicinal and nutraceutical values as they are widely utilized in traditional medicine. Populations from various Asian regions commonly consume this medicinal weed as part of diet and as therapeutic agent. In general, both cultivars have been employed for treating a broad range of human ailments including cardiovascular diseases, diabetes, hypertension, and inflammatory disorders such as asthma, bronchitis and hepatitis apart from its administration as a painkiller. Following its ethnomedicinal uses, an attempt was made to review and consolidate the phytochemical constituents of ASG and ASR discovered from previous studies that utilized advanced technologies, respective traditional application among different ethnicities of Asia and their established pharmacological properties. All the information in this study was acquired through a literature search of research databases, namely ScienceDirect, Scopus, PubMed and Google Scholar using keywords such as Alternanthera sessilis, Alternanthera sessilis red, dwarf copperleaf and sessile joyweed. The results of each study were reviewed to identify its relevance and the cultivar that was being investigated. All relevant studies were collected and its subsequent results were reported and discussed to provide insights into the health enhancing qualities of ASG and ASR. Inspection of phytoconstituents in ASG and ASR showed the presence of polyphenol, flavonoid, carotenoid, terpenes and alkaloid with polyphenol being the major chemical group found in both cultivars. It was also revealed that whilst ASR is traditionally consumed in China, Malaysia, Singapore, and Taiwan, indigenous usage of ASG is more common in nations such as Sri Lanka, India, and Indonesia. Both ASG and ASR showed potent anti-oxidant, anti-hyperglycemic, antimicrobial, antifungal and hepatoprotective effects while the anti-inflammatory, anti-cancer and analgesic properties were disclosed in ASG only. Further processing and commercialization of this remedial weed as a product benefiting the wellbeing of humans is recommended as Alternanthera sessilis has high potential to be utilized as a curative agent while being a vital ingredient that can be included in daily consumption.

Talinum triangulare (Jacq.) Willd. is a traditional leafy vegetable used by tribal communities for ethnomedicinal and ethnoculinary preparations. This article reviews the current knowledge of its multiple uses, including pharmacological activities and nutritional composition. The literature survey shows that it has been traditionally useful in the treatment of several diseases, such as anaemia, diabetes, measles, and ulcers and the preparation of various traditional foods. Analysis of the literature on its phytochemicals shows its richness in bioactive compounds. Further, research also shows that this plant has antidiabetic, antiobesity, antitumor, antiulcer, hepatoprotective, and neuroprotective activities besides anti‐inflammatory and antioxidant properties. Nutrient analysis of the plant reveals the presence of Ca, Zn, Fe, vitamins C and E, dietary fibre and protein in considerable quantities. The results of the pharmacological studies on the antidiabetic, antiulcer and anti‐anaemic activities provide support in favour of its ethnomedicinal uses. The presence of bioactive compounds and pharmacological activities show the usefulness of this plant as a functional food.

“…Being one of the species of the Amaranthaceae family, Alternanthera sessilis Red (ASR) is a perennial and edible leafy medicinal plant or weed with reddish‐pink and white flowers, whereas the leaves are purplish‐red. Generally, it is consumed as a vegetable, and herbal medicine to prevent liver and cardiovascular diseases [4] . Nevertheless, the plant garners little attention in Asia [5] .…”

This study aimed to fractionate Alternanthera sessilis Red (ASR) crude extracts and determine their antioxidant activities as well as the related active components in the whole plant. ASR was extracted with water and ethanol, and further separated using a Sephadex LH‐20 column. Following the assessments of the polyphenolic contents and antioxidant activities of crude extracts (H2OASR and EtOHASR) and fractions, a HPLC‐QToF analysis was performed on the crude extracts and selected fractions (H2OASR FII and EtOHASR FII). Three water fractions (H2OASR FI, FII and FIII) and four ethanolic fractions (EtOHASR FI, FII, FIII and FIV) were derived from their crude extracts, respectively. EtOHASR FII exhibited the greatest total phenolic content (120.41 mg GAE/g fraction), total flavonoid content (223.07 mg RE/g fraction), and antioxidant activities (DPPH IC50=159.43 μg/mL; FRAP=1.93 mmol Fe2+/g fraction; TEAC=0.90 mmol TE/g fraction). Correlation analysis showed significant (p<0.01) positive correlations between both TPC (r=0.748–0.970) and TFC (r=0.686–0.949) with antioxidant activities in the crude extracts and fractions. Flavonoids were the major compounds in the four selected samples tentatively identified using HPLC‐QToF‐MS/MS, with the highest number of 30 polyphenol compounds detected in the most active fraction, EtOHASR FII.
