Correction to: Journal of Natural Medicines (2018) 72:537–541 https://doi.org/10.1007/s11418-018-1185-y

In the original publication of the article, under the paragraphs “Collection of volatile compound” and “Analysis of essential oil and hydrosol” holding time for the end of GC and GC–MS programs at 180 °C was incorrectly published as “10 min”. The correct time limit is “30 min”.
