Also what compound in the edible berries makes it a good pH indicator (red=acid blue=base)? The leaves make good mosquito repellent (tried it, it works, and good).

The claim that elderberry leaves can be used to add a green coloring to oils and fats is true. According to the Plants for a Future database, elderberry leaves contain a compound called chlorophyll, which gives them their green color and can be extracted and used as a natural dye. This makes elderberry leaves a sustainable and eco-friendly option for coloring oils and fats.

As for the compound in elderberries that makes it a good pH indicator, it is anthocyanin. This compound is responsible for the red, purple, and blue colors in elderberries and can change color depending on the pH level of the substance it is in. This makes elderberries a useful tool for determining the acidity or alkalinity of certain substances.

It is interesting to note that elderberry leaves also have mosquito-repellent properties. This is due to the presence of compounds such as alpha-terpineol and linalool, which are known to repel insects. It is great to hear that you have tried it and can confirm its effectiveness as a natural mosquito repellent. This further showcases the many beneficial uses of elderberry plants.
