Other claims from this paper (8)
- Observation The 50% EtOH leaf extracts of both roselle varieties were rich in neochlorogenic acid and cryptochlorogenic acid.
- Observation The 50% EtOH leaf extracts of both roselle varieties were rich in rutin and nicotiflorin.
- Observation Taitung No. 6 leaves uniquely contained higher levels of anthocyanins, including delphinidin-3-O-sambubioside and cyanidin-3-O-sambubioside.
- Observation n-Hexane extracts of roselle leaves were identified as potential sources of vitamin E and alpha-linolenic acid.
