Abstract

A study of the essential oil content in basil (Ocimum sanctum) and red lemongrass (Cymbopogon nardus L. Rendle) originally grown in Flores island has been conducted. The purpose of this study was to identify the chemotype of the essential oils obtained over stahl distillation using GC-MS. The Ocimum mainly consisted of 55% eugenol following by minor trans-alfa-bergometena, patchulana, and linalool. Meanwhile, the chemotype of the red lemongrass (Cymbopogon nardus L. rendle) were citronellol (22%), citronella, cyclohexamethanol, and viridiflorol.

Abstract

Aromatic aldehydes including chalcones are known to have various biological activities. Such compound i.e. 2,4,5-trimethoxybenzaldehyde has also proven to be a COX-II inhibitor anti-inflammation and colon and breast cancer chemoprotective agent. This study aims to determine the toxicity of 2,4,5-trimethoxybenzaldehyde against artemia salina L. larvae according to the Brine Shrimp Lethality Test (BSLT) method. The results showed that the 2,4,5-trimethoxybenzaldehyde has a toxic effect with its LC50 is 70.12 µg/mL
