Mainland Southeast Asia experienced a long, sustained period of foraging economy before rice and millet farming spread into this area prior to 4,000 years BP. Although hundreds of individuals from dense cemeteries are found in several hunter-gatherer sites in Guangxi, Southern China, and Northern Vietnam, dating from the early to middle Holocene (ca. 9,000–4,500 years BP), so far, little has been known about food sources in these pre-farming contexts. In particular, plant food resources have been unclear, although they likely were crucial to supporting rather large populations of hunter-gatherers in this region. To investigate this issue, micro plant remains, including starches and phytoliths, were recovered from stone tools excavated at the Cai Beo site in Ha Long Bay of coastal Northeastern Vietnam, and those findings revealed new understanding of the ancient diet. Examinations of those residues indicated that the hunter-gatherers at Cai Beo as early as 7,000–6,000 years BP exploited a broad spectrum of plants, such as taros, yams, acorns, palms, and more. This study exemplifies how maritime hunter-gatherers interfaced with the local plants and generated population growth from about 7,000 to 4,500 years BP. The results help us to conceptualize the early exploitation, management, and potential cultivation of subtropical and tropical plants over the broad geography of Asia and the Pacific before the arrival of rice and millet farming. In particular, the result validates the significance of roots and tubers in the ancient subsistence economy of Southeast Asia. Moreover, from the archaeological context of 4,500 to 4,000 years BP, the rice discovered in this study represents one of the earliest known in Mainland Southeast Asia.

“…However, there are very limited research findings available in terms of the bioactive properties of C. urens flour. According to previous studies by Wimalasiri et al, 2016, the ABTS + radical scavenging activity of C. urens flour was 32.04 ± 7.41 IC 50 (mg/ml) and the ferrous ion chelating capacity of C. urens was 18.91 ± 10.4 IC 50 (mg/ml). According to this study, there was a good positive correlation between TFC and total antioxidant capacity ( R 2 = 0.673), and between TPC and total antioxidant capacity ( R 2 = 0.546).…”

“…According to Table 6, C. urens flour has shown significantly ( p < 0.05) higher TPC (1.38 mg GAE/g dw), flavonoid content (1.79 mg CE/g dw), and carotenoid content (36.18 μg/g DW) compared with those of other commercial flour types. Wimalasiri et al (2016) reported that the polyphenol content in C. urens raw flour was 0.79 ± 0.03 mg GAE/g and this difference could be due to differences in agronomic factors including cultivar variability and climatological conditions.…”

“…Accordingly, C. urens palm, on average, generates about 24 tons/ha per year and is comparable with rice (6 tons/ha/year), corn (5.5 tons/ha), and potato (2.5 tons/ha) (Tanuja & Rajyalakshmi, 2004). Wimalasiri et al (2016) reported that C. urens flour exhibits antioxidant activity in terms of scavenging free radicals, chelating the metal ions, possessing the reducing power, etc. and which supports the scientific evidence behind the health benefits associated with C. urens flour to some extent.…”

The present study aimed to discover the potential of Caryota urens flour to formulate gluten‐free foods. Physicochemical, nutritional, morphological, and gelatinization properties of C. urens flour were evaluated and compared with commercial flours. Crackers were formulated with different levels of C. urens flour (25%, 50%, and 75%) with rice flour and were evaluated for their nutritional properties. Results showed that the C. urens flour contains 67.52% starch, 1% protein and polyphenols (1.38 mg/GAE/g), and also possessed the antioxidant capacity of 3.63 ± 0.13 mgAAE/g and 13.03% α‐amylase inhibition activity. The gelatinization temperature range of C. urens flour (73–81°C) was narrower compared with wheat flour (62–88°C). The protein content of crackers reduced with the increasing levels of C. urens. Crackers with 75% C. urens have shown significantly higher (p < 0.05) phenolic content and α‐amylase inhibition percentage. Results revealed that C. urens flour has good potential as an ingredient for both consumer attraction and giving health benefits. Practical applications Caryota urens is an underutilized palm species mainly distributed in several countries in the South, which shows good potential to be used as valuable food ingredients for the food industry, especially for the formulation of gluten‐free food products. Searching and evaluating the potential of underutilized food crops for the betterment of human beings are vital in terms of food security in a global scenario.

Objective: The objective of this study was to analyze the bioactive compound presence, in vitro antioxidant and antimicrobial potential of Phoenix pusilla root extract.Methods: Extracts were prepared with ethanol, acetone, and hexane by Soxhlet method. Then, the extracts were checked for phytochemicals presence or absence. In vitro antioxidant activity was analyzed by checking its scavenging ability and reducing property. Antibacterial was assayed by well diffusion method and antifungal activity using sabouraud dextrose broth. Results:The results showed that the ethanolic root extract contains alkaloids, flavonoids, saponin, tannin, and triterpenoids have potent antioxidant activity and inhibitory activity against certain Gram-positive, Gram-negative, and fungi. Conclusion:The present study revealed the significance of the plant as a drug. Further, in vivo study is needed to be used as curative agent for different health illness.
