Mask Products from Snake Plant Leaves
Sansevieria trifasciata is a species of flowering plant in the family Asparagaceae, native to tropical West Africa from Nigeria east to the Congo. It is most commonly known as the snake plant, mother-in-law’s tongue, and viper’s bowstring hemp, among other names. It is an evergreen perennial plant forming dense stands, spreading by way of its creeping rhizome, which is sometimes above ground, sometimes underground. Its leaves grow stiff vertically from a basal rosette. Mature leaves are dark green with light gray-green cross-banding and usually ranges from 70–90 centimeters (28–35 in) long and 5–6 centimeters (2.0–2.4 in) wide, though it can reach heights above 2 m ( 6 ft) in optimal conditions.
The use of masks is an effort to prevent health problems caused by the entry of harmful pollutants such as sulfur dioxide, nitrogen dioxide, and formaldehyde. Pegnan glycosides from the tongue-in-law plant (Sansevieria trifasciata) can reduce pollutants to other harmless substances. This study is aimed at developing mask products using pregnane glycoside extract from the tongue-in-law leaves as an absorbent of harmful pollutants. Extraction of preganene glycosides was carried out by maceration using 96% ethanol. Identification of the pregnane glycoside content was carried out with Lieberman-Buchard reagent and ultraviolet spectrophotometry. Pollutants tested include sulfur dioxide, nitrogen dioxide, and formaldehyde.
