The amount of food waste throughout the world has become quite alarming and is contributing to lower food resources. The study aimed to extract and characterize the polyphenols from corn silks at immature and mature stages through conventional and green extraction techniques. Purposely, corn silks, which are some of the by-products of corn, (Zea mays L.) were collected and subjected to proximate analysis including moisture, ash, protein, fiber, and minerals. Secondly, the antioxidants from both immature and mature corn silks were extracted by techniques involving supercritical and ultrasound extraction alongside conventional extraction. The results displayed a promising quantity of protein and fiber along with calcium, magnesium, sodium potassium, and copper. Among the extraction techniques, supercritical extraction at 3,000 Pa acquired the highest total phenolic contents (TPC), total flavonoids (TF), 2, 2-diphenylpicrylhydrazyl (DPPH), ferric-reducing antioxidant power (FRAP) activities as 128.08 ± 3.74 mg GAE/100 g, 86.73 ± 2.75 mg CE/100 g, 106.73 ± 5.10%, and 73.52 ± 2.33 μM Fe + 2/g, respectively, followed by the ultrasound and conventional extraction techniques. Between the immature and mature corn silks, the highest antioxidant activity was displayed by immature corn silks.

Seed dispersal by ants is one of the important means of migration for adherent plants. Although many myrmecochorous plants have seed with elaiosome which is nutritional reward for ants, some seeds without elaiosomes are also dispersed by ant species. We tested seed dispersal by ants using the achlorophyllous and myco-heterotrophic herbaceous plant Monotropastrum humile, whose seeds do not have elaiosome, and require a fungal host for germination and ultimately survival. We performed a bioassay using seeds of M. humile and the ant, Nylanderia flavipes, to demonstrate ant-mediated seed dispersal. We also analyzed the volatile odors emitted from M. humile seeds, and conducted bioassays using dummy seeds coated with seed volatiles. Although elaiosomes were absent from the M. humile seeds, the ants carried them to their nest. They also carried the dummy seeds coated with the seed volatile mixture to the nest, and left some dummy seeds inside the nest and discarded the rest of the dummy seeds outside the nest with a bias towards locations with moisture conditions conducive to germination. We concluded that seeds of the myco-heterotrophic, herbaceous species were dispersed by the ants, and that seed odors were sufficient to induce directed dispersal even without elaiosomes. The flesh-fruit producing genus Monotropastrum have probably evolved from the related anemochorous genus Monotropa, which produces capsule fruit. This transformation from anemochory to myrmecochory, presents a novel evolutionary pathway towards ant-mediated seed dispersal in an achlorophyllous plant.
