“…Oleic acid has demonstrated the ability to prevent cancer and act as an antiandrogenic [ 55 ]. Additionally, 9,12-octadecadienoic acid, ethyl ester also exhibited anticancer and anti-inflammatory properties [ 56 ]. Thus, volatile compounds found in CS possess various biological activities.…”

“…In addition, corn silk is rich in phenolic compounds and consists of proteins, vitamins, carbohydrates, calcium, potassium, magnesium, volatile oils, sitosterol, stigmasterol, alkaloids, and saponins [ 15 ]. The phytochemical composition of CS extracts is mainly due to the flavonoid content: 6,4′-dihydroxy-3′-methoxyflavone-7-O-glycosides ax-5″-methane-3′-methoxymaysin, ax-4″-OH-3′-methoxymaysin, 7,4′-dihydroxy-3′-methoxyflavone-2″-O-α-L-rhamno-syl-6-C-fucoside 3′-methoxymaysin, 2″-O-α-L-rhamnosyl-6-C-fuco-syl-3′-methoxyluteolin, 2″-O-α-L-rhamnosyl-6-C-quinovosylluteolin, 2″-O-α-L-rhamno-syl-6-C-fucosylluteolin, and 2″-O-α-L-rhamnosyl-6-C-3″-deoxyglucosyl-3′-methoxyluteolin have been identified [ 55 , 56 ]. Meanwhile, the flavone glycoside content includes isoorientin-2-2″-O-α-L-rhamnoside and 3′-methoxymaysin [ 16 ].…”
Zea mays L. Poaceae stigma (corn silk, CS) is a byproduct of agricultural waste and is used as a traditional herb in many countries. CS is rich in chemical compounds known to benefit human health and is also a remedy for infectious diseases and has anti-proliferative effects on human cancer cell lines. In the present study, CS extract has been evaluated for its antioxidant, antibacterial, and anti-tyrosinase activities and its phytochemical composition. The higher total phenolic and flavonoid contents were found in the ethanolic extract of corn silk (CSA), at 28.27 ± 0.86 mg gallic acid equivalent/g extract and 4.71 ± 0.79 mg quercetin equivalent/g extract, respectively. Moreover, the antioxidant content of CSA was found at 5.22 ± 0.87 and 13.20 ± 0.42 mg gallic acid equivalent/g extract using DPPH and reducing power assays. Furthermore, the ethanolic extract of corn silk showed tyrosinase inhibition with an IC50 value of 12.45 µg/mL. The bacterial growth inhibition of CSA was tested using agar disc diffusion and broth dilution assays against Cutibacterium acnes and Staphylococcus epidermidis. It was found that CSA inhibited C. acnes and S. epidermidis with an inhibition zone of 11.7 ± 1.2 and 9.3 ± 0.6 mm, respectively. Moreover, the CSA showed MIC/MBC of 15.625 mg/mL against C. acnes. The following phytochemical compounds were detected in CSA: cardiac glycosides; n-hexadecanoic acid; hexadecanoic acid, ethyl ester; oleic acid; and 9,12-octadecadienoic acid, ethyl ester. After the corn silk cream product was formulated, the product demonstrated stability without phase separation. This research is beneficial for promoting effective ways to use agricultural waste while utilizing the antioxidant, anti-tyrosinase, and antibacterial activities of corn silk. Moreover, the use of technology and innovation to obtain high-value CS extract will benefit the development of commercial cosmetic products by providing safe, natural, and quality ingredients to the consumer.

Introduction: Collection of medicinal herbs having similar effect are collectively known as Gana (group) in Samhita and Vargas (category) in Nighantu. Surasadi Gana is included in 37 of such groups mentioned in Sushruta Samhita, with 21 Herbs completing the group. This article is made in a view to review the importance and utility of few herbs included in Surasadi Gana indicated for the management of respiratory disorders.
Material and Methods: The literature regarding the drugs mentioned in the group, collected from different Ayurveda classics. Research papers are compiled from published sources and discussed in light of therapeutic effects.
Observation and Result: Maximum of the herbs in this group are having properties as Katu rasa (pungent) and Ushna veerya (hot potency). Such herbs are predominantly advised in Kapha (phlegm humour) dominant diseases, viz. Kasa (cough), Shwasa (asthma), Pratishyaya (common cold), Kushtha (skin disorders), Krimi (worm infestation) and Vrana (wound).
Conclusion: The herbs, despite having several Ayurvedic indications, the respiratory tract is the focus of the specific activity.
“…Methyl or ethyl ester of fatty acids also have been identified e.g. pentadecanoic acid 14-methyl-, methyl ester, 9-octadecenoic acid, methyl ester, (E)-octadecanoic acid, n-hexadecanoic acid, and tetradecanoic acid belongs to the class of fatty acids and they have been reported to possess antibacterial, antimycobacterial and low antioxidant activity [27][28][29]. Butanaldehyde has also been identified and scientific literature reported its antimycobacterial activity [30].…”

“…Leading phenolic compound such as catechol was also identified which have been reported to have antifungal activity [32]. L. frutescens also possess cytotoxic activity due to furofuran lignans [6] but cytotoxic fatty acid methyl stearate is also found in GC-MS analysis [29]. Vitamin E and vitamin A precursor phytol part of the chlorophyll side chain which belongs to a class of acyclic diterpene unsaturated alcohol, has been identified as a major compound with strong antidiabetic effects [33].…”
